Pixel Flow is a calm logic puzzle: paint every square of a hidden pixel picture with one single, unbroken stroke, then watch the finished image bloom into colour.
Start on the glowing square and drag (or use the arrow keys) to paint. The stroke moves up, down, left or right and must cover every square of the picture exactly once.
You can't enter a square that's already painted. Drag back along your line or press Undo to step back, and use Reset to start over whenever you like.
Later pictures add numbered squares, which must be painted on exactly that move, and bridges, which you cross twice: once sideways and once up or down.
Earn one star for finishing, one for not resetting and one for not using hints. You start with 3 hints and earn another for every 5 new pictures you complete.
Yes. Every one of the 60 pictures was checked by a solver that traced a complete one-stroke path, so each level can always be finished.
Nothing bad. Step back along your trail, undo the last segment or reset the picture. There are no lives or timers; the puzzle itself is the challenge.
A hint shows the next correct direction, or points out where your path went wrong. You start with 3 and earn one more for every 5 new pictures you finish.
Yes. Solved pictures, stars, hints and settings are stored on your device, so you can close the game and continue later.
