Double Triple Cannon Setups

Double Triple Cannon, sometimes referred to as DT Cannon or DT, is a T-Spin combo designed by player TKI. The setup is essentially a T-Spin Double followed by a T-Spin Triple. A player utilizes the T-Spin Triple wallkick in SRS to make a T-Spin Double that leads into a T-Spin Triple. In Tetris variants without instant lockdown it is best to hold the soft drop button until the T-Spin Double has been completed. This makes it instantly drop "through the gap" so the T tetromino doesn't rotate early and end up in the wrong spot.

Empty Field Setups
Because so many DT Cannon setups exist, the player can choose a setup that fits the order of their opening bag of pieces. It is usually possible to hold a T through the second bag and into the third, allowing the player to make both T-spins in quick succession.

DT-Cannon with no T Pieces

In this setup, the player tries to use no T pieces to set up their DT-Cannon. It is only possible to clear this setup within 14 pieces if the second T is at the end of the second bag, but, if successful, this is the fastest DT-Cannon setup. Otherwise, the second T will be used for the upstack, reducing this setup's efficiency to the same as the rest listed here.
