Nurikabe Solver

Eric Holzer and I have written a Nurikabe Solver and a GUI for our high school graduation project (Travail de Maturité, or TM). The algorithm has been originally written in Python, and a JavaScript version has been implemented below. All grids have been taken from puzzle-nurikabe.com.

Choose a Nurikabe grid to solve:

Hover for Nurikabe rules
  • Each number on the grid represents an "island" size
  • The number of tiles of an island must be equal to its size
  • The islands can only touch diagonally
  • The space between islands is called "wall"
  • The wall must be continuous
  • The wall can not contain 2×2 blocks
