Main article: TETR.IO
A quick summary of a couple notable badges as well as player counts for each described one. Posted on February 13, 2023 on the official @tetriogame Twitter account[1].

Badges are simple graphics placed on a specific and registered user's userpage or player card signifying that user's achievements. There are up to five badges can be obtained with a brand new account without moderator or admin intervention at the moment, and up to nineteen badges that must be specifically added to your account by an admin for a total of twenty-four known badges as of December 24, 2020. Most badges are timestamped with the format: "Month/Day/Year, Hour/Minute/Second AM\PM" readable after hovering over the badge for a little bit, however in the rare case that a moderator adds a timestamped badge manually, the badgeholder will end up with a rare badge without a timestamp[2][3]. Badges are ordered from left to right, and in some cases only found in the standalone TETRA CHANNEL site, top to bottom from the date they were achieved. For example, if you were to get the Secret Grade badge before INFDEV ended, then got a 20TSD badge, your badges would be ordered "Secret Grade->INFDEV->20TSD". This ordering scheme ignores the lack of a timestamp, as demonstrated on user "animecake"'s profile[4].

"Obtainable Badges"

Ordered from the first badge to the last badge to be added to the game, here is a collection of all the badges any brand-new registered account can obtain without admin or moderator intervention.

Secret Grade

The badge awarded to any player who completes this challenge
An example of a completed Secret Grade. This image complies with the rules defined to the left, and as such would reward one with the badge, if the user in question does not already have it.
Confirmation of the badge which appears in the bottom right corner after topping out. It is unique to the Secret Grade badge, as achieving any other badge will not cause the appearance of such a confirmation.

This was the very first badge players could obtain without the moderators or admins manually adding it, being added on the Ninth of February, 2020 alongside the 0.2.2 update[5]. This is, by far, the easiest badge to obtain by yourself when compared to the five other ones. To obtain it, one must build a Secret Grade pattern in any online or solo mode with the very notable exception of Zen mode and practice mode. (practice mode referring to the online custom room option) Solo custom games that are configured to have no gravity or line limit will be accepted for the badge, and are a rather popular way to complete the achievement. In particular, TETR.IO will check for three simple things when considering whether or not a completed Secret Grade is a Secret Grade:

  1. That the pattern is a ">" shape and not a "<" shape. This is hinted at with the design of the badge itself "bouncing off the right wall" and continuing off to the left.
  2. That the rows 1-19 are fully filled except for the defining diagonal holes in the pattern itself.
  3. That the leftmost block located on row 20 is filled.

If the above requirements are satisfied, simply topout. In addition to taking the game over, running the clock out in timed objective modes, such as Blitz or solo custom games set up with the timed objective, will end the game and show the confirmation without a gameover meaning Blitz Secret Grade runs can be uploaded as a public replay. Clearing the final line in a 40 Lines game with a completed pattern will upload the replay.

Back on December 5, 2020, 2,075 players held this badge[6]. Continuing onto March 7, 2022, which coincides with the publication of 5,000,000 BLAST, this number was further expanded to show that up to 9,173 players had the badge[7]. Information pertaining to the total number of owners was further publicized on the 13th of February, 2023, where the value was revealed to be 13,870 badges, the first to have five digits[1]! The very first player to have this badge is known as Omio9999[8], and can be viewed on their TETRA CHANNEL Userpage[3].

Number 1

The badge awarded to any player who completes this challenge

This badge is automatically awarded to any player confirmed to have beat the current world record in either 40 LINES or BLITZ, through a rather strict replay validation protocol involving every input being played back serverside alongside the exact RNG seed to ensure the run wasn't hacked.

  • The current 40 Lines world record is 0:13.650 as ran by WESTL.[9][10]
  • The current Blitz record has 2,192,472 points and was scored by RTXILE.[11]

It's worth noting that the leaderboards were blank at the start of INFDEV, meaning quite a few #1 badgeholders got the TETR.IO world record with subpar times and scores, to put it bluntly. The leaderboards were also reset at the start of the Alpha phase on March 22, 2020, meaning theoretically; the first players to login, start, and finish a single Blitz run would get this badge as well.

This was the second badge players could obtain without moderator or admin intervention. In fact, it was the only badge players could as of the 0.4.2 update[12], and it stayed that way until the Secret Grade badge came along.

As of December 5, 2020, 19 players possess this badge[6]. Only 17 more players, some who had earned the badge by way of the 5,000,000 Blast competition, had gained this badge inbetween the 3 years that led to February 13th of Februrary, 2023. By then, 36 total players had earned the badge[1]. The first player to obtain this badge was VinceHD_[8], and can be hovered over on his TETRA CHANNEL Userpage[4]. You may notice the timestamp being relatively recent; This is due to VinceHD_ having remade his account on the 12th of September of 2020.

