In the frame
A flat rocky shore stretches to the sea under a sunset of orange and pink clouds, with the sun sitting on the horizon. Dozens of shallow pools mirror the sky; the largest lies in the foreground.
This dive turns the picture into a 4 × 4 slide puzzle: 15 tiles and one empty space. The shuffle is fixed, so everyone starts from the same board, and it is always solvable.
Dive plan
- Start with the easy part: the sun on the horizon and the large pool in front.
- Save for last: the smooth sky and the flat rock shelf. About 16% of the frame has little detail, mostly in the top third, and those pieces look alike.
- Finish the top row first, then the left column; the puzzle shrinks to a smaller board each time.
- Switch on the numbers if two tiles look alike — they show where each tile belongs.
- The picture is busy enough that neighbouring tiles can usually be told apart without numbers.
- On a 4 × 4 board, leave finished rows alone and work only in the rest of the board.

How deep it goes
Depth 2 of 5 — an easy dive.
Reef dives sit in the middle: enough pieces to need a plan, never so many that a phone screen feels crowded.
