From Hard Drop Tetris Wiki
Different games that use SRS apply different wall kicks and floor kicks when the player twists the I tetromino. SRS in TGMA is partially symmetric, fully symmetric in TGM3 and Tetris Perfect/Tetris Return.
Official SRS
Tetris Worlds, Tetris DS and Tetris The Grand Master Ace are based on the Tetris Guideline, including SRS. They have the following behavior:
|
Rotated left |
Soft dropped |
Rotated right |
But the wall kicks are not symmetric, as Tetris Worlds, Tetris Deluxe, Tetris DS and Tetris The Grand Master Ace prefer to kick up rather than down when rotating left...
|
Rotated right |
Soft dropped |
Rotated left |
...unless there is another block to force a kick down:
|
Rotated right |
Soft dropped |
Rotated left |
The following can be performed instead. This is a well-known cheat in Tetris DS.
|
Rotated left |
Moved right |
Soft dropped |
Rotated left |
Tetris Advance
Minna no Soft Series: Tetris Advance, while implementing SRS, included several bugs including the lack of some wall kicks.
|
Rotated left |
Soft dropped, can't rotate right |
Lockjaw
In Lockjaw, both left and right prefer to kick down rather than up when rotating:
|
Rotated right |
Soft dropped |
Rotated left |
Arika SRS
Arika SRS (used in TGM3 and Tetris Perfect/Tetris Return's SRS) always prefers to kick up. This is very bad for some setups.
Tetris Best/Perfect/Return
Tetris Best, Tetris Perfect and its mods use a custom symmetrical rotation system that always prefers to kick down than up, so the problem is solved. Also, the additional kicks not in SRS make it possible to make I-spin Tetris:
|
Rotated right |
In Tetris Best, this is the extreme kick, so this setup is needed. In Tetris Perfect and mods, it may be displaced up+right due to 3-kicks. It may also be displayed one more row up due to force rotation (which allows 4-kicks).
