Knot Flow

Connect every colour across the grid — and where two pipes meet, send yours diving underneath in a clean over-under weave.

How to play

Each board has pairs of matching colored dots. Drag a path from one dot to its partner so every colour is linked. The twist is depth: paths may cross, and when they do, the pipe you draw tucks under the one already there, letting you knot routes together on two layers.

• Trace from a dot through adjacent cells to its matching dot to complete that colour.
• Cross an existing pipe and yours automatically dives one layer under it.
• Connect every colour to solve the board; fewer moves scores higher.
• Tap any laid pipe to clear that colour and reroute it.

Controls

• Desktop: click and drag from a dot to draw its path; tap a pipe to clear it; use the Clear button to reset the board and the speaker icon to mute.
• Phone & tablet: drag your finger from a dot to its match; tap a pipe to clear it — fully touch-friendly.

Game modes

• Daily: one shared puzzle each day, separately ranked.
• Levels: a hand-built pack of boards that grow in size and colour count.

Tips & strategy

• Run border colours along the edges first to free up the crowded middle.
• Plan your crossings — a deliberate dive can untangle a board that looks blocked.
• Shorter, tidier routes mean fewer moves and a better score.

About Knot Flow

Knot Flow is an original free browser game that reinvents the flow-connection / pipe-linking puzzle genre with a second layer, so crossing paths weave over and under instead of blocking. Built in-house for PlayPendium with a daily board and a progressing level pack.
