TETRIS GLOSSARY

A floating TSD made by hanging S or Z across a three-column gap. Because the spin sits above empty space, verify the supporting corners and the board left after clearing.

Air T-spin →
A T-spin setup built above an empty area rather than directly on a solid floor. Plan what the clear exposes underneath; a floating slot is useful only if its entry and follow-up work.
Fractal Cave →
A Fractal-related construction using an STMB Cave above an incomplete TSD. The upper spin must leave the intended lower slot usable after its rows disappear.
