RapidSort: Water Sort Puzzle

Pour coloured water between tubes until every colour has one to itself. Take your time and think through every pour, or switch to Blitz when you want the game to move as fast as you do.

PLAY YOUR WAY
Classic mode gives relaxed players room to plan, undo and use hints. Every board is clear, readable and ready whenever you are.

BLITZ FOR FAST & ADVANCED PLAYERS
Study the board, tap Go, and race. Every move happens instantly—no pouring animation and no waiting between taps. Your time is your score, making Blitz a responsive challenge for experienced solvers and speed-focused players.

EVERY PUZZLE HAS A PERFECT SOLUTION
Not "probably solvable"—every board is verified by a solver before you see it, and every board has a known best answer. Beat it in that many moves and you earn three stars. Nothing is random, unfair or impossible.

DAILY CHALLENGE
One board, the same for everybody, every day. Build a streak and share your result.

BOSS LEVELS
Every tenth level brings taller vessels—five layers instead of four, the same colours, and much more to plan. Beat one and its odd little specimen is sealed onto your collection shelf.
