Water Sort — Free Color Sorting Puzzle Game

Water Sort is a calm logic puzzle: bottles hold layered colors, and you can only pour the top run of a color into an empty bottle or onto the same color. Sort every color into its own bottle in as few pours as you can.

60 verified puzzles, three chapters

  • Warm-up (1–20): 2 to 5 colors, including three interactive tutorials.
  • Full shelf (21–40): 6 to 8 colors, tighter interleaving.
  • Deep mix (41–60): 8 to 10 colors, deeper layering.

Every level was generated and then verified by a real-rule solver: each one is solvable, and the in-game "fewest possible" count is a proven BFS minimum, not a guess. Levels are deduplicated against color renames and bottle reordering — no palette swaps padding the count.

Tools that respect your brain

  • Undo and restart are free — using them or hints marks the run as Assisted; clean runs are tracked separately.
  • Hint searches from your actual board for a pour that leads to a finish (250 ms budget; if it can't find one in time, it says so instead of guessing).
  • View solution walks through the reference solve as a demo that never counts as your clear.
  • Every color carries a symbol as well as a hue, so puzzles never rely on color vision alone.

Daily puzzle and challenges

A daily puzzle rotates at 00:00 UTC for everyone. Finish a level and you get a result text with a challenge code like ATG1-WS-r1-c1-l12 — a friend enters it to play the exact same level from scratch.

Questions

Are the puzzles always solvable?

Yes. Every one of the 60 levels was verified by a solver that plays by the exact same rules as the game, and the "fewest possible" number shown in the HUD is a proven BFS minimum for that board. If you reach a dead end, undo and restart are always available.

What counts as one move?

One legal pour from one bottle into another — regardless of how many units move. Selecting, canceling and invalid taps never count.

When is a run "Assisted"?

When you use a hint or an undo. Assisted clears still earn stars and count as completing the level, but they're recorded separately from clean runs so best-move comparisons stay fair.

How does the hint work?

It searches from your current board (not from the start) for a pour that leads to a complete solution, within a 250 ms budget, and highlights the source and target bottles. If the search doesn't finish in time it says so honestly — it never suggests a known dead end just because it's legal.

What is the daily puzzle?

One level per day, the same for everyone, chosen by the UTC date and changing at 00:00 UTC. You can retry it as often as you like.

What are challenge codes?

After clearing a level you can show a result text like Water Sort · Level 12 · 24 moves · 03:18 · No assists · ATG1-WS-r1-c1-l12. The final code replays that exact level for anyone who enters it. Scores are self-reported for friendly competition, not certified rankings.

Does it work for colorblind players?

Yes — every color also has a distinct symbol printed on each segment, so sorting never depends on hue alone.
