Second Bag and later
There are several ways to stack the second bag, though some will result in a shape that can be Perfect Cleared.


 * LST Stacking


 * Perfect Clear continuations: The best one has a 99.01% chance of making a Perfect Clear after 8 total lines (S→J→O). The L and Z can be kicked in. Afterwards, there are more than 30 solutions this shape has. The first solution can result in a Tetris Perfect Clear.

If one gets an early J and L, then the below alternative is possible. There are 4 solutions and the PC chance is 83.33 %. The first solution can result in a Tetris Perfect Clear.


 * Perfect Clear after 12 total lines: There are various ways to achieve this. This example uses an early L and O in the second bag.
