Flow Link

About Flow Link

The platform's first deduction / path-routing logic puzzle (the Flow-Free / Numberlink family). A grid holds pairs of colored dots; drag a pipe from each dot to its match. Paths may never cross, and you must fill every single cell — the board clears only when all pairs are connected AND no cell is left empty. Rising-size boards from gentle 5x5 grids to dense 9x9, with best-time and a no-reroute Perfect badge to chase.

How to play

Drag from a colored dot to its same-color twin to lay a path (touch-drag on mobile, click-drag on desktop). Paths can't cross — dragging through another color's path erases it onward, so just re-drag to fix any mistake. The board clears only when every pair is connected AND every cell is filled: if it won't clear, the empty cells gently pulse. Tap Reset (or R) to clear, Undo (or Z) to take back the last path, Next (or N / Space) to advance. Solve fast with no re-routes for 3 stars and the Perfect badge.
