In the frame
A green sea turtle glides left to right over the edge of a coral reef, its patterned shell and flippers in sharp detail. The reef fills the lower left; the rest is open, deep blue water.
This dive leaves all 15 tiles of a 5 × 3 board in place but rotates them by 90, 180 or 270 degrees. Tap each tile until the whole picture stands upright.
Dive plan
- Start with the easy part: the turtle's patterned shell and flippers.
- Save for last: the open blue water. About 53% of the frame has little detail, mostly in the top third, and those pieces look alike.
- Each tap turns a tile a quarter clockwise; right-click or Shift+Enter turns it back.
- Start with tiles that contain a horizon, a body or a straight edge — their upright position is obvious.
- For plain tiles, follow the light: water and sky usually get brighter towards the top of the picture.
- Plain tiles can look right at two angles; check the direction of the light and the texture.

How deep it goes
Depth 4 of 5 — a demanding dive.
Wall dives drop off into bigger boards, where the plain parts of a picture start to slow you down.
