Hummingbird

Hummingbird (formerly Subscriber Special) is a quick and efficient T-Spin Single opening setup for early S/Z bags. It only requires 5 tetriminos to execute, and can easily be followed up with an STSD. L piece must be placed after completing the second line.



Build Order
In order to build the Hummingbird with an SZ start, it is required to place exactly one J piece or L piece before the T-Spin Single. The I piece can be placed on the first J/L in its respective position regardless of whether it comes before or after the T-Spin.

If both J and L must be placed before the T-Spin can be executed, a similar setup can be used. Note that the O piece is on the left side of the T-Spin, thus it is essential to know the queue before choosing this setup or the Hummingbird proper.

STSD Transition
The following setups cover most circumstances when transitioning to an STSD.

TSD Conversion
The T-Spin Double can be converted to a T-Spin Triple, Imperial Cross, Trinity. 4-Wide is also possible (not shown).

Early J and L
After the T-Spin Single, the setup is usually continued with an Imperial Cross. The first two setups have a decent chance of resulting in a Perfect Clear, but the third setup should only be used for unfair bags, which cannot result in a Perfect Clear.

First setup: 23 solutions



Second setup: 1 solution (Both T-Spin Single and Tetris can happen)
