How to play Stack
Stack is a one-tap tower builder. A block slides back and forth above the tower – drop it at the right moment.
Controls
- Phone: tap anywhere.
- Computer: click, or press the space bar.
Rules
- Whatever hangs over the block below is cut off, so the next block is narrower.
- Drop exactly on top for a perfect drop. Three perfect drops in a row make the block wider again.
- If the block misses the tower completely, the run ends.
Points
Every block on the tower is one point. The block speeds up as the tower grows, and the starting speed adapts to how well you play.
Pause and ads
Use the pause button at the top during a run. After a good run you can watch an optional video to continue once. Sometimes a short ad appears between runs, never during play.
