How to play
- Drop the block. A block slides side to side - tap, click or press Space to drop it onto the tower.
- Mind the overhang. Any part hanging over the edge is sliced off, so each miss makes the next block thinner. A perfect drop keeps the full width.
- Build as high as you can. Your score is the number of blocks stacked - miss the tower entirely and the run ends.
About Stack
Stack is the hypnotic tower-building game of timing and nerve. A block slides back and forth above the tower - tap, click or press Space to drop it. Whatever hangs over the edge is sliced clean off and falls away, so every imperfect drop leaves the next block a little narrower. Nail a perfect, edge-to-edge drop and you keep the full width; miss the tower completely and it is game over. The camera rises with every block, and the blocks slide faster the higher you build. Your score is the number of blocks you stack, and your best is saved locally. No signup.
Frequently asked questions
A block slides back and forth above the tower. Tap, click or press Space to drop it. Try to line it up over the block below - the part that overhangs is cut off and the rest is added to the tower.
Your score is the number of blocks you successfully stack. Every block you land adds one, and your tallest tower is saved as your high score.
If you drop a block almost exactly on top of the one below, it snaps into place and keeps its full width instead of being trimmed - perfect drops let you keep a wide, stable tower.
The run ends when a dropped block misses the tower completely with no overlap, so there is nothing left to slice and stack.
Yes. The block slides faster as the tower grows, and higher difficulty starts it moving faster, so each drop demands sharper timing.
