List of twists

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), as opposed to sideways movement, downward movement, or falling due to gravity.
  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.

Other variants exist, especially in games that use some form of wall kick:

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

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.

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

The following example works only in SRS:

Twists with S and Z

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

SRS only:

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):

Works with TGM and SRS:

Works with TGM and TDS only, excluding other SRS games
