From Hard Drop - Tetris Wiki
Games that use SRS have a peculiar wall kick that allows the T tetromino to be twisted past other blocks in the playfield, resulting in a triple.
General Tips
- The T tetromino can only fit under the overhang either from sliding or from utilizing the T-Spin Single twist. To use the T-Spin Single twist, make sure the wall opposite the overhang is at least two rows high.

- If a T-Spin Triple is built on top of an empty garbage column, the column will be open after the setup is performed if it lies under the notch or the filled column beside the notch. This can also apply to other columns if their heights are lower than that of the empty cell under the overhang.
- The overhang left over by a T-Spin Triple can be cleared with a twist, namely a T-Spin Single. Slides and line clears also work. The T-Spin Single method is best used if one has a T tetromino ready or coming soon. Delaying the removal of the overhang can cause overstacking which may leave them with an awkward stack, and is time taken away from removing garbage underneath the setup. Also see how to remove the overhang with a tetris.

- Try to build the notch above an empty column or cell to set up a T-Spin Double in advance. This combination is referred to as a Triple Double.
- One can bailout of the setup with a T-Spin Double to avoid stacking high over an empty column.

Setups involving T-Spin Triples
The following sections lists techniques/methods that result in at least 2 T-Spin line clears whereas at least one T-Spin Triple is made and the back-to-back chain is never broken. There are further setups involving T-Spin Triples, for example Fiddlesworth, Single Triple (ST2), Special Triple Triple (TT1), Kaslideoscope, Super Spiral, May (latter two break the back-to-back chain).
Back-to-Back T-Spin Triple is a technique where 2 T-Spin Triples are stacked above each other. It is frequently used in mid-game but is barely ever seen as an opener (O piece in corner, clear bottom row with a T-Spin Single or T-Spin Mini).
Triple Double Attack (C-Spin) is a technique that results in a T-Spin Triple followed by a T-Spin Double. It is a popular opener for SZ starts. Experienced players also use this technique in mid-game.
DT Cannon is a technique that results in a T-Spin Double followed by a T-Spin Triple . It is a popular opener for almost every bag (especially useful when the first T piece comes very early). Experienced players also use this technique in mid-game.
BT Cannon is a technique that results in a T-Spin Double followed by a T-Spin Triple. It gained some traction as part of a technique that has a high chance to result in a Perfect Clear after 14 cleared lines (BT Cannon -> C-Spin -> 4-line PC). It also works for SZ starts but is barely used in mid-game.
DT Cannon 2 is yet another technique that results in a T-Spin Double followed by a T-Spin Triple. This technique is only seen once in a blue moon.
Mini Triple (MT1) is a technique that results in a T-Spin Mini followed by a T-Spin Triple. It is not seen often but it can be stacked multiple times above each other, see T-Spin Snaking. Also note that Trinity can be turned into Mini Triple (MT1) followed by a T-Spin Double instead of 3 T-Spin Doubles.
Magic Key (MK) is a technique that results in a T-Spin Double followed by a T-Spin Triple. It can be used in mid-game but is barely ever seen.
King Crimson is a technique that results in a T-Spin Triple followed by a STSD (2 T-Spin Doubles). It is sometimes seen in mid-game or as a follow-up for the TKI 3 Opening (TSD -> King Crimson). It is pretty risky because it requires to stack relatively high.
Albatross is a single-bag T-Spin Double opener which is usually continued with a T-Spin Triple. It works when not more than one of S, Z, T come before O piece in first bag. It is a popular opener because usually the T-Spin Triple can be completed in the second bag.
Petrel is yet another single-bag T-Spin Double opener which can be continued with a T-Spin Triple. It works more seldom than the Albatross opener and the T-Spin Triple cannot be completed in 2 bags, so this opener is as good as never seen.
SZ Double Triple Setups is an opener which results in a T-Spin Double, followed by a T-Spin Triple. It works for SZ starts but is barely ever used. See this DT Cannon section for similar setups.
Mr. T-Spin's STD is an opener which results in a T-Spin Single, followed by a T-Spin Triple and a T-Spin Double. It requires that the O piece and either S or Z appear relatively early in first bag. It is a relatively popular opener because the T-Spin Triple can always be completed at the end of the second bag. Thereby, the resulting stack always looks the same - O, S, Z will form the same shape in second bag.
Pokemino's STD is yet another opener which results in a T-Spin Single, followed by a T-Spin Triple and a T-Spin Double. It works for almost every first bag (not more than one of S, Z, T must appear before either L or J) but it is not guaranteed to get the T-Spin Triple at the end of the second bag (in contrast to Mr. T-Spin's STD). Thus the opener is not that popular. However, the T-Spin Triple can be often split into a T-Spin Double and a T-Spin Single (which means 4 T-Spins clearing only 6 lines in 4 bags) which can be advantageous in certain modes.
Hachispin is an opener which results in a T-Spin Single, followed by a T-Spin Triple and usually a T-Spin Double. The O piece must appear relatively early in first bag. It is a relatively popular opener because there is a chance to get a Perfect Clear after 8 cleared lines (instead of the T-Spin Double).
pwn_by_numbers' Hachispin variation is an opener which results in a T-Spin Single, followed by a T-Spin Triple and usually another T-Spin Triple. Either L or J must appear relatively early in first bag. Certain bag orders can cause complications in second bag, thus this opener is barely ever seen. However, there is a big chance to get a Perfect Clear after 8 lines, if S piece comes first in second bag.
