In the frame
A yellow seahorse holds on to a blade of seagrass with its curled tail. A meadow of green seagrass fills the lower half, and teal water full of tiny floating specks fills the top.
This dive turns the picture into a 4 × 4 slide puzzle: 15 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 yellow seahorse and its curled tail.
- Save for last: the teal water. About 34% of the frame has little detail, mostly in the top 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.
- For the last two rows, work column by column, two tiles at a time.

How deep it goes
Depth 3 of 5 — a steady dive.
Wall dives drop off into bigger boards, where the plain parts of a picture start to slow you down.
