Twists let a player fix some otherwise difficult situations. These examples cover recent games, but some of them may not work for earlier Tetris games that use little or no wall kick.

Two algorithms, with slight variations, have been used in newer games to detect and reward in-place spins:

  • In The New Tetris, a T-spin bonus is awarded if a tetromino locks in a position where it cannot move left, right, or up.
  • In Tetris DS (and possibly other SRS based games), a T-spin bonus is awarded if all of the following are true:[1]
    1. Tetromino being locked is T.
    2. Last successful movement of the tetromino was a rotate, as opposed to sideways movement, downward movement, or falling due to gravity. (Canceling lock delay in games that allow it, such as Tetris DS, does not count as a movement.) The tetromino doesn't even have to end up in a different orientation than it was dropped in; setting up the "well-known twist" below in Tetris Worlds or Tetris DS and pressing both rotate buttons (B–A or A–B) will trigger the T-spin bonus even without any net rotation.
    3. Three of the 4 squares diagonally adjacent to the T's center are occupied. (In Tetris DS, the walls and floor surrounding the playfield are considered "occupied", while in Tetris Worlds for GBA, they aren't.)

Twists with T (or T-Spin)

A well-known twist involves the tetromino T.

ggggttggg
gggggtgggg
gg
ggggtttggg
gggggtgggg

Other variants exist, especially in games that use some form of wall kick. For example, the following works in TGM rotation and in SRS, but it is not scored as a T-spin in Tetris Worlds if performed on the floor of the playfield.

tgggg
ggggttgggg
gggtgggg
gggg
ggggtgggg
gggtttgggg

This example from SRS is not strictly a twist, as the tetromino could have been rotated before being dropped, but SRS games count it anyway:

gt
ggggggtttg
ggggggggg
gt
ggggggttg
ggggggtggg

This one is a T-spin in Tetris DS but not Tetris Worlds due to the difference in how the playfield walls are handled:

tg
tttggggggg
ggggggggg
tg
ttggggggg
tggggggggg

Triples may not seem possible, but especially games using SRS will allow them regardless. Notice that the ending position of the T tetromino does not overlap the starting position.

Twists with I

If changing position to the second row, rotate three times so to twist on lower-middle square.

ggggiggggg
gggiggg
ggggiggggg
ggggiggggg
ggggggggg
gggiiiiggg
ggggggggg
ggggggggg

If changing positions to the right columns, turn right. If left, turn left.

In SRS, I tetrominoes can be rotated on their end blocks:

i
gig
ggggiggggg
ggggigg
gg
ggggggggg
ggggiiiigg

Twists with S and Z

If using S, rotate right. If using Z, rotate left.

sggggg
gggssgggg
gggsggggg
ggggg
gggssgggg
gggssggggg
s
ssggggg
ggggsgggg

SRS only:

zzgg
zzg
ggggggggg

ggggggggg

gggggzgggg
ggggzzgggg
ggggzggggg
ggss
gss
ggggggggg
gggggggg
ggggggggg
gg
g
ggggsggggg
ggggssgggg
gggggsgggg

In this case, if using S, turn left and if using Z, turn right.

Twists with J and L

Works in virtually all versions, including Tetris (Game Boy):

LGGGGG
GGGLGGGG
GGGLLGGGG
GGGGG
GGGLLLGGGG
GGGLGGGG

Works with TGM and SRS:

jj
gggjgggggg
gggjgggg

Works with TGM and TDS only, excluding games using older versions of SRS:

ggllg
ggglg
gggglggg
ggggggggg

gggglllggg

Like other spin triples, this works with SRS only:
