Stack Tower Game

The objective is simple: drop each moving block onto the tower below and keep it as aligned as possible. A clean overlap keeps your block wide and builds a combo; a sloppy one trims it down; a total miss ends the run. Free, no sign-up, no download — just click, tap, or press Space and see how high you can stack.

One-button controls

Click, tap, or press Space to drop the block — the whole game is understandable in seconds.

Ramping difficulty

The block speeds up and narrows as your tower grows, so every run gets tougher the higher you climb.

Perfect-drop combos

Near-perfect placements keep your full width and stack into a combo streak with bonus points.

Frequently asked questions

How do you play Stack Tower?
A block slides back and forth above your tower. Click, tap, or press Space to drop it onto the block below. Whatever overlaps stays; whatever misses falls away. Line up an almost-perfect drop and your block keeps its full width instead of shrinking, building a combo. Miss completely and the run ends.
What are the controls?
Click or tap anywhere on the board, or press the spacebar, to drop the moving block. The same action starts a fresh run from the title screen and restarts after Game Over. A Pause button and Restart button sit next to the board on any device.
Does the game get harder as I go?
Yes. The moving block speeds up the higher your tower gets, and every imperfect drop trims the block a little narrower — so later placements demand tighter timing on a smaller target.
What's a "perfect" drop?
Lining the moving block up almost exactly with the block below counts as perfect: your width is preserved instead of being cut down, and consecutive perfects build a combo streak with a small score bonus.
Is my high score saved?
Your personal best is stored locally in your own browser, so it's there next time you visit on the same device. It never leaves your machine — there's no account and no server-side leaderboard.
Is it really free, and does it work offline?
It's completely free with no sign-up, no ads to click through, and nothing to install. The whole game runs in your browser on a canvas, so once the page has loaded it keeps working even with a flaky connection.
