Drop the moving piece into the middle. Clean landings raise combo. Misses tilt the stack and speed up the next round.

Timeline overview

Open the guide, place the first piece, then keep the stack balanced as the speed increases. The run ends when the tower falls or time runs out.

Step 1: setup

Use touch, mouse, or keyboard. The play area is active immediately, and the first piece is already moving so you can begin without extra steps.

Step 2: action

Tap at the right moment. A clean center hit adds score, strengthens combo, and reduces wobble. The accent color marks the active target and the score cue.

Step 3: review

After the run, check your final score and session best. Beating your best score triggers a small cue so you know the stack improved.

Common pitfalls

1
Do not chase the edges; they build tilt faster.
2
Do not spam taps; wait for the clean lane.
3
Reset your rhythm after a miss, then rebuild combo.
