Pelicans on the pier posts

Brown pelicans resting on wooden posts above turquoise water

Filling the tank…

In the frame

Five brown pelicans rest on weathered wooden posts above turquoise water, and the one in the middle spreads its wings wide. A blue sky with light clouds fills the top of the picture.

This dive turns the picture into a 5 × 5 slide puzzle: 24 tiles and one empty space. The shuffle is fixed, so everyone starts from the same board, and it is always solvable.

Dive plan

  1. Start with the easy part: the pelicans and the wooden posts.
  2. Save for last: the turquoise sea and the sky. About 33% of the frame has little detail, mostly in the top third, and those pieces look alike.
  3. Finish the top row first, then the left column; the puzzle shrinks to a smaller board each time.
  4. Switch on the numbers if two tiles look alike — they show where each tile belongs.
  5. Look-alike tiles are where the numbers help most: plain water or sand gives few clues about order.
  6. A 5 × 5 board is a real workout; if you get stuck, the hint suggests a move or highlights a misplaced tile.