10 All Clears

The badge awarded to any player who completes this challenge

The third of the "obtainable badges", this badge was added on the Second of June, 2020 alongside the 3.1.0 update[13]. To achieve it, one must clear ten All clears in one singular 40 Line sprint. Due to the very high level of skill this badge demands out of anyone looking to obtain it, this is the second most rarest of the badges one can obtain without moderator or admin intervention, followed only by the Number 1 badge. Unlike Jstris's "PC Mode", players are allowed above the fourth row without invalidating the run, allowing for possible DPC loop abuse if one is willing to both learn the loop and grind for "2 Line PCs". Due to the overall popularity of this badge, "Jstris PC mode world record holder and former Blitz world record holder"[14] JimothyJimothy made a specialized site with a specific section on it titled "10 PC Guide". The only things the game checks for when validating a run is simple:

  1. That it was a 40 Lines run.
  2. That the replay was verified and submitted to online servers.
  3. That the run was ended with more than or equal to 10 All Clears.

Note the lack of one pretty important requirement here: the run doesn't need to have an All Clear finish. If you can sneak one or two "2Line PCs" into your run, you can actually finish it with conventional 9-0 stacking as long as you have built up enough All Clears, meaning one single "2 Line PC" removes the need for one whole All Clear(the last one), or lets you buy some space with a "6 Line PC"

As of December 5, 2020, only 146 players taken the time and effort to get this badge[6]. Continuing onto March 7, 2022, only 743 players had gotten the badge by then[7]. The badge reached the 4-digit owners club some time around the 13th of February, 2023, where it was revealed that a little over 1,395 players had gotten the badge[1]. The first player to get this badge would be Caboozled_Pie[8]. His TETRA CHANNEL Userpage currently hosts the oldest "10 All Clears" badge[5].

KO'd Founder

The badge awarded to any player who completes this challenge

The exact date this badge was added is tough to nail down from the patchnote page alone as there is no release detailing a new secret aside from the previously covered badges. If the earliest instance's timestamp of this badge is to be believed, then this badge was added either with or after the 4.0.0 update released on June 22, 2020[15], and before or on the 25th of that month, as that is the oldest recorded instance of this badge[6]. This badge is quite self explanatory on how to achieve it. One must simply:

  1. KO osk, who incidentally happens to be the founder of TETR.IO[7], in any online mode once.
  2. The only qualifying user to KO is osk. You may not attain this badge by KO'ing Co-Founder Kagari.

A couple notes:

  1. It does not matter if the KO is an "Indirect KO", "Direct KO", or a "Spike KO". As long as you get credit for the kill, you will get the badge as well.
  2. If you happen to match up against osk in the Tetra League, you only need to take one round in your favor, not the entire set.
  3. osk themselves cannot obtain the badge by topping themself out through mashing the hard drop key right as a game begins. In such cases where a user tops-out without anyone sending them a single line of garbage, the "killer" is internally defined as "null". Therefore, if osk were to top themselves out, the system would attempt to award user "null" with the badge, and not user "osk".

The first challenge arises with catching osk online in the first place, as they usually stick to the dev servers/private testing with personal friends to test TETR.IO features out when they aren't developing TETR.IO in the first place. osk can usually be found in Quick Play after planned server maintenance for a few rounds. Supposedly, osk can be found in the many various, popular Twitch channels streaming TETR.IO at the moment watching and chatting along, and if the streamer runs a public custom room, then osk may pop in for a few rounds. If one is dedicated enough to keep an eye on the TETRA CHANNEL's Tetra News section or smart enough to hack together a sort of "push notification" with the TETRA CHANNEL API's "All Latest News" call, then they might overhear the notification of someone else getting the badge, creating a sort of "warning" that signifes osk activity. If the preliminary checks in public areas fail to find them, they may be online in the Tetra League, leaving for a possible "matchmaking snipe" if you are around osk's current "Tetra Rating" range, which is around rank S- as of writing(the 26th of December, 2020). Most, if not all, requests for 1v1's via Discord, Twitter, E-Mail, GitHub reports, Twitter, and messages through ingame chat are ignored.

Getting into a lobby with osk is half the battle. You must still KO them to get the badge. In the event that osk is in a 3+ player "Battle Royale" you might attempt to play the "targeting meta", meaning you mouse over every board to find osk's player board, then make the delicate decision between the four targeting modes. In the rare occasion that the host has the "Allow Manual Targeting" option set to "ON", simply click on osk's board to make them your manual target. After these preparations are complete, one might play the waiting game, keeping a close eye on osk's board with a prepared spike at the ready in the event that automatic targeting lands on osk's board. One might want to study a few "spike openers" openers such as the DT[8] or BT[9] cannons as a simple "Perfect Clear Opener" might not leave enough attack left over to counter garbage from other irrelevant players, and still have attack left over to hit osk with. One could ignore all this theorywork and simply play as normal, not worrying about the meta as it slows down their actual TETR.IO play with useless calculations.

