点一根试管，最上面的球会抬起来；再点目标试管就倒进去。只能倒在颜色相同的球上面或者空试管里，每根试管最多装 4 个球；同色相连的几个球会一起倒过去。每个球上还有不同的符号，方便区分颜色。键盘：数字 1–9/0 选试管，U 悔棋，H 提示，R 重来。Tap a tube to lift its top ball, then tap the target tube to pour. You can only pour onto a ball of the same colour or into an empty tube, and a tube holds four balls; a run of same-coloured balls moves together. Each colour also carries its own symbol. Keyboard: 1–9/0 pick tubes, U undo, H hint, R restart.
玩法说明与常见问题How to play & FAQ
「彩球排序」怎么玩？How do I play Ball Sort Puzzle?
每种颜色有 4 个球，被打乱装在几根试管里，另外还有两根空试管当“周转”。每一步把一根试管顶上的球倒进另一根：目标试管要么是空的，要么最上面的球颜色相同，而且不能超过 4 个。当每根试管里都是同一种颜色的 4 个球（或者是空管）时就完成了。每局开局前都用程序验证过可以解开。Each colour has four balls, shuffled across several tubes, plus two empty tubes to work with. Each move pours the top ball(s) of one tube into another: the target must be empty or have the same colour on top, and may hold at most four balls. You win when every tube is either empty or holds four balls of one colour. Every deal is checked by a solver before you get it.
卡住了怎么办？What if I get stuck?
可以无限悔棋，也可以点「提示」——程序会从当前局面重新搜索一条解法，并用黄框标出下一步该倒哪两根。如果提示说已经无解，就悔几步或点「重来」。Undo as much as you like, or press Hint: it searches for a solution from the current position and frames the two tubes for the next pour in yellow. If it says there is no solution any more, undo a few moves or restart.
有什么技巧？Any tips?
尽量保留一根空试管，别轻易把它填掉；优先把同色的球叠在一起，越早凑出一根完整的同色试管，后面就越轻松。Try to keep one tube empty as long as possible, stack matching colours first, and finish a full single-colour tube early — everything gets easier after that.
