Double Triple C-Spin

This sub-article for DT Cannon is Under Construction.

Depending on how you stack your second bag, you can stack a C-Spin.

Second Bag 2B
If the O and I pieces come before S.

Stack 3A
The third bag is traditionally stacked this way. If the Z piece comes before S, then I and also the T-Spin Triple before J, then the L piece, you can stack the traditional way. If you must place the J piece early in the third bag, choose one of the three stacks below, as long as the L piece comes late.


 * Setup A (36.11% setup rate, 100% PC rate, 36 minimal solutions): This is the most ideal way to stack the fourth bag in a way that can always result in a Perfect Clear in the fifth bag.


 * Setup B (85.83% setup rate, 99.72% PC rate, 23 minimal solutions): The fourth bag is traditionally stacked this way. This one is relatively easy to assemble because of the circulation of the O, J, I, S and L pieces that make the same shape.


 * Setup C (26.11% setup rate, 99.64% PC rate, 24 minimal solutions)


 * Setup D (53.33% setup rate, 99.01% PC rate, 23 minimal solutions)


 * Setup E (64.72% setup rate, 98.57% PC rate, 6 minimal solutions)


 * Setup F (41.67% setup rate, 96.23% PC rate, 8 minimal solutions)


 * Setup G (21.11% setup rate, 96.11% PC rate, 19 minimal solutions)


 * Setup H (59.17% setup rate, 95.28% PC rate, minimal solutions)

There also exists a setup where if the J piece was kept on hold, you can always get a Perfect Clear. If you must place the J piece, use setup D or E, or alternatively, on the overhang.

Setup 3B

 * Setup A (100% PC rate, 36 minimal solutions): This makes the same shape as setup A of setup 3A.


 * Setup B (96.23% PC rate, 8 minimal solutions): If the S piece comes before L, but the I piece comes after the O piece, you can use this setup (technically S → L).


 * Setup C (67.78% PC rate, 5 minimal solutions): It requires the L piece to come before O and then S and I.


 * Setup D: If any of the setups above are not feasible, one can always stack the compromise (this setup). There are a plenty of ways you can place the pieces of the fifth bag; an example is shown below.

Setup 3C
This is similar to setup 3A, except the J piece was placed after the O piece was placed. Hence, stacking the fourth bag will be easier.


 * Setup A (99.72% PC rate, 23 minimal solutions): The most ideal setup only requires the S piece to come before the L piece.


 * Setup B (91.79% PC rate, 6 minimal solutions): The compromise setup can always be stacked, and also have a chance for a Perfect Clear after 14 lines.

Setup 3D
This is currently the only setup where not all bags will cover both setups.


 * Setup A (99.64% PC rate, 24 minimal solutions)


 * Setup B (68.93% PC rate, 7 minimal solutions)