As of December 5, 2020, 245 players have given osk a loss at least once since this badge has existed[6]. Continuing onto March 7, 2022, only 306 more badges were awarded, making a total of 551 badges[7]. This rate slowed into the 13th of February, 2023, where, as told by the founder himself, only 674 players total had received the badge[1]. The very first recorded occurrence of this badge lays on user swomp's player card[8]. You can also view it on her TETRA CHANNEL Userpage[10]. Several notable exemptions have been made to the above process of obtaining the badge. During the "closed testing" period of The Tetra League, where access was limited to supporters and users with the INFDEV badge, players perserved image proof of them KO'ing osk before this badge existed. Thanks to the images being relatively verifiable,(Nobody was really faking screenshots of them winning against osk in the TL back then. All images were posted months beforehand in unedited posts on the TETR.IO Discord server) a total of two notable cases of a moderator giving a player this badge manually, and both players hold a timestamp-less badge[2][3].

20 T-Spin Doubles

The badge awarded to any player who completes this challenge

The last of the "Solo badges" to have come out so far, this one was a semi-response to recent and persistent calls for a "20TSD" mode similar to the one found in Jstris. This badge was added on the Twenty-Eighth of September, 2020 with the announcement of a 5.0.0 update[16]. Very quickly afterwards, someone guessed the exact URL used for the 20TSD badge graphic due to how popular the request was at the time. The objective of this badge is very direct. Here's what'll get you a 20TSD badge:

  1. The mode played in must be 40 Lines.
  2. The replay must be verified and submitted to online servers.
  3. That the replay must end with 20 T-Spin Doubles and nothing else, meaning: if you clear 20 T-Spin doubles and a single T-Spin single/single line clear you won't get the badge.
    1. A "T-Spin Double" may be either a full or "Mini" line clear, and you may mix between the two so long as the final sum of both equals 20. E.G. 1 Mini T-Spin Double, plus 19 T-Spin Doubles, would still net you the badge.

Many players simply "cheese" this challenge with a setup known as a Mechanical T-Spin setup, which is a T-Spin setup with a 100% chance of getting you a T-Spin Double every 7-bag if you have a bit of opener luck. If you go this route, be warned that one cannot simply repeat the pattern to the top. You must "break" the pattern with two to four T-Spins remaining(many have luck with 3 T-Spin Doubles remaining, meaning the line counter reads "34/40"). Other popular methods include "LST Stacking" and plainly winging it and going full "freestyle" all the way to the top.

As of December 5, 2020, 449 players have spun their way to this badge[6]. Continuing onto March 7, 2022, 4,062 total players have attained the badge[7]. Holding 2nd place in terms of the most popular badge, around 7,595 players have the badge, assuming it's the 13th of February, 2023[1]. The first of those 7,595 would be RZA[8]. You can view the oldest badge of this variant on their TETRA CHANNEL Userpage.[17][18]

Super Lobby

The badge given to those who emerge victorious in a super lobby

This badge has quite the history associated with it, having its roots in Tetris 99. After the game's 2.0.0 update adding its Invictus mode in September 2019, Games Done Quick had a Tetris 99 portion in their GDQx 2019 event, where Hard Drop owner Blink would play a few rounds of Invictus mode, encouraging viewers on Twitch to snipe him live with their own copy of Tetris 99[19]. After this, notable player/streamer Tafokints wanted to gather all the top players into an Invictus room, where it would be easier for players to queue into the same room. This took place on October 26, 2019[20] in what would be the first official Super Lobby, although it wasn't called a Super Lobby until the following month, where Hard Drop announced that the Tetris 99 Super Lobbies would be a monthly event[21]. Later on, Hard Drop would eventually organize a TETR.IO Super Lobby, first during the Hard Drop Open XXI, and later on as its own standalone monthly event, which has a separate badge of its own for the winners.

The Hard Drop Super Lobby certainly brought in a demand for lots of optimizations regarding huge TETR.IO rooms, as many players were simply lagging out of these rooms due to a couple of reasons. Not soon after the first Hard Drop Super Lobby, which was canceled midway through for technical difficulties; "Super Lobby Mode" was revealed on the 5.2.2 patch[22]. It simply introduced a couple extra important animations and performance enhancements whenever any room had more than 100 players playing in it; nothing more. Enter in the 6.0.3 patch, which confirms this badge as being added on the 16th of March, 2021[23]. This makes it the second badge to have been directly named in the patchnotes, the first of which being the Number 1 badge.

