Block Stack
Drop the blocks and build the tallest tower.
Block Stack is a one-tap timing game. A block slides back and forth above your tower. Tap to drop it. Whatever hangs over the edge falls off, so the next block gets smaller.
Drop a block perfectly on top and it keeps its full size, with a sparkle and a combo bonus. How high can you build before you miss?
How to play
- Press Play and watch the sliding block.
- Tap, click or press Space to drop it on the tower.
- Line it up with the block below to keep it big.
- Keep stacking until a block misses the tower.
