Tetris 99 is a game released through the Nintendo Switch Online service, based around battle royale-style play.
The game currently contains a single mode, Tetris 99. In this mode, the aim is to survive as long as possible among all 99 players.
The mode is garbage-based, with the player being able to send garbage to other players.
The player can earn badges from knocking out other players. Collecting badges will increase the player's attack power.
As players get knocked out, the piece falling speed increases, eventually reaching 1G when there are 5 players remaining.
|Badge number||Attack boost||Required||Total|
The game's base garbage table is consistent with most guideline games, with the exception of the All Clear bonus.
|Line clear||Lines sent|
|Mini T-Spin Single||0|
|Mini T-Spin Double||1|
|All Clear bonus||+4|
The game counts combos starting from the second consecutive line clear (as 1).
If the player is targeted by multiple opponents then they will receive a boost to attack power for each clear:
|Opponents||Bonus lines sent|
This boost is applied before the badge attack boost.
The game provides four automatic targeting modes:
- Badges: Target opponents with many badges.
- KOs: Target opponents who are close to being knocked out.
- Attackers: Target opponents who are targeting the player.
- Randoms: Target opponents at random.
Alternatively, the player can also switch targets manually.