Obtaining this badge isn't complicated. All one needs to do is be the final survivor in a match with more than 100 players playing; spectators don't count. It should be apparent if you're in a qualifying room due to the unique animations surrounding Super Lobby Mode, including rotating each board in a large "3d dome" like environment and the amount of players playing shown in a large cutin alongside special fanfare not normally played. A special system message will be published to room chat when a room reaches enough players to be a Super Lobby to all currently connected contenders and any future joiners.

The first player to officially emerge victorious in a generic TETR.IO Super Lobby was Caboozled_Pie, exactly one hour and thirty-five minutes after the announcement, made via the patchnotes, that such a badge was available.[24] As of March 7, 2022, up to 1,839 players have won at least one TETR.IO Super Lobby[7]. Despite its semi-recent release date, this badge is still the thirdmost popular with 2,572 owners, as of the 13th of Februrary, 2023[1].

KO'd by Founder

The badge awarded to any player who is KO'd by osk

Keeping true to its original namesake, this badge is extremely simple in concept and execution, yet relies on extraneous lobby conditions to receive. While theoretically more common than the opposite badge, since osk can KO multiple players in one game, it's far tougher to skew much luck in your favor when it comes to having osk target you. Because of this, and because of its extremely recent release date(releasing sometime on the 23rd of May, 2022), this badge is currently very rare. Attaining the badge is very straightforward. One must simply:

  1. Be KO'd by osk, who incidentally happens to be the founder of TETR.IO[11], in any online mode once.
  2. The only qualifying user to be KO'd by is osk. You may not attain this badge by being KO'd by Co-Founder Kagari.

A couple notes:

  1. It does not matter if the KO is an "Indirect KO", "Direct KO", or a "Spike KO". As long as osk gets credit for the kill, you will get the badge as well.
  2. If you happen to match up against osk in the Tetra League, he only needs to take one round in his favor, not the entire set.
  3. osk themselves cannot obtain the badge by topping themself out through mashing the hard drop key right as a game begins. In such cases where a user tops-out without anyone sending them a single line of garbage, the "killer" is internally defined as "null". Therefore, if osk were to top themselves out, the system wouldn't attempt to award anyone with the badge, since "osk" never KO'd anyone.

Getting into a lobby with osk is half the battle; more info on general strategy regarding this issue is detailed earlier in this page. Unfortunately, there's little known methods to "bait" osk into targeting yourself once ingame. It is unknown what osk targets for in a typical free-for-all match, so attempting to manipulate, say ELIMINATIONS targeting, by intentionally playing near the top of the field may be ill-advised due to unintentional top-outs from unrelated players. Since you're just trying to accept garbage from osk, one could potentially "stall" while scanning other boards for osk's username. Once located: hope for incoming garbage from that area, and if received, immediately top out, even if garbage does not directly top you out. Topping out under these terms will count as an "indirect KO", and should award the badge.

osk's ruthless kill count of 158 unique TETR.IO players, as of the 13th of Februrary, 2023[1], is confirmed. That makes a little over 3⁄5ths of a TETR.IO player knocked out per day.

"Exclusive Badges"

As with all the "obtainable badges", these "exclusive badges" follow most of the same rules as far as obtainable badges follow in terms of how they are layed out in a userpage or player card. from left to right, and in some cases, top to bottom. For the most part, these are standard badges that are notable for the fact that an administrator or moderator must add the badge manually from the admin panel.


A lot of these badges are simply given out based on the badgeholder's account age, though there are a few exceptions.


The badge exclusively given to osk
An image of osk in the quick play player list. They have a solid color tag similarly colored and designed as the Founder badge in place of a regular Verified checkmark.
In addition to the special graphics shown on the player list, osk also has an "admin green" playername, as well as the optional ability to make special "admin announcements" with that same shade of green.

This badge has existed since the beginning of TETR.IO, and is presumably the very first badge to exist. It signifies a simple fact: the badgeholder created the game you are looking at.

As of September 17, 2021, only 2 players have founded TETR.IO[1]. The first of which is osk, and you can view the badge on their userpage[12]. Interestingly enough, the INDEV and INFDEV badges are missing from osk's userpage+player card. The second badge holder is user Kagari; while the badge has the same Founder design, if hovered over, the tooltip will reveal the badge's text as "Co-Founded TETR.IO". You may view this special Co-Founder badge on her userpage[13].


The badge given to INDEV testers.

