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 continute the loop.
Note: All setups on this page are 100%, however, you may need 180 spins for some solves.
O piece
O -> L
Solutions:
This is a solve that can get you a Tetris where others wouldn’t, but is not neccessary.
L -> O
Note: This is the most efficient Extra O DPC.
Solutions:
These are 2 setups that can get you extra T-Spins.
S/Z piece
O -> S/Z
Notably, this shape is the same as the extra O DPC when you have O before L, so it has the same solutions.
Solutions:
This is a solve that can get you a Tetris where others wouldn’t, but is not neccessary.
S/Z -> O
Solutions:
The last solution may sometimes yield a TSS or TSD.
I piece
O -> I
This setup will have to be mirrored depending on whether J or L comes first.
Solutions:
JL -> O
This setup will have to be mirrored depending on whether S or Z comes first.
Solutions:
These are 2 setups that can get you extra T-Spins.
I -> O -> L
This pattern, when mirrored, will cover the bags not covered by the previous 2 setups.
Solutions:
J/L piece
Note: These setups are not 100% consistent without 180 spins.
S -> Z
If you have the L piece, the piece requirement is flipped.
Solutions:
Z -> S
Different builds depending on whether the O or the S comes first. Occasionally, you will only get a T-spin Mini, but the setup makes up for it with it's T-spin chances.
66.67% T-spin single, 33.33% T-spin double, 33.33% T-spin single + Tetris.
Solutions:
T piece
There is only 1 pattern needed, however it will need to be mirrored denpding on whether L or J comes first.
T
Solutions:
These setups are not needed to do DPC, however if you are playing TETR.IO Blitz or Jstris Ultra, you can build these setups for extra T-Spin/Tetris chances.
Two line Perfect Clear
Whenever you have an extra O, there is a 1/7 chance to have a 2-height perfect clear, into TSZ 7th. This is by far the best
scoring setup, and TSZ 7th is easy to learn.
TSZ 7th build:
Solutions:
Butter box
This is an easy setup to learn, and scores a lot under high-gravity pressure in TETR.IO blitz. Good to learn.
Solutions:
This is a solution that can get you an extra T-Spin.
This setup is very easy to learn, and has good Tetris/T-Spin chances. There are 2 different ways to build it.
Solutions:
This is a solution that can get you an extra T-Spin.
Very similar to the normal TKI, however scores a lot more with it's 2 extra T-Spin solves, in exchange for a lower build rate.
Solutions:
These are 3 solutions that can get you an extra T-Spin.
O -> S
This creates the same shape as O DPC when you have L before O
Solutions:
These are 2 setups that can get you extra T-Spins.
This is an interesting setup, as it is the O that is placed last. Very good for scoring.
Solutions:
This is a solve that can get you an extra T-Spin.
Yet another O L -> O congruent
This setup is so efficient, you have 3 ways of building it!
Solutions:
These are 2 setups that can get you extra T-Spins.
There are 3 different ways to build this setup. Very similar to the extra O TKI.
Solutions:
This is a solution that can get you an extra T-Spin.
J/O -> S, L -> I
A decent extra J DPC with good coverage, and is easy to learn. There are 2 ways to build the setup.
Solutions:
Note: The first 2 solutions have 98% coverage.
STSD DPC
Note: This setup is 99.72%
Solutions:
These are some extra solves that can get you into T-Spins.
If you want some extra score, you can build DPC instead of a SPC. Creates the same shape as Extra J S -> Z
