Butterflyfish at a red sea fan

Two yellow and white butterflyfish in front of a large red sea fan

Filling the tank…

In the frame

Two yellow and white butterflyfish with fine dark lines swim in front of a big red sea fan. Black and yellow feather stars cling to the reef below, and the left side of the picture is open deep blue water.

This dive cuts the picture into 24 pieces on a 6 × 4 grid: 16 border pieces and 8 inner pieces. The cut is fixed, so every player gets exactly the same pieces.

Dive plan

  1. Start with the easy part: the red sea fan and the two yellow fish.
  2. Save for last: the open blue water. About 33% of the frame has little detail, mostly on the left side, and those pieces look alike.
  3. Switch on Edges to keep only the 16 border pieces on the table, and build the frame first.
  4. Press Sort to tidy the loose pieces into rows around the board, border pieces nearest — handy once the frame is done.
  5. In the plain areas, match pieces by shape: on a 6 × 4 grid every inner piece has a tab or a blank on each of its four sides.
  6. At this size most pieces show something recognisable — a good dive for a few relaxed minutes.

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.
