The Hummingbird is a quick and efficient T-Spin Single opening setup for early S/Z bags. It only requires 5 tetrominos to execute, and can easily be followed up with a STSD.

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 after the first J/L in its respective position regardless of whether it comes before or after the T-spin.

In cases where both J and L must be placed before the T-spin can be executed, a similar setup can be used. Note that in the following example, the O block is on the other 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 a STSD.

Following an early J and L

After the usual T-Spin Single, this setup can result in an imperial cross, given the setups below. 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.

Perfect Clears following the first setup (to perform any of these, the knowledge of S and Z spins is required):
