Prism Pour: a five-pour opening and a plan for harder bottles
The useful question in a water-sort puzzle is not simply which colors match. Ask what the pour will uncover, and where the newly exposed color can go. Prism Pour has 36 fixed starting layouts, so an opening you learn can be repeated on the same level.
Why a pour sometimes stops
Each bottle has room for four layers. You can pour into an empty bottle or onto the same top color. All touching layers of that top color travel together, but only as many as the destination can hold. For example, two coral layers above mint will both move into an empty bottle. If the destination already holds three coral layers, only one can move. A bottle with spare capacity still rejects a different top color.
Level 1, numbered from left to right
From the untouched opening shown above, use this sequence: 1 → 3, 2 → 1, 2 → 3, 2 → 1, 2 → 3. The first pour moves the two coral layers out of bottle 1. Its exposed mint accepts the top layer from bottle 2. Moving bottle 2’s coral onto bottle 3 exposes another mint layer, which also joins bottle 1. The last coral completes bottle 3. Bottles 1 and 3 are now full and single-color; bottles 2 and 4 are empty. These five pours meet the level’s three-star target. Restart first if you want to follow this exact sequence.
Use an empty bottle to uncover a route
On a harder board, inspect the layer immediately below each available top group. Moving that group is especially useful when the exposed color already has a destination. Filling every empty bottle with a different temporary color can leave you unable to uncover anything else. Prefer a pour that consolidates a color or empties a mixed bottle over one that merely moves the same problem sideways. This is a planning heuristic, not a rule that every solution must follow.
Undo is part of the puzzle
There is no timer. If a move closes a route, Undo restores the previous board and reduces the pour count. Hint looks for a route from your current position; it does not merely replay the opening solution. A stuck position and a search that reached its limit are reported separately. Try undoing an earlier choice before restarting the entire puzzle.
Stars and saves
The three-star target is the length of a verified solution, not a claim that no shorter solution exists. Up to five extra pours earns two stars; any completed board earns at least one. The unfinished board and undo history save in this browser. Clearing site data removes that save, and another device does not automatically receive it.
