Color Sort
Sort each color into its own tube. Racing, action, puzzles and duels to enjoy on phones or computers.
Gather each color into a full tube, at your own pace. Press a tube button to choose the source, then another for the destination. Keys 1–8 select tubes. Escape clears selection; Undo or U takes back one move. Tab moves through native buttons; Enter or Space activates the focused button. Names and symbols repeat the colors: neither color recognition nor hearing is required. Each tube holds 4 units. Pour the whole contiguous top group of one color, limited by available space, into an empty tube or onto the same color. You solve the puzzle when every nonempty tube is full and contains one color. There is no timer or forced loss: if stuck, undo or replay. Levels keep progressing, with 3 to 6 colors. Solving a level unlocks the next. Replay restarts the exact current puzzle; New Game starts level 1 and keeps earned unlocks and best move counts. A valid old grid and undo history are preserved, including high levels. Old records remain separate: new puzzle layouts have changed, so their scores cannot be compared. Original music at 68 beats per minute blends soft crystal keys and glass resonance. Selection, pouring, a completed tube, undo, and a quiet invalid move have their own cues. Music and effects have separate volumes with true zero; global mute silences both. Sound starts only after your action and stops when paused or in the background.
