In the frame
A giant clam fills most of the frame, its wavy shell open to show an electric-blue mantle dotted with dark spots. Branching and lumpy corals in beige, pink and lilac surround it.
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 wavy, dark-rimmed edges of the shell.
- Almost every part of this frame has detail. The least distinct part is the deep blue middle of the mantle, 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.
