==Rewards for twists==
==Rewards for twists==
Some games give scoring rewards for twisting a tetromino into a tight space. Two basic algorithms, with slight variations, have been used in newer games to detect and reward in-place spins:
Some games give scoring rewards for twisting a tetromino into a tight space. Two basic algorithms, with slight variations, have been used in newer games to detect and reward in-place spins:
*Immobile, used 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.
*Immobile, used in ''[[The New Tetris]]'': A twist is recognised if a tetromino locks in a position where it cannot move left, right, or up. There is only [[The_New_Tetris#Twist_reward|a reward]] if rows are completed in this way.
*3-corner T, used in ''[[Tetris DS]]'' and other [[SRS]] based games: A T-spin bonus is awarded if all of the following are true:<sup>[http://www.tetrisconcept.com/forum/viewtopic.php?t=78]</sup>
*3-corner T, used in [[Tetris Guideline]]-based games: A [[T-Spin]] bonus is awarded if all of the following are true:<sup>[https://tetrisconcept.net/threads/i-cant-get-t-spins-to-work-_.415/#post-17830]</sup>
*#Tetromino being locked is T.
*#Tetromino being locked is T.
*#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&ndash;A or A&ndash;B) will trigger the T-spin bonus even without any net rotation.

[[Guideline compliant game differences|Different games]] add further restrictions:
*3-corner T no wall, used in ''[[Tetris Worlds]]'': The walls and floor surrounding the playfield are not considered "occupied".
*3-corner T no wall, used in ''[[Tetris Worlds]]'': The walls and floor surrounding the playfield are not considered "occupied". This means that if a wall kick places the T tetromino with its flat side against the wall or floor, the T-spin will not be recognized. (Kicks that place the flat side against blocks in the playfield still work.)
*3-corner T no kick, used in ''[[Tetris: New Century]]'' and ''[[iPod Tetris]]'': The final rotation must not involve a wall kick, that is, it recognizes only the "well known twist" below.
*3-corner T no kick, used in ''[[Tetris: New Century]]'', ''[[iPod Tetris]]'', and ''[[Tetris Evolution]]'': The final rotation must not involve a wall kick, that is, it recognizes only the "well known twist" below.

[[Tetris Stardust]] awards a Spin Rank when the player performs twists with any tetromino, if the twist moves it below its previous lowest position. The score associated with Spin Rank is separate from action scores such as line clears.


In some of these diagrams, especially those involving ''S'' and ''Z'' [[tetromino]]es, the "center" corresponding to the center of rotation in [[SRS]] is marked with a circle ([[Image:CTet.png|C]]).

In SRS games that reward kick T-Spins like ''[[Tetris DS]]'' and ''[[Tetris Zone]]'', making use of a wall kick saves a bit of soft-dropping time. This will not count in several Guideline games like ''[[Tetris Evolution]]'' or ''[[Tetris Splash]]''; later games including ''[[Tetris Effect]]'' will detect this kick as a T-Spin.

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.

This example from SRS is not a T-spin under the old rule, as the tetromino could have been rotated before being dropped, but SRS games from ''Tetris Worlds'' through ''Tetris DS'' count it anyway:
The above move must be done differently in ''[[The New Tetris]]'', but also works and in games using ARS. As this does not involve a wallkick in TGM, it also works in Sega rotation:

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.
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. Several later guideline games don't recognise this, either by not counting triples made with this twist as a T-spin (''[[Tetris Zone]]''), or by not recognising this twist as a T-spin at all (''[[Tetris Evolution]]''). However, beginning with ''[[Tetris Friends]]'', T-Spin Triples performed with this setup are always rewarded.

==<span id="O">Twists with ''O''</span>==
Most Tetris games do not move the O tetromino when rotated or allow it to kick. However, [[Tetris 64]] and [[Tetris Stardust]] use custom rotation systems allowing O twists.
 
In Tetris 64, "Rotate Center" and "Offset Turn" must be enabled.
 
For all O twists in Stardust, always rotate in the direction of horizontal movement.

For the mirrored setup, rotate right in T64. This is because rotating 0->R in T64 naturally moves the O tetromino down, then allows it to kick in either direction.

Twists, called "spin moves" in The New Tetris's manual, 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.

Rewards for twists

Some games give scoring rewards for twisting a tetromino into a tight space. Two basic algorithms, with slight variations, have been used in newer games to detect and reward in-place spins:

  • Immobile, used in The New Tetris: A twist is recognised if a tetromino locks in a position where it cannot move left, right, or up. There is only a reward if rows are completed in this way.
  • 3-corner T, used in Tetris Guideline-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.

Different games add further restrictions:

  • 3-corner T no wall, used in Tetris Worlds: The walls and floor surrounding the playfield are not considered "occupied". This means that if a wall kick places the T tetromino with its flat side against the wall or floor, the T-spin will not be recognized. (Kicks that place the flat side against blocks in the playfield still work.)
  • 3-corner T no kick, used in Tetris: New Century, iPod Tetris, and Tetris Evolution: The final rotation must not involve a wall kick, that is, it recognizes only the "well known twist" below.

(The names for the algorithms are unofficial, taken from the fan game Lockjaw.)

Tetris Stardust awards a Spin Rank when the player performs twists with any tetromino, if the twist moves it below its previous lowest position. The score associated with Spin Rank is separate from action scores such as line clears.

In some of these diagrams, especially those involving S and Z tetrominoes, the "center" corresponding to the center of rotation in SRS is marked with a circle (C).

Twists with T (or T-Spin)

Main article: T-Spin

A well-known twist involves the tetromino T. In fact, these are the only twists that games that use "3-corner T no kick" reward.

     TGG
GGGGTC GGG
GGGGGTGGGG

      GG

GGGGGTGGGG

Soft drop

      GG
    TCTGGG
GGGGGTGGGG

Rotate once

     TGG
     CTGGG
GGGGGTGGGG

Or twice

In SRS games that reward kick T-Spins like Tetris DS and Tetris Zone, making use of a wall kick saves a bit of soft-dropping time. This will not count in several Guideline games like Tetris Evolution or Tetris Splash; later games including Tetris Effect will detect this kick as a T-Spin.

Rotate right

The following works in Tetris DX, ARS, and SRS, but it is not scored as a T-spin in Tetris Worlds if performed on the floor of the playfield.

     TGGGG
GGGGTTGGGG
GGG  TGGGG

Soft drop

      GGGG
GGGGT GGGG
GGGTTTGGGG

Rotate right

The above move must be done differently in The New Tetris, but also works and in games using ARS. As this does not involve a wallkick in TGM, it also works in Sega rotation:

    O GGGG
GGGGOOGGGG
GGG O GGGG

Firm drop

      GGGG
GGGGO GGGG
GGGOOOGGGG

Rotate left

This example from SRS is not a T-spin under the old rule, as the tetromino could have been rotated before being dropped, but SRS games from Tetris Worlds through Tetris Online (Japan) count it anyway:

     G T
GGGGGGTTTG
GGGGGG GGG
     GT
GGGGGGTT G
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:

 T       G
TCTGGGGGGG
 GGGGGGGGG
T        G
CT GGGGGGG
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. Several later guideline games don't recognise this, either by not counting triples made with this twist as a T-spin (Tetris Zone), or by not recognising this twist as a T-spin at all (Tetris Evolution). However, beginning with Tetris Friends, T-Spin Triples performed with this setup are always rewarded.

This one works in Atari rotation:

   GG
   GSSS
   G S
GGGG GGGGG
   GG
   GS
   GSS

And this works in both SRS and Atari rotation (assuming there is a rotate right button):

Twists with I

Works in TGM and SRS:

GGGGGGGGI
GGGGGG  I
GGGGGGGGI
GGGGGGGGI
GGGGGGGG
GGGGGGIIII
GGGGGGGG

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

GGG I  GGG
GGGGIGGGGG
GGGGIGGGGG

Rotate left

GGGG GGGGG
GGGIIIIGGG
GGGG GGGGG
GGGG GGGGG

Rotate right

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
GGGGI   GG
   G G
GGGG GGGGG
GGGGIIIIGG

This one works in SRS and Atari rotation:

GGG
GGIIII
GG GGGGGGG
GG GGGGGGG
GG GGGGGGG
GGG
GGI
GGIGGGGGGG
GGIGGGGGGG
GGIGGGGGGG

SRS has a slight asymmetry with how end-block rotation is handled. See I-spins in SRS.

This one is silly but should work (with minor variations) in most systems, even if it is not rewarded:

GGG
GG
GIIII
GG GGGGGGG
GG GGGGGGG
GGG
GGI
G I
GGIGGGGGGG
GGIGGGGGGG

The minor variation required for TGM and Sega rotation systems is to do a mirror-image version. This also works in SRS, as well as other systems where I rounds to the right and has no wallkick:

       GGG
        GG
     ZZZZG
GGGGGGG GG
GGGGGGG GG
       GGG
       ZGG
       Z G
GGGGGGGZGG
GGGGGGGZGG

In games that use Atari rotation, a similar maneuver can produce a triple:

GGG
GZZZZ
GG GGGGGGG
GG GGGGGGG

GGG
G Z
GGZGGGGGGG
GGZGGGGGGG
GGZGGGGGGG

Twists with O

Most Tetris games do not move the O tetromino when rotated or allow it to kick. However, Tetris 64 and Tetris Stardust use custom rotation systems allowing O twists.

In Tetris 64, "Rotate Center" and "Offset Turn" must be enabled.

For all O twists in Stardust, always rotate in the direction of horizontal movement.

T64 and Stardust:

GGGOOGGGGG
GGGOO GGGG
GGGG  GGGG
GGG  GGGGG
GGG OOGGGG
GGGGOOGGGG

For the mirrored setup, rotate right in T64. This is because rotating 0->R in T64 naturally moves the O tetromino down, then allows it to kick in either direction.

T64 and Stardust:

  • In T64, double-tap any rotation button to perform. Requires "Double Turn" to be enabled.

Twist Option

Sometimes there is more than one way to twist a piece into a hole. Think about which twist is best for the situation. Which cells should be filled, and which should be left behind?
