About the game

Pour, sort, and clear the board.

Klack Sort keeps it pure: each tube holds a stack of coloured blocks, and your job is to pour them from tube to tube until every colour sits together. Undo mistakes, take a hint, or add an extra tube to work through the trickier boards. It plays fully offline and asks nothing of you but a clear head.
