In the frame
A white lighthouse with a red lantern stands on a grassy, rocky headland. Waves break white against the rocks below, and a blue sky with soft clouds and a few gulls fills the top.
This dive cuts the picture into 12 square tiles on a 4 × 3 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 lighthouse and the white surf on the rocks.
- Save for last: the clear blue sky. About 38% 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, 11 swaps or fewer finish all 12 tiles.
- Place tiles with an outline, a fin or an edge first; the plain ones are easier once only a few spots remain.
- With so few tiles, try to finish without opening the preview.

How deep it goes
Depth 2 of 5 — an easy dive.
Snorkel dives are the shallow end of the logbook: small boards with pieces big enough to read at a glance.
