Rabbit Stacking

Rabbit Stacking  is a Triple Double Opener. It is created by Agent RO in March 2020. This Opener makes a T-Spin Triple in the second bag and usually a Perfect Clear in the third.

First Bag Setup
You can use this Opener if you have an O and J start. You simply need the O piece before I and L. Although you have other possibilities if you have placed the O on the very left, such as Mountainous Stacking.

Second and Third Bags
You can always place the I, L, S and O pieces in these four ways, all resulting in a Perfect Clear chance. The first way is the most preferable.


 * S → O and L → I (94.25% PC rate, 20 solutions): The first solution may result in a T-Spin Single and Tetris before the Perfect Clear.


 * O → S and L → I (79.13% PC rate, 12 solutions)


 * S → O and I → L (73.77% PC rate, 10 solutions)


 * O → S and I → L (58.37% PC rate, 6 solutions)

Third Bag (PC forwent)
If you choose to forgo the Perfect Clear, especially the first two continuations, you can stack an Imperial Cross, which in turn, leads to a 53.81% PC chance.

Otherwise, you can use LST Stacking.

For the third way of stacking the second bag, your best bet is to make a Tetris iff you get an early J piece.

The first two ways shown can be continued in a variety of ways.

There are not any good continuations for the fourth second bag contunation.
