When you do a perfect-clear loop that takes 8 lines to complete, such as First-Second perfect clear, SingleYou or Mountainous Stacking, you will be left with an empty board and an extra piece. A DPC setup will use the extra piece and 2 bags to create a T-Spin and a perfect clear, bringing you back to the beginning with no extra pieces, to continue the loop.

Note: T-Spin percentages do not include TSMS.

Note: All setups on this page are 100%. However, you may need 180 spins for some solves.

Generally, one should prioritize saving O and S/Z, although I is also viable. Try to avoid saving J/L and T whenever possible, as they yield the lowest scoring patterns.

Extra setups can be found at Extra DPC Setups.

O piece

O -> L/J (Kuruma DPC)

L/J -> O (TSD DPC)

S/Z piece

O -> S/Z (Kuruma DPC)

S/Z -> O (Lime DPC)

Lime DPC is notoriously hard to solve and scores very little on average; avoid it when possible.

I piece

O -> I (Fake Butter DPC)

This setup will have to be mirrored depending on whether J or L comes first.

JL -> O (Pelican DPC)

This setup will have to be mirrored depending on whether S or Z comes first.

I -> O -> L (Bad TKI DPC)

This pattern, when mirrored, will cover the bags not covered by the previous 2 setups. However, you should avoid it when possible due to mediocre scoring.

J/L piece

Note: These setups are not 100% consistent without 180 spins. If you have the L piece, the piece requirement is flipped.

Z -> S (TSM J SPC)

Different builds depending on whether the O or the S comes first. A third of the time, you will be able to make a TSS into Tetris.

T piece (OSZ Ball DPC)

There is only 1 pattern needed. It does not require mirror.
