Flow Link

Flow Link is a path-packing puzzle game. The board is a square grid sprinkled with pairs of coloured dots. Your job is to draw a single ribbon for each colour that runs from one dot to its matching partner — and to do it in such a way that every cell of the board ends up covered by some ribbon. Paths cannot cross each other, and you only have one continuous drag per colour, so a winning solution requires both finishing every pair and tiling the entire grid. The interaction is the heart of the game: every drag grows a ribbon under your finger, and pressing on any cell along an existing ribbon truncates that ribbon back to that cell — implicit undo, no buttons needed.

How to play

1. Press on a coloured dot, then drag along the grid one cell at a time. A ribbon of that colour grows along your drag.
2. Drag onto the matching dot of the same colour to close that pair. A closed pair pulses to confirm.
3. If your ribbon goes the wrong way, drag back over it — your ribbon shortens to wherever your finger is.
4. If you cross onto another colour's ribbon, that ribbon gets shortened back to make room for yours.
5. You win when every pair is connected AND every cell of the board is covered by some ribbon.

Tips

• Plan corners first: cells in the corners of the board only have two adjacent neighbours, so the ribbon passing through them has only one possible exit direction. That often forces the answer.
• Pressing your starting dot resets that whole ribbon — useful for a fresh attempt without disturbing the others.
• If you are stuck, press H (or tap the hint button) to reveal one cell of the next unfinished path. You get up to three hints per puzzle, but a hint-less solve scores a better personal best.

FAQ

Is Flow Link free to play?

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

How do I undo a wrong move in Flow Link?

There is no undo button — dragging back over your own ribbon shortens it to wherever your finger is. Pressing the starting dot resets that ribbon completely.

Why doesn't my puzzle complete even though every pair is connected?

Flow Link requires every cell of the board to be covered by some ribbon, not just every pair to be connected. If the win doesn't fire, look for an empty cell and reroute one of your paths to pick it up.

What's the difference between Flow Link and Aurora?

Aurora is a single-stroke Euler-path puzzle on a stylised star graph — one continuous line, abstract layout. Flow Link is on a square grid with multiple coloured pairs, and the win requires both linking and tiling. They share the spirit of 'draw one path' but use very different cognitive tools.

Flow Link

连线填路(Flow Link)是一款路径填充类谜题。棋盘是一块正方形格子,上面散落着成对的彩色端点。你要为每个颜色画一条不间断的彩带,从一个端点连到同色的另一个端点 —— 同时让每个格子都被某条彩带覆盖。彩带之间不可交叉,每个颜色只允许一笔到位,所以通关同时需要「连通每一对」与「铺满整张棋盘」。整套交互是这款游戏的精髓:拖动时彩带在指尖延伸,而按下任何已有彩带上的格子会让那条彩带回缩到这一格 —— 这是隐式的撤销,无需按钮。

玩法

1. 按住一个彩色端点,沿网格一格一格拖动,同色彩带会在你的指尖延伸。
2. 拖到同色的另一个端点上即可闭合这一对,闭合时会有脉冲反馈。
3. 如果走错了,拖回自己的彩带上 —— 彩带会缩短到你手指所在的格子。
4. 如果你跨到了另一种颜色的彩带上,那条彩带会回缩,把这格让给你。
5. 当所有配对都闭合,并且每个格子都被覆盖时,即获胜。

玩法技巧

• 先规划角落:角落格子只有两个相邻邻居,经过角落的彩带只有唯一一条出路,这往往能锁死答案。
• 按你的起点端点可以重置该色彩带 —— 想重新尝试某色时很有用,且不会影响其他颜色。
• 卡关时按 H(或点提示按钮)可揭示下一条未完成彩带的一格。每关上限 3 次提示,但不使用提示通关会获得更好的个人最佳。

常见问题

连线填路是免费的吗?

是的。连线填路在浏览器中免费运行,电脑和手机均可,无需安装、注册或下载。

怎么撤销错误的一步?

没有撤销按钮 —— 拖回自己的彩带即可让它缩短到你手指所在的位置。如果要彻底重画一条彩带,按一下它的起点端点即可。

每对都连上了为什么还不通关?

连线填路要求每个格子都被覆盖,而不仅仅是每对都连通。如果没胜利,看一下棋盘上是否有空格,把某条彩带绕过去把它捎上即可。

连线填路和 Aurora 有什么区别?

Aurora 是图论上的一笔画(Euler path),抽象的星图、一条连续的线。连线填路在方格网上,有多个颜色对,胜利同时需要连通和铺满。共享「画一笔」的精神,但所需的思考方式很不一样。
