Tetris The Absolute The Grand Master 2[a] (also known as T.A., and TGM2) is Arika's second title in the TGM series. It is an arcade game published by Psikyo in October 2000. The Grand Master 2 introduced the less-intimidating Normal mode to attract more casual gamers, as well as an all-new grading system in Master mode, the continuation of TGM's original gameplay.

Two months later in the same year, a free upgrade of the game, titled Tetris The Absolute The Grand Master 2 PLUS (also known as TAP, and TGM2) was released, which added TGM+, T.A. Death, and increased the GM requirements for Master mode. It is very rare to find a The Grand Master 2 arcade PCB that has not been updated to the PLUS version.

Gameplay

Sonic lock

Sonic lock, a hard drop that doesn't lock, was added to the base TGM gameplay, which improves low gravity gameplay by allowing Zangi-moves.

Buffer zone

Above the playfield, the game uses a single-row buffer zone, effectively extending the height of the playfield from 20 to 21. Row 21 allows blocks that lock in it to reappear once the stack is lowered. Any row above it, however, is not part of the buffer zone, meaning that blocks that lock in such rows get deleted and will not reappear once the stack is lowered.

Game modes

Normal

Normal mode plays similarly to Master mode in gravity and speed timings, but ends at level 300. At levels 100 and 200 an item block is given to the player. "Free Fall," which eliminates all holes, is given at 100. "Del Even," which clears every other row throughout the field is given at 200. The credit roll challenge is a slow 20g, but playing through it is not required for a "Clear". See scoring bellow for how score is calculated in this mode.

Speed timings

The unit for gravity is G (rows per frame), as a fraction with a constant denominator of 256. This means G = Internal Gravity/256. For example, at levels 90 through 99, the gravity is 64/256G, or 1/4G.

Master

Master mode is Arika's evolution of the original Tetris The Grand Master gameplay. In TGM the speed timings remain the same for the entire length of the game. New to The Absolute is shrinking delays that speed up the game after level 500. The length of the game remains the same, with players trying to complete 999 levels.

Line ARE defines the number of frames of ARE to use after a line clear. The player's DAS charge is unmodified during line clear delay, the first frame of "lock flash" that occurs during the beginning of ARE without a line clear, and one frame of level-increment delay a little before the next piece spawns, and the frame a piece spawns.

Grade Recognition System

Main article: Grade Recognition System

A new version of GRS (Grade Recognition System) was developed for The Absolute. This time, instead of the player's score, their speed and skill are taken into account. Additionally, the GM grade requirements have been expanded, including Tetris line clear requirements, faster completion time, and an invisible credit roll challenge, which is called the M-Roll.

In The Absolute, grades go from 9–1, S1–S9, M, GM.

Credit roll

See also: Grade Recognition System#Credit roll

If a player completes 999 levels, the playfield is cleared, and a new challenge starts, with the credits rolling behind the stack. There are two credit rolls in The Absolute Plus, the Fading Roll, and the M-Roll. The Fading Roll is a 1 minute challenge, where pieces in the stack will fade out four seconds after locking. If a player clears the Fading Roll, their rank will be underlined with an orange line, which ranks above green lines, or players who did not clear the Fading Roll with the same grade, regardless of completion time.

If the player unlocks the M-Roll, they are met with an invisible challenge. Pieces turn invisible as soon as they lock down. If the player fails to clear, they are awarded the M grade. If the player clears the M-Roll with less than 32 line clears, they are awarded a Green line GM grade. Surviving the M-Roll with 32 or more line clears will award the player an Orange line GM, the highest possible grade.

TGM+ is a rising garbage mode, similar to Sega's Bloxeed. Players must dig through to survive as they progress through the 999 levels. This mode has speed timings similar to TGM. An internal counter is incremented every time a tetromino is locked down without clearing lines; once this counter reaches , a row of garbage rises from the floor of the playfield, and the counter resets.[d] The garbage follows the fixed pattern shown here, looping every 24 rows.

Unlike other modes, TGM+ has no grades, medals, or ranking. A credit roll is played upon reaching level 999, but similarly to TGM, it is not neccessary to survive the credit roll. After the credit roll, a message "Excellent!" is displayed.

Gravity is the same as Master mode, while speed timings are the same as Normal mode.

T.A. Death

In T.A. Death, gravity is fixed at 20G for the entirety of the game. Combined with increased speed timings, it is one of the most difficult modes to complete in the series.

A video originally titled "Death 800", features a player breaking level 800, went viral under the name "Tetris Japan Finals". This video created widespread knowledge of the game, and is responsible for introducing many of the first Western players to the series.[2]

Ranking

Only two grades are achievable: M and Gm. The conditions are:

  • The player must reach level 500 under (or equal to) 3:25:00, the M grade is given and the game will continue to 999.
  • Gm is awarded at 999 regardless of time or score. The game continues through the credits, with no effect when playing on or blocking out.

Because of a torikan, if the player reaches level 500 with a time greater than 3:25:00, the timer will stop and the credits will roll. The player is given an "Excellent!" but no grade.

Speed timings

Though Death mode has a fixed gravity of 20G, there are 4 other timings that shape the flow and speed of play.

400 8 8 8 18 6
401 - 499 7 7 8 15 5
500 - 999 6 6 8 15 4

As a result of these timings, there is no time penalty for clearing singles instead of Tetrises from level 100–299. As these values decrease, the options for piece placement gradually reduce, becoming a subset of what was once possible in regular 20G.

Doubles

Doubles is a two player cooperative mode that puts both players in one well that is 14 units wide instead of 10. In TAP, it is selectable from the menu. In The Grand Master 2, it was accessed one player holding down the start button on their side while the other player pressed the other start button to join in. In TAP, one credit pays for both players.

Each player has a separate level counter and lines they clear are only added to their level. Both players must reach level 300 to complete the game. Like in Normal, there are no level stops at 99 or 199, but each player must clear a line to go from 299 to 300. Whichever player reaches 300 first enters the credit roll speed of 20G until the other player also reaches 300, at which point the timer stops and the credits start. It is quite difficult to survive for long in 20G with such a wide well, so winning requires a fine degree of coordination between the players so that they both clear a line to advance to 300 at nearly the same time. Also like Normal, the credit roll can be fast-forwarded by holding down Start, and surviving it does not matter; the score is awarded a green line regardless.

Doubles has some bugs regarding input handling which can result in one player's DAS being instantly charged or their inputs being ignored. These are not currently fully understood, but seem to have to do with inputs that occur on the same frame that one's partner clears a line. There is also odd-looking behavior which could be considered a bug when one player places a piece on top of the other player's piece which clears a line.

Versus

See also: Tetris The Grand Master#Vs. Mode
See also: TGM Versus Mode Guide

The versus mode in The Absolute works in a very much like its predecessor, The Grand Master. Each player plays in their own playfield. Clearing two or more lines will cause garbage lines to be sent to the bottom of their opponent's playfield. Unlike garbage in other Tetris games, the garbage holes correspond to the location of the line clearing piece. This means that the usual playing style of the series, of leaving a column down the right for Tetrises is not as beneficial, because if both players do it then any garbage sent will line up with the opponent's Tetris hole. Alternating sides, or using other pieces to clear lines will send garbage that is more difficult to the opponent to clear. Versus mode in Bloxeed and DuelTris worked similarly.

All of the four single player modes can be played in Versus mode, although a Normal mode game will be temporarily converted to Master for the duration of the match, signified by the playfield frame changing from grey stone to grey metal. Normal, Master and Death use their respective speed curves for each player. TGM+ mode has garbage rising automatically from the bottom, in the same way it does on single-player.

To start a versus match, either player picks a mode, and starts as if playing alone. When the second player pushes their respective start button (assuming there is a credit) they will be asked if they want to challenge the other player. If they choose 'yes', then the other player will lose their game, "Here comes a new challenger" will scroll across the screen, and versus mode will start in whatever mode the first player was playing in. To prevent unwanted versus games, the first player can press their start button, which will cause "No more challenger" to display on the opposite field. Pressing the start button again cancels this effect. If a second player starts while "No more challenger" is displayed, then it will skip the challenge menu and go straight to the mode select.

For versus the default target level is 200, and time limit of 2:40:00. The target level can be changed in the game setup (in 100 level increments), with the time increasing or decreasing by 1:20:00 for every 100 levels. If a player tops out their field, then they lose. If neither player tops out their field in the allocated time limit, then the winner is the player with the highest level. If a player reaches the target level then the game ends and they are declared the winner. By default, the overall winner is the first player to win two games, but this can be changed in the game setup.

Items can be turned off by each player holding their respective start buttons as Versus mode is initiated. If A+B is also held down on both players, garbage is also turned off completely, activating what the game calls "Cement mode."

Items

Each player has a green bar to the side of their field. With each piece placement, this bar increases slightly. When the bar is filled, after placing 20 pieces, the next piece the player receives will be an item piece. The shape of the piece is retained, but the appearance of the individual composite blocks will be different, depending on the item. The piece is placed normally, and the item is used automatically when a line containing part of the item piece is cleared. Bloxeed was the inspiration for items,[citation needed] which many of the powerups, like the 16 ton weight, and delete even where the basis of items in The Absolute. Unlike Bloxeed, DuelTris, and Tetris DS, the entire piece counts as the item, instead of only one block of it.

