In the frame
Dozens of purple sea urchins cover a rocky seabed between tufts of red algae, and an orange sea star lies in the middle. Kelp stalks rise into teal water in the background.
This dive leaves all 12 tiles of a 4 × 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 orange sea star and the purple urchins around it.
- Almost every part of this frame has detail. The least distinct part is the teal water between the kelp stalks, and even that has texture to go on.
- 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.
- Lines run through most tiles here, so check that each one continues smoothly into its neighbours.
- Work row by row so you never lose track of which tiles are done.

How deep it goes
Depth 1 of 5 — a calm paddle.
Reef dives sit in the middle: enough pieces to need a plan, never so many that a phone screen feels crowded.