The INDEV development phase likely began on the 19th of February, 2019[25] and ran til the start of the INFDEV phase on January 31st, 2020[26]. During it, close friends would test TETR.IO privately while osk geared up for a more public release. It's highly likely this badge also existed before anyone had the Number 1 badge, however these badges lack a timestamp to confirm this assumption with.

As of February 13, 2023, there are 7 INDEV badgeholders[1]. Even though this badge was added to every INDEV tester at the same time, user gebruikersnaam[14] was likely the technical first due to his User ID[8].


The badge given to INFDEV testers.

Similar to the INDEV badge, this badge was given out to every account registered from the start of INFDEV at January 31st, 2020[26] to the end of INFDEV, and the enabling of fully public account creation, at March 22nd, 2020[27].

This is also the very first badge that gave the badgeholders special access to something non-INFDEV players couldn't access without paying for the supporter "role" on osk's patreon. Specifically, before the Tetra League was public for all to access, it was limited to players with the INFDEV badge and supporters.[28]. It would stay this way for two weeks, until the League was made available to the general public[29]

The INFDEV "logo" as seen on osk's blog post announcing the INFDEV development phase[26]

Another interesting fact stems from the blog post that started off this development phase. In it, there was already an INFDEV "logo" long before the badge was released, and even before players knew they were getting a badge in the first place. This logo would eventually be polished and end up the finished badge graphic. Going off some speculation, assuming we are to get an Alpha badge, we may already know the design of this badge from the Alpha blog post's "logo"[27]. Going even further off track, one can even assume the "phase colors" of the Beta and Release phases (being green and red accordingly), from this chart osk posted on the TETR.IO Discord server long before the alpha logo was announced[15].

As of February 13, 2023, there are 2126 former INFDEV testers with the badge[1], a curious extra 2 since the first badge values were revealed[6]. The technical first was, once again, user gebruikersnaam[16]. If you were looking for another account not created during INDEV, then you may be interested in user flash[17], as they were the technical first non INDEV tester to have the badge.


The badge given to user "animecake" exclusively.

The P.O.O.P. badge is an example of an inside joke left at its logical end. A simple search for "poop badge" on the TETR.IO Discord shows first public reference coming from moderator alcazar#0078 demanding a "POOP BADGE" for AmijoKaegger#8277 with a ping towards osk#9999 on the 14th of June, 2020. One day later, AmijoKaegger#8277, also known as animecake, would make the announcement that the poop badge had indeed arrived, then would follow up a day later with picture evidence of the badge in question, confirming its existence on the 16th of June, 2020 as the badge lacks a timestamp. The badge is actually an acronym, meaning:

  • Pioneer
  • Of
  • Our
  • Place

It was given to animecake for being the "first ever player on TETR.IO", as explained with hover text.

Only one person has obtained this badge, and its probably defined as an "Other badge" on the badge sheet[6]. It is exclusive to user animecake[18].

Huge Supporter

The badge given to huge supporters.

This badge began its existence sometime before the 4th of December, 2020[8], however was confirmed to have existed after user Zudo#0800 made a public request for ingame user Archina's information with Hiyajo Maho#2356's ">tetr" command on the TETR.IO Discord server. Zudo was a supporter at the time, so a rolling theory explains that osk may have tipped off supporters in the exclusive #supporter-lounge leading up to the very moment that command was utilized. None-the-less, it was given to user Archina[19] for an undefined amount of donations[8]. Archina was a supporter at the time, and is included in the special thanks of TETR.IO.

Arisa Ichigaya would have been the second known huge supporter, as they had the badge alongside Archina. This badge, unlike Archina's, came with a local news announcement, proving it came into existence on the 30th of December, 2020. The badge itself still lacked a timestamp, however. Unfortunately, Arisa Ichigaya would go on to recreate their account on the 18th of July, destroying the badge in the process. It is theorized image or video footage proof of the badge on this user exists, however, I could not find any screenshots in my limited search.

Starting December 25th, 2020, only one player had this badge. Most likely categorized as an "Other badge" on the badge list[6], the badge itself can be viewed on Archina's userpage[20]. Parallel to his userpage, beginning precisely on December 20th, 2021, top members on TETR.IO's special thanks section in the config, which is a list sorted by total amount spent on TETR.IO Supporter, also recieved it. As of writing, with this knowledge in hand, only three new badges exist in this form. You may view them on the userpages of either BARHO, RINSE, or ZUDO. These badges are added realtime, as soon as a member passes an as-of-yet unknown cutoff for total support, which is measured in TETR.IO's CONFIG. The latter of these members, user ZUDO, had confirmed that this cutoff at least surpasses €1,000(one thousand Euro). [30]

Early Supporter

The badge given to early supporters.

The Early Supporter badge was automatically awarded to every registered user who had subscribed to osk's Patreon page, regardless of amount donated, before the 6.0.0 update on the 31st of January[31]. This badge exists due to the platform switch osk underwent, swapping Patreon out for an ingame system backed by the oskVault, which, in turn, is powered by Xsolla as of writing[32]. Ingame rewards also recieved a price cut, so this badge adds a little bit more value to the prices supporters were paying before this switch. Specifically, the "Deca tier" costed 10 Euros a month, but now, the ingame rewards only cost 5 Pounds a month. (or 4 Pounds a month if you end up buying in bulk, or gifting to another user)

The badge itself is modeled to resemble the Greek symbol, as Patreon was used and subsequently ditched during TETR.IO's Alpha period.

As of February 13th, 2023, 354 users hold this badge[1]. It is likely user gebruikersnaam was the technical first, and the badge can be viewed on his userpage[21].

Bug Bounty

The "bounty" itself, awarded to players who responsibly report vital issues.

This badge is TETR.IO's cost effective way of rewarding players who do two very important things in order:

  1. Find a harmful bug in TETR.IO which may be abused by possible bad actors. Such exploits may involve a form of "arbitrary code execution", which would, for example, allow a bad actor to run code on a target's machine to gain unauthorized access to their TETR.IO account. Another example would be sending maliciously created data to the TETR.IO servers, rendering all connected clients softlocked/crashed or the TETR.IO server itself temporarily offline.
  2. Responsibly report this exploit directly to osk through the appropriate communication channels, without abusing the reported issue for personal gain. As listed on https://tetr.io/about/support/, these lines of communication are 100% private, as to not publicise potential exploits others may abuse.

Historically, of the few users to have obtained this badge, several additional perks have followed the badge decoration. While these may not be absolutely assured, the perks are as follows:

  1. A variable duration of ingame TETR.IO Supporter, free of charge, gifted by osk himself.
  • For a real life example, according to Discord user "Тhе buttег mаn bоbi#4190", the pay for his found exploits totaled up to 3 years of supporter![33] For context, TETR.IO Supporter is valued at 4 Euros per month so long as it's being gifted. This means BOBI got €144 worth of Supporter.
  1. The exclusive "Contributor" role on the TETR.IO Discord server.[33]

Evidently, these special gamebreaking bugs do not show up often in TETR.IO. The bounty badge itself was only added on the 27th of June, 2021, however the badge was retroactively given to user SZY for reporting an exploit during the INFDEV, far before this badge existed. At least seven known users hold this bounty. In sequence, these users are BOBS, SZY, MANABENDER, KAMINARI14, ZUDO, AZURAHORIZONS, and OPYUWUWU.

This section will go into detail regarding TETR.IO's many officially partnered third party tournaments, which contain badges for the top three placements as well as an additional badge for the winner of certain Twitch chat participation campaigns when applicable. As of writing, TETR.IO has partnered with many distinct tournament organizers with many more separate badges. Many of these tournaments ran, and continue to run, several tournaments, meaning several people hold badges for placing first in an "Underdogs Cup" tournament, for instance.

Over 525 "Event badges" have been awarded, as of February 13th, 2023[1].

Garbo Gamble Cup

From left to right, the badges awarded for placing #2nd, #1st, #3rd, and the badge for the winning Gambler of the Garbo Gamble Cup.

The "Garbo Gamble Cup" was the very first partnered TETR.IO tourney, and with it, brought four exclusive badges for the top three players to emerge from the tourney, as well as an extra badge for the Twitch user to win the "Gambling Competition". It was announced on the 2nd of June, 2020 and took place on the 7th later that month[34]. The tourney featured 132 players [35] and took place over nearly five hours. The replay of the Tournement can be viewed on garbocan_'s Twitch channel, split up into two parts[22][23]. The first part is spent largely fixing technical issues with the Twitch bot GGC staff utilized. The first match can be viewed nearly twenty-two minutes in[24].

The actual games would take place in 2 player custom rooms, with default settings. The selected format was a simple "First to 7 points wins the set.", and every player is allowed to lose up to two sets before being eliminated entirely. This is a well known format known as double elimination and is the norm for most, if not all, TETR.IO tourneys.

Over the course of the tournament, a free betting game was played by players in Twitch chat. Every user in Twitch chat would start with 1000 "chips" free of charge, then, when a two player 1v1 match would begin, players would "bet" their chips on who would win for either a payout or a loss depending on who actually ends up winning. Their bet chips are multiplied by a variable factor decided by how many chips are bet on the opposing player- the "odds" of a player winning- if the bet happens to be correct, and is then added directly to that user's chip balance. If the bet is incorrect and the other player ends up with a victory, the player who bet simply loses their bet chips. In the event that a player ends up "bankrupt", that is, they bet every chip and end up with a flat value of zero chips, a "Welfare Check" worth 100 chips is payed out to the bankrupt user, allowing them to continue making bets from the brink of financial crisis.

