Different rotation systems that approximate SRS apply different wall kicks and floor kicks when the player twists the I tetromino.

Guideline SRS

Games such as Tetris Worlds and Tetris DS are based on the Tetris Guideline, including SRS. They have the following behavior:

..........
...IIII...

...G..SS..
...G.SSJJJ

Soft dropped

...G.SSJJJ
...GIIII.J

Rotated right

But the wall kicks are not symmetric, as the kick up is performed in preference to the kick down when rotating left:
