I-Spins in SRS
Different rotation systems that approximate SRS apply different wall kicks and floor kicks when the player twists the I tetromino.
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 |
However, an extra block impedes the choice of the upward kick position:
|
Rotated right |
Soft dropped |
Rotated left |
The following can be performed instead, at least 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 |
