Water Sort.
A little colour therapy. Pour, plan and give every colour its own glass tube.
Keyboard and accessible move buttons
Use Tab and Enter to select these controls. On Block Puzzle, select a piece here, then use arrows and Enter on the focused board.
How to play Water Sort
Separate the colours into full, single-colour tubes. An empty tube is allowed at the finish. Check each vessel capacity. 300 levels increase from three to nine colours, with two extra vessels. From level 15 the central jar holds six layers; other vessels hold four. Every generated starting board has a verified route to a solution.
Computer, mobile and keyboard controls
Select a non-empty source, then a destination that is empty or has the same top colour. The entire matching top run pours until it ends or the destination fills. Tap the source again to cancel your selection.
Mouse clicks and touchscreen taps use the same rules. Open the accessible controls for HTML move buttons. Escape pauses the focused board; Z undoes a move before the run ends. Changing tabs pauses play.
Tips and strategy
Keep an empty tube available when possible. Free buried colours before sealing too many tubes. Undo is free. A highlighted legal move is a suggestion, not a promise that it improves your position; undo and retry if a route stalls.
Score and Puzzle Coins
10 points per legal pour, plus 500 + 100 × level for solving. Undo restores the old score. This is a relaxed game without a time limit.
A finished run needs at least 10 active seconds to earn final coins. The reward is floor(score / 30) + 2 per full 30 active seconds, limited to 5–50 coins. Short runs still save their score. Time paused, hidden or idle for more than a minute is not counted.
Puzzle Coins belong only to this portal. Puzzle coins unlock permanent visual themes; hints and undo are free. Themes do not change the rules.
Saving and your profile
Won and lost runs save automatically. Use End & save to stop early. Your unfinished board resumes when you return. Guest coins and records stay in this browser. Your wallet and scores stay separate from Arcade. The leaderboard shows your own results, not other visitors.
