In the frame
Two orange anemonefish with white bands nestle in a large anemone whose tentacles fill the right half of the frame. Above the brown coral boulders on the left, small blue fish swim in sunlit water.
This dive cuts the picture into 15 square tiles on a 5 × 3 board and shuffles them. Swap two tiles at a time until the picture is whole; tiles that reach their home spot lock.
Dive plan
- Start with the easy part: the two orange fish and their white stripes.
- Save for last: the sunlit blue water. About 21% of the frame has little detail, mostly in the top third, and those pieces look alike.
- Swap each tile straight to its home spot; it locks there, and the tile you displaced is the next one to place.
- If every swap sends a tile home, 14 swaps or fewer finish all 15 tiles.
- Most tiles here hold a recognisable feature, so find their spots by comparing them with the preview.
- Fix the corners first: they are the easiest tiles to place by eye.

How deep it goes
Depth 2 of 5 — an easy dive.
Reef dives sit in the middle: enough pieces to need a plan, never so many that a phone screen feels crowded.
