Printable nurikabe
Nurikabe grids in PDF, from 5 × 5 to learn the rule to 7 × 7 for regulars. Nurikabe is a Japanese logic puzzle: some cells carry a number, and you shade the others to separate islands of the stated size in the middle of a single connected sea. Every grid has a single solution, found by deduction; the solutions are on the last pages.
How it works
Pick the difficulty
Easy gives a 5 × 5 grid with small islands, medium a 6 × 6, hard a 7 × 7 with several large islands to place.
Set up the booklet
Choose the number of grids, A4 or Letter paper, and whether solutions are added. Four grids fit on a page, with cells of at least 7 mm.
Print and play
Shade the sea in pencil. Start with cells squeezed between two numbers: they must be sea. A finished island is surrounded by sea on every side.
Printing tips
Choose “Actual size” or “100%” in the print dialog, not “Fit to page”, to keep cells big enough to shade. Black and white is enough: numbers are black and the sea of the solutions is grey. Use a pencil and an eraser: in nurikabe you often go back to a cell. For a class or a club, print the solution pages on a separate sheet and keep it.
Frequently asked questions
What are the rules of nurikabe?
Some cells carry a number: it is the size of the island containing them, and every island holds exactly one number. All the other cells form the sea, which you shade. The sea must stay connected, never form a 2 × 2 block of shaded cells, and two islands never touch along a side.
Does each grid have a single solution?
Yes. Every grid is checked before layout: exactly one solution exists, and it is found by deduction. No guessing needed.
Can I use them in class or in a club?
Yes, freely, including printing them in quantity. Only reselling the files is not allowed.
Are my settings saved?
On your device only, so you get the same difficulty next time. Nothing is sent to a server.
