Water Sort exact-par puzzles, Daily archive & recovery tools
Sort every color into a single tube. The frozen source bank keeps an independently verified minimum-move solution; V0.331 adds repeatable Daily browsing and practical recovery tools without weakening that trust.
Choose a tube, then choose a legal destination.

V0.201 Solve Quality & Repeatability Lab
Inspect what each pour changed, compare a solve with the verified exact par, repeat the same fixed 5-color board, then train the weakest pattern. All evidence stays in this browser.
Play a legal pour to build local move evidence.
Fixed Benchmark · same 5-color board
The same deterministic Standard board is used every clean run. Its par is the exact BFS minimum stored by the source bank. Hint or tab interruption excludes the run from Clean 5.
Ready for Fixed Benchmark or Adaptive Drill.

How to play & exact-par rules
Pour the whole top block
A legal move transfers as much of the matching top-color block as the destination can hold. You cannot pour onto a different color.
Two empty tubes are working space
Each level includes two empty tubes. Good solves use them as temporary buffers rather than filling them without a plan.
Exact par, not a guess
The frozen source bank stores an exact minimum move count found by breadth-first search. Seed transforms preserve that move count.
Undo stays Clean
Undo and Restart are normal puzzle controls and do not mark a solve Assisted. Hint does because it identifies a legal next move from a solver.
Color-blind symbols
Every color also carries a letter symbol. The labels are visible by default and can be toggled without changing the puzzle state.
Daily Water Sort
The Daily puzzle is date-stable and separate from Today’s 6. Its history, streak and completion restore live only in browser-local storage.
