About Stack
Tap to drop each moving block onto the stack. Any overhang gets cut off; a perfect landing earns a bonus and restores some width. Study questions appear every few floors. Correct answers earn helpers such as a slower block, automatic alignment, or a shield. Wrong answers make the next drop harder. A complete miss ends the run.
How to Play Stack
One-tap stacking, with bonuses for clean lined-up drops
The view climbs with you, from city lights up into space
Right answers earn helpers: slow-mo, auto-align, or a one-time shield
Blocks land with a squash and a chime that climbs with your streak
