ST Stacking

ST stacking is a more-or-less sustainable (under Random Generator) method of stacking tetrominoes to form successive 4-line clears and T-spins. In Tetris DS standard mode, this stacking method achieves near maximum points per line. It's superficially similar to one of the T-spin triple setups but allegedly easier to learn.

First build this

Drop an S

Spin a T

T-spin double

Leaves one row of garbage

Build more layers

Another S and T

T-spin double

Leaves another identical row

After a few rows of garbage have accumulated, use I tetrominoes to break it down:

Look at the mess in aisle 2!	Aisle 2? "I" know what to do	Another S and T	T-spin double
Build more	Drop next I	Tetorisu!	Ahh, that's better.
