Crown TSD

Crown TSD is a T-Spin Double setup. It has the same piece dependencies as Amino TSD Subvariant (early I and J, I and L in the mirrored setup). It is invented by Agent RO in November 2020, which is the first TSD opener he invented.

First Bag

Second Bag and later

General Continuations

• LST Stacking

• TST Tower: This can be used as a starter for Infinite TST. The left side can be stacked in any way, only the right side is fixed (S piece on the very right).

• Perfect Clear after 6 lines after T-Spin Single (16.67% PC rate, 5 solutions)

• Perfect Clear after 6 lines after T-Spin Double: If the O piece come before I and S comes before Z then J, you can use this continuation if the O piece comes within the first 2 pieces of the third bag.

Additionally, these continuations keep the unused piece on hold and use J and L in the third bag.

• 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.

Perfect Clear after 8 lines

• L → Z (J on hold, 99.09% PC rate, 42 minimal solutions): It is stacked the same way as the 6-high Perfect Clear continuation in Amino TSD Subvariant, except that the I piece does not touch the bottom of the playfield. This is the best way of getting a Perfect Clear after 8 total lines. This is also one of the best situations if you choose to make a T-Spin Double instead.

• S → J → O (99.01% PC rate, 41 minimal solutions): With SRS, you can kick the Z and L pieces. The first solution can result in a Tetris Perfect Clear.

If the Z, S and J pieces are placed, you can kick the L piece like so.

• J → Z and L → S (83.33% PC rate, 2 minimal solutions): The first solution can result in a Tetris Perfect Clear.
