In the frame
Five bottlenose dolphins swim together just below the rippled surface, sunbeams fanning out between them. Below them the water fades to a deep, plain blue.
This dive turns the picture into a 5 × 5 slide puzzle: 24 tiles and one empty space. The shuffle is fixed, so everyone starts from the same board, and it is always solvable.
Dive plan
- Start with the easy part: the dolphins and the bright ripples at the top.
- Save for last: the deep blue water below the dolphins. About 45% of the frame has little detail, mostly in the bottom third, and those pieces look alike.
- Finish the top row first, then the left column; the puzzle shrinks to a smaller board each time.
- Switch on the numbers if two tiles look alike — they show where each tile belongs.
- Look-alike tiles are where the numbers help most: plain water or sand gives few clues about order.
- A 5 × 5 board is a real workout; if you get stuck, the hint suggests a move or highlights a misplaced tile.

How deep it goes
Depth 4 of 5 — a demanding dive.
Deep dives are the longest in the logbook: the largest board each game gets in the numbered dives.
