About
Marble Sort is a color-sorting puzzle: glass tubes hold up to 4 marbles each and start with mixed marbles, plus 2 empty tubes. Tap a tube to lift its top marble, then tap another tube to drop it; a drop is allowed only onto an empty tube or onto a marble of the same color with room left, and a run of same-colored top marbles moves together. A level is solved when every tube is empty or holds a single color. Levels are generated from the level number (the same for every player), every level is checked solvable, and difficulty rises from 3 to 9 colors. Each color also carries a symbol so marbles can be told apart without relying on color. Unlimited undo, restart, and one extra tube per level; keyboard: 1-9/0 select tubes, U or Z undo, R restart.
