❓ Frequently Asked Questions
How do combos work in Stack Master?
Landing a block perfectly aligned with the one below triggers a combo. Consecutive perfect drops increase your combo multiplier, giving you bonus points and special visual effects.
What happens when I misalign a block?
The overhanging part gets cut off, making the next block smaller. Multiple misalignments shrink the tower quickly, making it harder to land. One perfect drop resets the block to full width.
