Is Stack free to play?

Yes. Stack runs free in your browser with no installs, downloads, or sign-up, on both desktop and mobile.

How do you win Stack?

There is no win screen — Stack is an endless score chase. The run ends when a block misses the tower entirely, and your tallest tower is saved as your best.

How do perfect drops work?

A near-perfect, flush drop keeps the block's full width, and four perfect drops in a row regrow the block a little, rewarding precision.

Does Stack work on mobile?

Yes. The game is one-tap and touch-friendly, scaling to phone and tablet screens.

Stack

Stack (叠塔) is a one-tap timing game. A block slides back and forth above your tower, and a single tap drops it. Whatever hangs past the block below is sliced off, so each drop is only as wide as the part that lands flush — the goal is to build the tallest tower you can before a block misses completely.

How to play

Watch the block slide left and right above the top of the tower.
Tap the screen or press Space to drop the block.
The part that overhangs the block below is sliced off and falls away.
Land a near-perfect, flush drop to keep the full width.
Keep stacking as the blocks speed up — the run ends the moment a block misses the tower entirely.

Tips

Drop a touch early — the block keeps sliding while it falls.
A clean, full-width drop keeps you wide; sloppy drops whittle the tower down.
Four perfect drops in a row regrow the block — chase the streak.

Stack

叠塔(Stack)是一款单键操作的计时游戏。一块方块在你的高塔上方来回滑动,轻点一下即可把它叠落。任何伸出下方方块边缘的部分都会被切掉,所以每一次叠放只剩下与下方对齐的那一段宽度 —— 目标是在某块方块完全错过之前,把塔叠得尽可能高。

玩法

观察方块在塔顶上方左右滑动。
点击屏幕或按空格键把方块叠落。
伸出下方方块边缘的部分会被切掉、翻落而去。
叠出近乎完美、完全对齐的一落,即可保留整段宽度。
随着方块越来越快持续叠放 —— 一旦某块方块完全错过高塔,本局即告结束。

玩法技巧

可以稍微提前点 —— 方块在下落途中仍在继续滑动。
一次干净、足宽的叠放能让你保持宽度;马虎的叠放会把高塔一点点削窄。
连续四次完美叠放会让方块重新变宽 —— 追求这条连击。
