In the frame
A bright orange damselfish swims among swaying kelp fronds. A rock crusted with pink algae and small orange anemones fills the lower right, and green-blue water glows behind the kelp.
This dive cuts the picture into 40 square tiles on a 8 × 5 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 fish and the pink rock with its anemones.
- Save for last: the hazy green water behind the kelp. About 22% 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, 39 swaps or fewer finish all 40 tiles.
- Most tiles here hold a recognisable feature, so find their spots by comparing them with the preview.
- On a big board, finish one area at a time instead of chasing single tiles across the board.
