DC-Spin

DC-Spin/Double C-Spin is a setup that starts with a T-Spin Triple which was then followed by another T-Spin Triple with a broad amount of covered variations. This setup was created by a Hard Drop member named Aitch. It has a similiar pattern as a C-Spin but the first T-Spin Triple is placed a row higher. This setup uses up to 4 bags. The first and the second bags are always possible and the third and fourth bags has a very high chance.

''"I know you said you were not into long openers, and I can respect that. However, the DC-Spin seems to have a consistency most other long openers don't have, and being slow at picking a variation mid setup can be solved by lots of practice." - Aitch''

First Bag
By using either the normal or mirrored version, placing the first bag for this setup is always possible.

Second Bag
One could stack their second bag in a way that looks like this.

Only O should come before Z. If both Z and T come before O in the second bag, the stack above would not be possible. In that case, choose either of these placements below.

Choose carefully on which side one should put their O on, since the first piece of the third bag would fill the hole in order to achieve a T-Spin Triple. The L Tetrimino placement needs another piece to be placed on it in order for the kick to work.

In some occasions, a T might come first in the third bag. In that case, doing a T-Spin Double then filling the hole with the next piece is more recommended instead of placing the second T to cover the hole. That way, there would be 2 garbage lines less but a T would not be wasted.

If an O is the first piece from the third bag, it is best to place it on top of the previous O and then use the next piece to fill the hole. But if the hole-filling block after O is an I, one could place the O on either side of the stack.

In a very slight chance where O is forced to be placed on either side of the hole because of a limited amount of visible NEXT pieces, just place the O and hope that the place picked is correct.

Third Bag
The third bag has many variations depending on the pattern chosen on the second bag and the piece order on this bag.

Pattern 1
The pattern above is the most common second bag pattern.


 * If S in an example below is placed on the right side, it has to be placed after executing the T-Spin Triple and it indicates an Imperial Cross continuation in the 4th bag.
 * If O in an example below is placed on the right side, it has to be placed after executing the T-Spin Triple and it indicates a T-Spin Triple continuation in the 4th bag.

There is also a continuation which could be used if S comes very late in the third bag. The I, O, L and J can be stacked in one of eight ways.

There is also an Imperial Cross option too. There are more ways of doing this other than the ones shown below.


 * The 4th and 6th diagrams' overhang indicates a DT Cannon continuation in the 4th bag.

There is a TSD C-Spin option as well. This is especially possible if T comes early in the third bag. The T has to be spun before any blocks can be placed above it. There are more ways of doing this than shown below.

Pattern 2
The pattern above is when O was placed on the left side in the second bag.

There are many options especially if one opts for an Imperial Cross or a C-Spin.

T-Spin Triple

Imperial Cross

TSD C-Spin

Pattern 3
The pattern above is when O was placed on the right side on the second bag.

There are many options especially if one opts for an Imperial Cross or a C-Spin.

T-Spin Triple

Imperial Cross

TSD C-Spin

Fourth Bag
This bag does not actually have continuations and players can do anything they want from here. There are some suggestions worth trying.


 * The T-Spin Double continuation after the most common form.


 * If I from the third bag is placed on the left side instead, T-Spin Triple continuation after the most common form is very likely.

If the Imperial Cross continuation was used on the third bag, making a DT Cannon in the 4th bag is recommended. It is not hard to do impromptu and one could also improvise on it.

For TSD C-Spin, Z must come before both T or I.
