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:

..........

...G..SS..

...GIIII.J

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:
