In the frame
Seen from above, a clear rock pool holds two orange and two purple sea stars among a dozen round green anemones. Pink algae, small snails and pebbles fill every gap.
This dive cuts the picture into 24 square tiles on a 6 × 4 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 orange sea stars and the green anemones.
- Almost every part of this frame has detail. The least distinct part is the dark corners of the pool, and even that has texture to go on.
- 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, 23 swaps or fewer finish all 24 tiles.
- Most tiles here hold a recognisable feature, so find their spots by comparing them with the preview.
- Before each swap, compare the tile with the preview; a careful swap beats two quick ones.

How deep it goes
Depth 2 of 5 — an easy dive.
Wall dives drop off into bigger boards, where the plain parts of a picture start to slow you down.
