Printable 5x5 Nurikabe Puzzles (Easy)

The smallest Nurikabe puzzles we print. A 5x5 grid is the right place to learn the rules, and it suits younger solvers, a classroom warm-up or a quick coffee break.

This first pack has eight Nurikabe puzzles with an answer key on the second page. Each grid has 3 to 4 numbered islands.

How to solve

  • Island sizes: Each number is part of a white island with exactly that many cells.
  • One number per island: Every island holds exactly one number, and islands never touch along an edge.
  • One sea: All shaded cells connect into a single group.
  • No pools: No 2x2 square may be fully shaded.

Free to print and copy for home, classroom and library use. Every puzzle has one answer you can reach by logic alone.
