In the frame
Golden-brown kelp rises in tall columns from a dark rocky floor towards the light. Bright sunbeams slant between the stalks, and small fish drift in the blue gaps.
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 bright kelp stalks and the sunbeams.
- Almost every part of this frame has detail. The least distinct part is the dark rocks on the floor, 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.
