TETRIS GLOSSARY
STSD
Also called Super T-Spin Double · Super TSD
One connected structure that yields two T-spin Doubles. Often recognized through a three-by-three empty region with J/L construction. It is a distinct geometry from Fractal, not a name for any two consecutive TSDs.

The first T completes two rows.
After the first Double, the same structure leaves a second T slot.
The second T completes the next two rows.
Both Doubles are complete. The remaining blocks still need to be managed.
