A bright, brain-teasing pipe puzzle on a calm dark board. Link every pair of colored dots with a flowing neon pipe — but there is a twist: your pipes have to fill the whole grid, with no empty cells and no crossings. Simple to pick up, wonderfully tricky to master.

HOW IT WORKS
Each board is dotted with pairs of colored endpoints. Press a dot and drag across the grid to reach its twin, drawing a glowing pipe as you go. Do it for every color, cover every last cell, and the level lights up complete.

ONE SIMPLE RULE, ENDLESS PUZZLES
Pipes cannot cross, and every square must be filled. That single constraint turns a handful of dots into a genuine logic puzzle — there is almost always one elegant route, and finding it is the whole joy.

TEN LEVELS THAT GROW WITH YOU
Ten hand-built stages, from a gentle 5×5 Warm Up to a dense 9×9 Grandflow. Grids get bigger and colors multiply, so the challenge rises exactly as fast as your confidence does.

SMOOTH, FORGIVING CONTROLS
Drag back along a pipe to shorten it, grab a dot to redraw a color from scratch, Undo a step, or Clear the board and start fresh. There are no mistakes to punish you — just puzzles to solve at your own pace.
