Printable 7x7 Nurikabe Puzzles (Medium), Pack 2

The everyday size: a 7x7 grid leaves room for real chains of deduction without taking over your afternoon. Good for regular solvers and older students.

Pack 2 of 3 has six Nurikabe puzzles with an answer key on the second page. Each grid has 6 to 8 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.
