Advanced Tetris: T-Spins and Combos
Once flat stacking and the well feel natural, two techniques push your score higher: the T-Spin and the combo chain. Both trade a little safety for a lot of points.
What a T-Spin is
A T-Spin is clearing lines by rotating a T-piece into a notch it couldn't slide into — the rotation itself kicks it into place. It scores far more than a normal clear of the same number of lines, and a T-Spin Double is one of the most point-efficient moves in the game.
Building the slot
You need a T-shaped hole with a block overhanging one side, so the piece can only enter by rotation. Leave a three-wide notch with an overhang as you stack, then wait for a T-piece. The hard part is resisting the urge to fill the slot with other pieces.
Combo chains
A combo is clearing a line with consecutive pieces, one after another with no gap. Each link in the chain adds bonus points. To set one up, build a staircase where every new piece completes exactly one row, then feed the staircase piece by piece.
Both techniques raise your stack and your risk. Only reach for them when your board is calm — never while you're digging out of trouble.
Recovering a messy stack
When holes appear, stop chasing Tetrises. Switch to clearing single and double lines to expose the buried hole, accept the lost points, and rebuild a flat surface. A calm recovery beats a greedy collapse every time.
