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 have been used in newer games to detect 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 command was a rotate or (in Tetris DS) a rotate followed by a lock delay cancel (Up or Down).
    3. Three of the 4 squares diagonally adjacent to the T's center are occupied.

In fact, in Tetris DS, setting up the "well-known twist" below and pressing both rotate buttons (B–A or A–B) will trigger the T-spin bonus even without any net rotation.

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:

tgggg
ggggttgggg
gggtgggg
gggg
ggggtgggg
gggtttgggg

This one is not strictly a twist, as the tetromino could have been rotated before being dropped:

gt
ggggggtttg
ggggggggg
gt
ggggggttg
ggggggtggg

Triples may not seem possible, but especially games using SRS will allow them regardless.

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.

The following example works only in SRS:

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
gggggggg
ggggg
ggggssgggg
gggssggggg

SRS only:

ggss
gss
ggggggggg
gggggggg
ggggggggg
gg
g
ggggsggggg
ggggssgggg
gggggsgggg

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

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