🏗️ 叠方块Stack Tower
在线叠方块（堆塔）小游戏：方块左右来回滑动，看准时机点击放下，和下面那层重叠的部分会留下、多出去的部分会掉落，塔会越叠越窄；正好对齐算“完美”，连续完美还能把方块变宽。越往上速度越快，一键操作，手机电脑都能玩，记录最高分。Play stack tower online: a block slides back and forth — tap to drop it, and only the part that overlaps the layer below stays while the overhang falls off, so the tower gets narrower. Land it exactly for a “perfect”, and perfect streaks widen the block again. It speeds up as you climb; one-button play on phone or computer, with a high score.
点击/轻触画面，或按 空格、回车、↓ 放下正在滑动的方块，P 暂停，N 重新开始。每放好一层得 1 分，完美对齐得 2 分；连续 3 次以上完美，方块会变宽一点。完全没对上就会倒塌。Click or tap the screen, or press Space, Enter or ↓, to drop the sliding block; P pauses, N restarts. Each layer scores 1 and a perfect landing scores 2; three or more perfects in a row widen the block a little. Miss the tower completely and it topples.
玩法说明与常见问题How to play & FAQ
「叠方块」怎么玩？How do I play Stack Tower?
塔底是一块宽方块。每一层都会有一块同样宽的新方块从左边或右边滑进来，你要在它和下面一层对齐时放下。放下后，只有和下面重叠的部分会留下来成为新的一层，伸出去的部分会掉下去，所以下一层会变窄。误差在几个像素以内算“完美”，宽度保持不变。层数越高滑动越快，直到你完全没对上为止。The tower starts with a wide base. For each layer a new block of the same width slides in from the left or right, and you drop it when it lines up with the layer below. Only the part that overlaps stays to form the new layer; the overhang breaks off and falls, so the next layer is narrower. Landing within a few pixels counts as perfect and keeps the full width. The higher you go the faster it slides — until you miss completely.
有什么技巧？Any tips?
别盯着移动的方块，而是盯着下面那一层的边缘，等滑动方块的边缘与它重合时立刻点击；保持节奏比反应速度更重要。方块变窄后更要稳，完美连击可以把宽度慢慢补回来。Watch the edge of the layer below rather than the moving block, and tap the moment the two edges meet — rhythm matters more than reflexes. When the block gets narrow, slow down; perfect streaks gradually win back width.
能在手机上玩吗？Can I play on a phone?
可以，整个游戏只需要点击屏幕一个操作，竖屏正好。切到别的应用时会自动暂停。Yes — the whole game uses a single tap, and it fits a portrait screen nicely. It pauses automatically when you switch apps.