Pieces are chosen using a bag system, with each item having their own weight. Items with a heavier weight are less likely to be chosen first, and is generally why "Dark" is the last item to be dealt in the bag. Once the bag is depleted, it is repeated a second time.

Most of the items from The Grand Master are reused. SPIN FIELD and PRESS FIELD were removed, and COLOR BLOCK, DARK BLOCK, and MIRROR BLOCK were added.

Attack items
DEATH BLOCK Makes the opponent's next block big.
NEGA FIELD Flip the playfield's occupied cells to empty, and empty cells to occupied.
180° FIELD Rotate the playfield upside down and move the newly rotated cells down.
SHOT GUN! Randomly shoot a group of holes in the opponent's stack.
HARD BLOCK The opponent's next piece must be cleared twice to be removed from the playfield.
LASER BLOCK Remove a column of holes in the opponent's stack. The attacker many move the laser by pressing left and right.
ROLL ROLL The opponent's next 3 pieces are auto rotating by a fixed interval.
TRANS FORM The opponent's next 3 pieces will change tetromino every time the piece is rotated.
X-RAY A partially invisible effect is applied to the opponent's stack for a short period.
COLOR BLOCK A partially invisible effect is applied to the opponent's stack for a very short period.
DARK BLOCK Stack becomes fully invisible for a medium period.
MIRROR BLOCK The opponent's stack is mirrored 3 times for each new piece, leaving it mirrored after the 3rd piece.
Defense items
↑ DEL FIELD Deletes the upper half of the player's playfield.
↓ DEL FIELD Deletes the lower half of the player's playfield.
→ MOV FIELD Push every cell in the player's playfield to the right.
← MOV FIELD Push every cell in the player's playfield to the left.
DEL EVEN Deletes every 2nd row in the player's playfield.
Special items
FREE FALL Forces all cells to move down in the player's playfield removing any holes.
EXCHG FIELD Swaps the player's and opponent's playfield.

Scoring

Like TGM, points are only awarded when the player completes line clears. A bonus for using sonic drop is new to the scoring formula. The Absolute Plus also changes the scoring system, adding a reward for fast play among other changes. The formulas are:

TA:
TAP:

Where:

  • is the ceiling function (i.e. the contents are rounded up).
  • Level is the level just before the line clear.
  • Lines is the number of lines you just cleared.
  • Level After Clear is is the level just after the line clear. This is different from for edge cases like reaching 300 in Normal mode, 500 when being torikan-stopped in Death mode, and reaching 999 otherwise.
  • Soft is the cumulative number of frames during which Down was held during the piece's active time. Note that this means manually locking pieces already on the ground will increase the Soft value by 1.
  • Sonic is the number of rows covered by the single greatest sonic drop during the piece's active time. Note that this is non-cumulative.
  • If the previous piece cleared no lines, Combo is reset to 1. This calculation is done before the score calculation:
    Example: A double-triple-single combo will have combo values 3, 7, and 7 respectively.
  • Bravo is equal to 4 if this line clear resulted in a perfect clear, otherwise it is 1.
  • Speed can be no less than 0, and is otherwise equal to:
    where Lock Delay is the number of frames of lock delay given out for that particular level, and Active Time is the number of frames the piece was active (which is a minimum of 1).

Normal mode multiplies line clear scores by 6 and the player is given a time bonus of where Seconds is the clear time in seconds.

Development

Changes between TA and TAP

  • M-Roll conditions have been changed. Notably, the section time conditions have been altered and the required Tetrises per section have been increased for for the first 5 sections.
  • Two new modes have been added, TGM+ and T.A. Death.
  • Scoring formula has been changed, adding an extra term for the level after the line clear and another for placement speed.
  • The method for accessing Doubles has changed and it is selectable from the mode select screen.

Codes

Item mode

When selecting either Master or TGM+ mode, hold B and C, then press Start while "READY" is still on-screen. If the code was correctly entered, the "NEXT" text will pulsate when the game starts. This code causes item pieces to appear like in 2-player versus mode, except all effects from items are sent to yourself.

Title screen codes

The following codes should be entered on the title screen, and only take effect in Normal mode and Master mode. Using them disqualifies the score from appearing in the rankings.

Name Code Effect
20G Mode DDDDDDDDCBA Forces maximum gravity.
Big Mode LLLLDCBA Tetrominoes are twice their normal size, simulating a 10 × 5 well.
TLS Mode ABCCBAACB The ghost piece always appears throughout the game.
Key: L = Left, D = Down, U = Up, R = Right

Emulation

The tables below provide verified lists of archives and files to make sure that Tetris the Absolute the Grand Master 2 and/or Tetris the Absolute the Grand Master 2 Plus can be emulated properly. There aren't any guides, at this point, for dumping these required files from the PCBs; but these files can be searched out on the Internet.
