Marble Sort

Marble Sort is the definitive color-sorting relaxer: tubes of scrambled marbles, and only the top group can pour. Move same-color runs into matching tubes or empty ones until all four of a kind sit together.

12 levels from 3 colors to a full 10-color laboratory, with group-move pours, undo, and an extra-tube booster when you paint yourself into a corner.

Tap a tube to select it, then tap a destination: the top group of same-colored marbles pours if the destination is empty or has the same color on top and space left. Fill every tube with 4 same-colored marbles to win.

Tap tubes to select and pour.
