中间带 💧 的是水源。点击一节水管把它顺时针转 90°（电脑上右键逆时针转），已经和水源接通的管道会变成蓝色，末端的圆点变绿表示水龙头有水了。所有水管都变蓝、没有任何开口对着空处就过关。键盘：方向键移动选框，回车 顺时针，Z 或 Shift+回车 逆时针，H 提示。The 💧 tile in the middle is the source. Click a pipe to turn it 90° clockwise (right-click turns it anticlockwise on a computer). Pipes connected to the source turn blue, and the round outlets at the ends turn green once water reaches them. Make every pipe blue with no open ends pointing at nothing to win. Keyboard: arrows move, Enter turns clockwise, Z or Shift+Enter anticlockwise, H hint.
玩法说明与常见问题How to play & FAQ
「接水管」怎么玩？How do I play Pipe Connect?
棋盘上每个格子都是一节水管：直管、弯管、三通或末端水龙头，它们都被随机转乱了。你只能旋转，不能移动。目标是把所有水管连成一张从中央水源出发、覆盖全部格子的管网，每个开口都要和相邻水管对接，不能有漏水的口子。每局都由随机生成的树形管网打乱而来，所以一定有解。Every cell holds a pipe — a straight, a bend, a T-junction or an end outlet — and they have all been rotated at random. You can only rotate them, not move them. Join them into one network that starts at the central source and reaches every cell, with every opening meeting a neighbouring pipe and no leaks. Each puzzle is made by scrambling a randomly generated tree of pipes, so it is always solvable.
从哪里开始比较容易？Where is the best place to start?
先看边和角：贴着边的管道开口不能朝外，角上的弯管只有一种方向能放。接着处理末端水龙头和直管，它们的方向选择最少。确定了的格子一般就不用再动了。Start at the edges and corners: openings can never point off the board, and a bend in a corner has only one possible orientation. Next fix the outlets and straight pipes, which have the fewest options. Tiles you have settled rarely need to move again.
提示会直接帮我转吗？Does the hint rotate the tile for me?
不会，提示只会用黄框标出一节还没转到正确方向的水管，转几次由你自己决定。No — the hint only frames one pipe that is not yet in its correct orientation; how far to turn it is up to you.