There was only one Garbo Gamble Cup hosted, and the stream lacks any indication towards a second one. As such, only four badges for this tourney exist, and of those four, one has been destroyed. The top three, and the gambling champion, would receive badges as well as prize money, as shown below:

An image of the announcement garbo made in the fourwi.de Discord server above an archived photo of caboozledpie's player card at the time.
  1. ajanba: 619.93$ in cash, as well as the First Place badge for that tourney. Later on, ajanba would delete his account, thus destroying the GGC #1 badge. However, the badge graphic is still hosted on TETR.IO[25].
  2. rideris: 247.90$ in cash, as well as the Second Place badge for that tourney. It can be viewed on their userpage[26].
  3. qmk: 123.98$ in cash, as well as the Third Place badge for that tourney. The badge can be viewed on their userpage[27].
  • realkokon: 175$ in cash(down from the technical 247.90$ he should have won. realkokon declined the full sum and let garbo keep 72.90$) and the Gambling Champion badge. You can view the badge on his userpage[28]

Notably, realkokon had biological ties to another TETR.IO player who had actually competed in the Garbo Gamble Cup, but had been eliminated long before the tourney ended. Specifically, realkokon is user "Caboozled_Pie"'s father, and realkokon passed down the badge to his son, named caboozledpie ingame at the time, for a short period of time after the tourney had ended. Seemingly days later, realkokon made an ingame account named "kokon" and the badge was transferred over, due to the small issue with a competitor having a badge he didn't exactly deserve.

WPL Tetr.io Open

From left to right, the badges awarded for placing #2nd, #1st, #3rd, in the World Puzzle League.

Despite actually predating the Garbo Gamble Cup, being established on the 12th of April, 2020, the WPL Tetr.io Open wouldn't receive special badges for the top three placements until their 5th TETR.IO tourney announced on the 8th of June, 2020[36], and hosted on the 13th of that same month[37]. A recap of the final set played on that tourney is available from the official World Puzzle League YouTube channel[29].

All matches were played in custom 1v1 rooms with most of the stock settings, aside from "Gravity Margin Time" beginning far later, specifically changing that value to 7200 from 3600, and having it affect gravity much more, specifically changing that value to 0.0035 instead of 0.0025. This was "done to mirror Tetra League settings."[37]. The tournament was largely played with the "First To 7" goal, however for the Winners Semifinals, Losers Quarterfinals, and any match played these two it would be a "First To 11" match. This tourney would also be played in a "Double Elimination" format, and features 174 contestants in total. Of those 174, here are the top three:

  1. ajanba: First Place. Once again, ajanba would go on to delete his account after obtaining this badge, thus destroying the badge in the process. However, since the WPL is a reoccurring tournament, there are plenty of more people with the WPL #1 badge.
  2. qmk: Second Place[30].
  3. KABUTOMUSIAAAAA/gamaover, otherwise known as Kazu: Third Place[31].

It is interesting to note that the two badges linked to above do in fact contain timestamps. This is notable due to the fact that many other "tournament badges" lack timestamps. Even First Place badges from this same organization lack them!

On the 3rd of June, 2020, the 6th WPL TETR.IO tourney would be played[38]. A recap of the grand finals can be viewed from the official WPL YouTube channel[32]. It too, would have the same settings as its predecessor played last month. 154 players would compete; the top three are listed below:

  1. FireStorm: First Place[33].
  2. qmk: Second Place[34]. As a repeat second place win, qmk would keep their 2nd place badge from the last tourney, as proven by the timestamp included.
  3. puyodialgao7, otherwise known as Diao: Third Place. This account was also deleted for whatever reason some time after this match was played.

Later that month, on the 18th, the 7th WPL Open would be played[39]. It features the same ruleset as the 5th and 6th WPL's played just weeks before. Like the others, you can view a recap of this tourney's grand finals on the WPL YouTube channel[35]. Only 126 players would show up this time, and from those 126, there would be three victors:

  1. FireStorm: First Place[36]. A repeat, so there's no new badge here
  2. cz0402: Second Place[37].
  3. qmk: Third Place[38]. qmk placed lower than 2nd this time around, so new badge here either

Later, on the 15th of August, 2020, the 8th WPL for TETR.IO would take place[40]. At a glance, this tournament copies the ruleset of the previously defined tourneys, however it includes a direction to turn off the "Scale Garbage Travel Speed" option. At the time, osk was running a test with differing garbage speeds[41]. Later on, osk would remove the feature[42]. Back on track, you can view this tourney's grand finals on the WPL YouTube[39]. This tourney would have 147 contestants fighting for glory, and quite possibly, money. Of those 147, these three would win:

  1. ningcha, once again credited as Diao: First Place. This is the second account credited as being "Diao" in the results annoucements that has been deleted.
  2. cz0402: Second Place[40]. This would be the second time cz obtained second place, and as such it is a duplicate badge that wasn't awarded.
  3. FireStorm: Third Place[41]. FireStorm already had the first place badge, so they didn't replace it with a badge of a lower tier here.

