About Marble Sort!
Marble Sort is a free, deeply satisfying color-sorting puzzle with a conveyor-belt twist. Marbles roll down the belt one after another, and your job is to route every single one into the box that matches its color - three marbles per box, every box filled, level complete. It sounds trivial. Then level 15 adds a third color. Then a fourth. The belt speeds up, the boxes fill unevenly, and what began as a relaxing tap-along becomes a genuine test of reading ahead: the best players watch the incoming marbles, not the boxes, and plan two or three sorts before each marble arrives. With 120 levels of procedurally generated puzzles, the game scales beautifully from a calm color-matching toy for kids to a genuinely tricky sorting challenge for puzzle veterans - colors ramp from 2 up to 6, and belt speed climbs steadily with your progress. There are no timers breathing down your neck and no fail states, so the experience stays on the relaxing side of arcade even when the belt is flying: a wrong sort just means shuffling your plan, not losing the run. Satisfying sound effects punctuate every correct sort, progress and level unlocks are saved automatically on your device, and the whole game runs in any modern browser with no download, no installation and no account. It is the perfect coffee-break game - playable in 30-second slices or hour-long sessions - and a wonderful way for younger players to practice color matching and planning. Tap in, find the rhythm of the belt, and sort your way through all 120 levels of marble-moving satisfaction.
