About Marble Sort

You tap trays to drop colored marbles onto a moving conveyor belt, then sort them into holders by matching their colors. Each holder needs exactly three identical marbles to complete. Your goal is to clear every tray on the level without letting the belt overflow or placing marbles in the wrong spots.

The game rewards careful planning because one wrong move can jam the whole system. You need to think a few steps ahead, watch the belt's flow, and decide which tray to release next. The simple mechanics and smooth sorting action make it easy to pick up, while later levels on Poki Games demand sharper strategy and timing to master.