A little later, on the 19th of September, 2020, the 9th WPL would be hosted[43]. You know the deal now, same settings as last time, and as usual there's a video recap of the grand finals from the WPL YouTube channel[42]. Out of 150 players in this tourney, here are the three most important ones:

  1. majimedewanai, once again credited as Diao: First place. Yet again, Diao would go on to delete this account, like many others, trashing the special badge with it.
  2. qmk: Second Place[43]. A repeat of the first time qmk got 2nd place many months ago. Their badge is still timestamped from that tourney
  3. ZeroT: Third Place[44].

Finally, on the 23rd of October, 2020, the 10th, for now at least, the last WPL was hosted[44]. It features one neat addition to the rulebook, imposing a "First To 11 and Win By 2" on the Winners Semifinals and Losers Quarterfinals and on every other match played after. Another recap of the grand finals was uploaded to the WPL YouTube channel[45]. Out of 164 total players, here are your top three:

  1. cz0402: First Place[46]. This "upgrades" his Second Place badge into a First Place one.
  2. FireStorm: Second Place[47]. As he already had the First Place badge, no new badge was given out here either.
  3. PekoDialga0, otherwise known as Diao: Third Place. As said before, account PekoDialga0 doesn't quite exist anymore, as the account was deleted.

Hard Drop Open XII

From left to right, the badges awarded for placing #2nd, #1st, #3rd, in the Hard Drop Open XII.

This tourney was the twelfth in the long running "Hard Drop Open" series of tournements which started in July 19th, 2009 as a tournement hosted on the Blockbox fangame[45]. On June the Ninth, 2020, the "Hard Drop Open XII" event would be announced via Twitter[46]. It would be another double elimination tourney hosted on the 20th later that month, featuring entirely default settings and a First To 7 format during the earlier rounds, and a First To 10 format during, and after, the Round 5 upper bracket and Round 7 lower bracket[47]. If you're interested in viewing a recap of the tourney hosted live on Twitch, you can obtain such a thing from Hard Drop's official Twitch channel[48]. A total of 256 players would attend this event. Of them, here are the top three who earned special badges for accomplishing such a feat:

  1. Calcu1ation: First Place[49].
  2. FireStorm: Second Place[50].
  3. qmk: Third Place[51].

This tournement would also feature a "Special Event", which ended up being a "Super Lobby", such as the ones previously hosted by the same organization on Tetris 99. It was entirely open to the public watching the stream, as the room itself was actually "private" ingame with the direct link and room ID being shared through Twitch chat. 168 players would join the room, but due to server constraints and no optimised system in place for such huge rooms, 42 people would disconnect before the game even started leaving 126 players to battle it out. Of them, jason0107 would win the room alongside a cash prize of 100$. There was a badge graphic created for winning this room and it was touted as a possible reward for winning on the Hard Drop Discord server, but it was never added to jason0107's TETR.IO profile due to an oversight from either Blink, the founder of Hard Drop, or osk, the guy in charge of adding the badge in the first place. A replay of this special lobby can be found on the same VOD as the tourney itself, six hours and twenty-five minutes in[52].

Infinite Finesse

The first Infinite Finesse tournament to give out badges was Infinite Finesse IV (also known as Infinite Finesse: Passthrough, or just IFT (tournament)) on October 17, 2021, the fourth tournament in a running series of tournaments by Nysdey and Keshy. The Infinite Finesse tournaments mainly feature various gimmicks or formats other than the standard 1v1, such as teams formats or joining a team to give one side in Grand Finals an advantage by a score handicap.

Super Streamer Lobby

The Super Streamer Lobby badge was obtained by winning once in the lobby. Same event that took place on Saturday, December 2, 2023 on wyliecanttwitch's Twitch channel being this host it was an event where he what was sought was to bring together the community of Tetrio creators. The Wumbo player was the first to obtain this badge.

Santa Lobby

The Santa Lobby badge was obtained by winning a game once. This event took place on Saturday, December 23, 2023 on the HardDrop Twitch channel, hosting blink, a Christmas event to share the magic of Christmas. The Gyozan player was the first to obtain this badge.
