Color Sort

Move one piece at a time

Select a tube, then an empty destination or a tube topped by the same color with space remaining. This build moves only the top piece on each action. It does not pour an entire matching group as Chromatic Flow does, so a transfer of several pieces takes several moves.

Preserve an empty tube when it helps uncover a needed color. For example, if a red piece covers blue pieces, moving that red piece to a matching red stack can expose blue without using an empty tube. Compare the tops of the other tubes before moving a whole sequence piece by piece.

Finish the colors, not just the top row

All nonempty tubes must be full and contain a single color to solve the board. Seeing matching colors on every top is not sufficient if different colors remain underneath. Work toward completed tubes while leaving enough room to rearrange the mixed ones.

Choose a difficulty for regular play or use the Daily puzzle based on the UTC date. Hints and Undo support experimenting with a position. Native continuation uses this browser’s stored progress, so changing devices or clearing site data can remove the board you were working on.

How to play
