| − | Some games give scoring rewards for twisting a tetromino into a tight space. When this is done with a T tetromino, it is called a '''T-spin'''. |
||
| − | |||
| − | 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 [[The_New_Tetris#Twist_reward|a reward]] if rows are completed in this way. Example: |
||
| − | |||
| − | {| |
||
| − | |{{pfstart}}{{pfrow| | | | | | |g|g| | }} |
||
| − | {{pfrow|g|g|g|g| | | |g|g|g}} |
||
| − | {{pfrow|g|g|g|g| | |g|g|g|g}} |
||
| − | {{pfend}} |
||
| − | Immobile T-slot |
||
| − | |{{pfstart}}{{pfrow| | | | | |t|g|g| | }} |
||
| − | {{pfrow|g|g|g|g|t|t| |g|g|g}} |
||
| − | {{pfrow|g|g|g|g| |t|g|g|g|g}} |
||
| − | {{pfend}} |
||
| − | Entry |
||
| − | |{{pfstart}}{{pfrow| | | | | | |g|g| | }}{{pfrow|g|g|g|g|t|t|t|g|g|g}} |
||
| − | {{pfrow|g|g|g|g| |t|g|g|g|g}} |
||
| − | {{pfend}} |
||
| − | Rotated to a position of immobility, and a row will clear |
||
| − | |} |
||
| − | |||
| − | *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> |
||
| − | |||
| − | *#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. Example: |
||
| − | |||
| − | {| |
||
| − | |{{pfstart}}{{pfrow| | | | | | |g|g| | }}{{pfrow|g|g|g|g| | | |g|g|g}} |
||
| − | {{pfrow|g|g|g|g|g| |g|g|g|g}} |
||
| − | {{pfend}} |
||
| − | 3-corner T-slot |
||
| − | |{{pfstart}}{{pfrow| | | | | |t|g|g| | }}{{pfrow|g|g|g|g|t|C| |g|g|g}} |
||
| − | {{pfrow|g|g|g|g|g|t|g|g|g|g}} |

||
| − | |{{pfstart}}{{pfrow| | | | | | |B|g| | }}{{pfrow|g|g|g|g|t|C|t|g|g|g}} |
||
| − | {{pfrow|g|g|g|g|B|t|B|g|g|g}} |
||
| − | {{pfend}} |
||
| − | Rotated and 3 corners are occupied in the 3x3 box which contains the T |
||
| − | |} |
||
| − | |||
| − | [[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". 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]]'', ''[[Tetris Evolution]]'', and most other official guideline games released after 2006: The final rotation must not involve a wall kick, that is, it recognizes only the "well known twist" below. |
||
| − | *[[Tetris Zone]] recognises T-spins that involve a wallkick, but will not recognise any T-spin that results in a triple. |
||
| − | |||
| − | == Rewards == |
||
| − | Rewards for T-spins first appeared in ''[[The New Tetris]]''. The game added a reward for T-spins (and for twists involving other pieces), which would trigger an "avalanche." [[Henk Rogers]] implied in his planetgamecube.com interview that it was the mobile game ''[[Tetris Battle]]'' that inspired the T-Spin's current dominating points and garbage rewards, although T-Spins in a nerfed form found their way into prior guideline games such as ''[[Tetris Worlds]]''. As of 2008, the [[Tetris Guideline]] seems to favor the 3-corner T no kick rulings. |

| − | == T-Spin Mini == |
||
| − | Some games (before 2006) reward T-Spin Minis. There are three cases: |
||
| − | # T-Spin Single/Double with wallkick |
||
| − | # Singles/Doubles with the TST twist |
||
| − | # T-Spin with hole behind T |
||
| − | |||
| − | Tetris DS treats case 1 and 2 as a T-Spin Mini. |
||
| − | |||
| − | Tetris Online (Japan) treats the T-Spin as a Mini if there is a hole behind the T. Therefore it treats case 1, 3, and sometimes 2 as mini. |
||
| − | |||
| − | Tetris Friends treats the T-Spin as a Mini if only one cell next to the pointing side is occupied, and upgrades it to standard if it is the TST twist. |
