Tower Stack — a free online arcade game on TotType
Stack blocks perfectly and build the tallest tower you can in Tower Stack, a free arcade game that's all about timing and precision. Tap to drop each sliding block onto your growing tower — land it dead-center for a perfect stack that keeps its full width, or any overhang gets sliced clean off and tumbles away. Chain perfect drops to unlock a power-up that grows your blocks back wider, but watch out: the blocks move faster and faster the higher you climb, and one missed drop ends the game.

How to play Tower Stack
Tap (or press Space) to DROP the sliding block onto the stack. Land it dead-center for a perfect stack + combo; any overhang is sliced off and the block shrinks. Blocks speed up as you climb — miss completely and it's over.
Tips & tricks
- Land blocks dead-center to keep their full width; every third perfect drop in a row grows the block back a little wider.
- Use the dashed guide line — it marks the middle of the sliding block, so line it up with the middle of the block below.
- Pay attention to your tower getting thinner with each overhang slice: if your blocks shrink too much, you won't be able to land another one, so chase perfects early before the speed makes timing impossible.
Frequently asked questions
How do you play Tower Stack?
Tap the screen (or press Space) to drop the sliding block onto the tower below. The block speeds up as you climb, so timing is everything. Land it perfectly in the center to keep your full width and build a combo.
What happens if you overhang in Tower Stack?
Any part of the block that sticks out past the block below gets sliced off and falls away, and your block shrinks to just the overlap. The sliced-off pieces tumble down the screen; if your tower gets too thin, you can't place another block and the game ends.
How do you score and get power-ups in Tower Stack?
You earn 1 point for each block you successfully stack. Every third perfect drop in a row grows your block a little wider (never past its starting width), giving you more room to land the next one — but any drop that isn't perfect resets the chain.
