Fish Sort Puzzle rules

  1. Tap an exposed fish. Bright bubbles are playable; dim bubbles have another tile above them.
  2. Watch the holding tray. Each selected creature occupies one of seven spaces.
  3. Make a triple. Three identical creatures clear automatically and count toward the aquarium order.
  4. Reveal lower layers. Removing top bubbles opens new choices in the same stack.
  5. Clear the board. Remove every fish to complete the level and unlock the next one.

Strategy for a nearly full tray

Start by counting pairs. If two clownfish are already in the tray, search the exposed bubbles for a third before selecting a new creature type. A completed triple creates three empty spaces at once.

When no immediate match is available, prefer a bubble that reveals one of your existing tray types. The small stack counter shows when several tiles remain below a bubble.

When to use Rescue 3

Rescue is strongest when the tray contains three unrelated early picks. Move them aside, complete one or two triples, then return the rescued creatures when their partners appear.

Try the rules now

The first level uses only a few creature types and a short solution sequence. Use it to learn the bubble layers and automatic triple clear.

Every level is generated from a known clearing order, so there is always a solution.
