Marble Color Sort — marble sorting on a conveyor belt
At the top, there are trays filled with colorful marbles. You tap a tray, and the marbles roll onto a round conveyor belt that keeps spinning. At the bottom, boxes are waiting: each one holds three marbles of the same color. A full box disappears and frees up space. Color sorting is also in Marble Sort, but here the big thing is the moving conveyor and timing your move.
Why you can’t rush it
Each tray holds six marbles of one color, enough for two boxes. The trays that go first are the ones at the front of the line. If you release a color with no matching box waiting below, the marbles keep circling and take up space. If the conveyor fills up and there are no suitable boxes, the level is lost.
The marbles fall with physics: they bounce and collide with each other, so they don’t always land where you expect. With each level, there are more colors on the conveyor, and you have to keep track of several streams at once.
