In the frame
Dozens of purple sea urchins cover a rocky seabed between tufts of red algae, and an orange sea star lies in the middle. Kelp stalks rise into teal water in the background.
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 sea star and the purple urchins around it.
- Almost every part of this frame has detail. The least distinct part is the teal water between the kelp stalks, 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, 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.
