How to play Stack Tower

  1. A block slides back and forth above your tower. Tap when it lines up with the block below.
  2. Any part that hangs over the edge is sliced off and falls away, so the next block gets narrower.
  3. Drop a block almost exactly on top to score a Perfect and keep its full width.
  4. Three Perfect drops in a row make your block grow back wider. Miss the tower completely and it is game over.

Controls

Click, or press Space / Enter, to drop the block.

About Stack Tower

Stack Tower is a simple idea that is hard to put down. One block slides across the screen, you tap to drop it, and whatever overhangs the tower is cut away. Each floor is a little narrower than the last unless you are precise, and the game ends the moment a block misses completely.

What makes it tense is the trade-off between speed and accuracy. The block accelerates as the tower grows, so the same reflex that worked at floor ten is not quite enough at floor thirty. Perfect drops reward careful timing by keeping the block wide, and a streak of them even grows it back.

This browser version uses a colour that shifts with every floor and a camera that follows the top of the tower, so you always see what you are aiming at. Runs are short, restarting is instant, and your best score is saved on your device, which makes it ideal for quick breaks.

Tips and strategies

  • Watch the edges of the tower, not the middle of the moving block.
  • Stay calm when it speeds up — the rhythm stays the same, only faster.
  • Chain Perfect drops early to build a wide base you can afford to waste later.
  • A thin block is not the end: one good streak widens it again.

Stack Tower FAQ

How is the score calculated?

Your score is the number of floors you have stacked. Each successful drop adds one floor.

What counts as a Perfect drop?

Landing within a few pixels of the block below. Perfect drops cut nothing off, and three in a row make the block wider again.

Does the game get faster?

Yes. The block moves a little quicker with every floor until it reaches a top speed, so timing gets harder the higher you go.

Can I play Stack Tower on mobile?

Yes, just tap the screen. It works in any modern browser, with no download or sign-up.
