Special Triple Triple

The Triple Triple setup was designed by player Chopin of Tetris. Yielding the same output as B2B T-Spin Triple builds, this setup is lower and is less easily topped out. This is one of the more advanced setups out there. Fast execution and good piece perception as well as a good knowledge of spins is essential for success. This is a rather new build so improvements will be seen. Note that the shape is very similar to Triple Double builds, just the hole in the floor is shifted.

General Formation and Execution
The general shape is the same as a Triple Double Attack setup, except the hole on the very bottom is shifted by 2 colunms to the right (left for the mirrored setup). After the first T-Spin Triple, use an S or Z piece to make the second notch.

Chopin's Special TT
This is an opener invented by Chopin and Kennyboy2. The key of this setup is understanding piece order and looking ahead. The second bag is stacked in any way but if one can stack like the one in the second and third diagrams, it is ideal. However, if the Z piece comes early, it is best if it is placed on the first bag's Z piece, but you will not be able to make a T-Spin Triple in the third bag.

There is a 80% chance to stack the opener below, or if the mirrored setup is also considered, then it is 83.33%.

Note Stacking
Note Stacking is a setup invented by Yuu. From the second bag onwards, it will be stacked freely. An STSD may be stacked in the fourth bag, if a J piece is slid under the overhang made in the third bag.

There is a 91.43% chance to stack the first bag like the opener below, or if the mirrored setup is also considered, then it is 99.05%.

There are 2 ways one can stack the second bag in such a way that it may lead to a Perfect Clear after 6 lines (16.67% at most).

Note Stacking 2
Note Stacking 2 is the succcessor to Note Stacking and the inventor is Yuu. In the second bag, one must pay attention to the order in which the O and J pieces show up. In the third bag, the Z piece is placed next to the overhang of the first T-Spin Triple to make the next T-Spin Triple.

There are two ways the first bag can be stacked to form the same shape. If the mirrored setups are also considered, this opener can always be stacked, or 90% if only the regular setups.

Alternatively, if the I and Z pieces come before O then J in the second bag, there is a 97.26% chance to achieve a Perfect Clear in the third bag.

Elephant TT
Elephant TT is a Triple Triple setup invented by Agent 1568AH. Despite it being a Triple Triple setup, one may not necessarily create a T-Spin Triple in the third bag, depending on how the second bag is stacked.

There are two ways the first bag can be stacked to form the same shape. If the mirrored setups are also considered, there is an 98.89% chance this opener can be stacked, or 90.16% if only the regular setups.

If the O and I pieces come before S then L in the second bag, there is a 97.26% chance to achieve a Perfect Clear in the third bag.
