cogetgettro 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:

iiii
gss
gssjjj
gj
i
i
i
i
gss
gssjjj

Rotated left

i
giss
gissjjj
gij

Soft dropped

gss
gssjjj
giiiij

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:

iiii
zzt
lllzztt
lt
i
i
i
i
zzt
lllzztt
lt

Rotated right

i
zzit
lllzzitt
lit

Soft dropped

iiii
zzt
lllzztt
lt

Rotated left

However, an extra block impedes the choice of the upward kick position:

iiii

Lockjaw

In Lockjaw, both left and right prefer to kick down rather than up when rotating:
