List of twists

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.
Most twists can be done in Tetris Best or Tetris Return. Some can be done through a diagonal slide in Tetris Best 2.

==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 DS and other SRS based games: A T-spin bonus is awarded if all of the following are true:
*#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–A or A–B) will trigger the T-spin bonus even without any net rotation.
*#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.)
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 ().
== Twists by tetrimino ==
===Twists with T (or 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.
Soft drop	
Rotate left
Soft drop	
Rotate once	
Or twice
In SRS games that reward kick T-Spins like Tetris DS and Tetris Zone, these twists count towards the score. This one does not count towards the score in games like Tetris Evolution or Tetris Splash.
Soft drop	
Rotate right
The following works in Tetris DX, TGM rotation, and SRS, but it is not scored as a T-spin in Tetris Worlds if performed on the floor of the playfield.
Soft drop	
Rotate right
The above move must be done differently in The New Tetris, but also works in games using TGM rotation, but not SRS. As this does not involve a wallkick in TGM, it also works in Sega rotation. This diagram will use TNT colors.
Firm drop	
Rotate left
This example from SRS is not a T-spin under the immobile rule, as the tetromino could have been rotated before being dropped, but SRS games from Tetris Worlds through Tetris Online (Japan) count it anyway due to the 3-corner rule:
	
This one is a T-spin in Tetris DS but not Tetris Worlds due to the difference in how the playfield walls are handled:
	
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. 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 twists with kicks as a T-spin at all (Tetris Evolution).
Soft drop and slide	
Rotate left
Tetris Best only:
Soft drop and slide	
Rotate left
This T-spin works in Atari rotation:
	
And this works in both SRS and Atari rotation (assuming there is a rotate right button for Atari):
	
A complicated SRS example:
			
===Twists with I===
Works in TGM and SRS:
	
If changing position to the second row, rotate three times so to twist on lower-middle square.
	
Rotate left	
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:
	
This one works in SRS and Atari rotation:
	
SRS has a slight asymmetry with how end-block rotation is handled, preferring left end block rotations over the right. See I-Spins in SRS. If rotating on the right end block instead of the left, you need an extra block to force a kick down, or the edge of the playfield can be used in place of the extra block.
This one is silly but should work (with minor variations) in most systems, even if it is not rewarded (if the game rewards twists other than T):
	
It can also form a triple or Tetris if the stack is higher, also with minor variations.
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. We will use TGM colors for this diagram.
	
In games that use Atari rotation, a similar maneuver can produce a triple (or Tetris if there is one more row of minos):
	
For Tetris Best, this is the I-Spin Tetris. It works from both directions:
	
SRS variation (also works in Tetris Best and Atari):
	
===Twists with S and Z===
Game Boy, Sega, TDX, TGM, SRS

NES, Sega, TDX, TGM, SRS

SRS and DTET:
Rotate rightand soft drop	
Rotate right again
SRS and DTET:
	
SRS only:
	
	
No overhang method
	
	
Another S-Spin Double in SRS:
	
===Twists with J and L===
Works in virtually all versions, including Tetris (Game Boy):
	
	
Works with TGM and SRS:
	
	
	
	
(For the last one, the block highlighted in red is needed in TGM, but is optional in SRS. The edge of the field may also be used in place of that block.)
Works with TGM and TOD:
	
	
Note: For J in TGM, when there is only one row of minoes to the right of the J, you need an extra mino to force a kick left.
Works with SRS only:
	
	
	
	
	
	
	
	
	
	
Like other spin triples, this works with SRS only: (mirror image for L)
	
Also works with higher overhang:
	
In Tetris Best, it also works without an overhang. It also works with the tetrimino pointing down.
Atari rotation is a special case. It does this:
	
This one is only for Tetris Best 2 (only works for J):
	
=== O-spins (Tetris Best/2) ===
O-spins can be done with a diagonal slide, which was there since the old Tetris Best.
	
Other O-spins can be done in Tetris Best only.
	
==180° Twists (NullpoMino only, any tetrimino)==
For games with 180° rotation buttons other twists are possible. All of them work in NullpoMino. Some don't work in Tetris Best due to having 3-kicks, and Tetris Best only goes to 2.
Tetris Best 2 also has 180 rotation, but only floorkicks. However, some twists can be done with a diagonal slide in Tetris Best (or 2). These twists are marked with an asterisk.

===Teleporting===
With 180° spins it is possible to pass through solid walls. This is called teleporting.
	
	
	
	
	
==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?
	
SRS only
