Dive 20 · Blue Edge

Whale shark below the surface

Filling the tank…

In the frame

A whale shark covered in white spots and pale stripes swims just below the surface, with a group of small yellow-striped fish leading the way in front of its mouth. Sun rays slant down through turquoise water.

This dive leaves all 6 tiles of a 3 × 2 board in place but rotates them by 90, 180 or 270 degrees. Tap each tile until the whole picture stands upright.

Dive plan

  1. Start with the easy part: the whale shark's spots and the yellow fish.
  2. Save for last: the turquoise water and the hazy sand below. About 66% of the frame has little detail, mostly in the bottom third, and those pieces look alike.
  3. Each tap turns a tile a quarter clockwise; right-click or Shift+Enter turns it back.
  4. Start with tiles that contain a horizon, a body or a straight edge — their upright position is obvious.
  5. For plain tiles, follow the light: water and sky usually get brighter towards the top of the picture.
  6. Few tiles, quick win: try to set each tile with as few taps as possible.

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.
