In the frame
A large conch shell with a glossy pink lip lies on rippled sand next to two orange sea stars and three round sand dollars. A net of sunlight shimmers over the bottom.
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 conch shell and the two orange sea stars.
- Almost every part of this frame has detail. The least distinct part is the sunlit sand at the top, 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.
