Dive 87 · Kelp Forest

Orange damselfish in the kelp

Filling the tank…

In the frame

A bright orange damselfish swims among swaying kelp fronds. A rock crusted with pink algae and small orange anemones fills the lower right, and green-blue water glows behind the kelp.

This dive cuts the picture into 70 pieces on a 10 × 7 grid: 30 border pieces and 40 inner pieces. The cut is fixed, so every player gets exactly the same pieces.

Dive plan

  1. Start with the easy part: the orange fish and the pink rock with its anemones.
  2. Save for last: the hazy green water behind the kelp. About 22% of the frame has little detail, mostly in the top third, and those pieces look alike.
  3. Switch on Edges to keep only the 30 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. With this much detail you can build small islands around single features and join them to the frame later.
  6. Group the loose pieces by colour before you start joining them; it saves a lot of searching.

How deep it goes

Depth 3 of 5 — a steady dive.

Wall dives drop off into bigger boards, where the plain parts of a picture start to slow you down.
