How to play

Sort mixed marbles so every non-empty tube holds one color. Marble Sort includes three verified-solvable layouts, source and destination selection, legal-move feedback, move and mistake counters, Undo, mouse, touch, and keyboard controls, accessible tube labels, fullscreen play, and instant restart. Choose a board size, make your move, and use Restart whenever you want a fresh game.

Strategy tips

  • Expose matching colors near the tops of several tubes before committing scarce empty space.
  • A legal destination must be empty or have the same color on top, and no tube can hold more than four marbles.
  • Use Undo or press U to reverse a legal move without resetting the whole puzzle.
