Puzzles Like Nurikabe: Japanese Shading & Island Puzzles

If Nurikabe has hooked you, here is the good news: it belongs to a whole family of logic puzzles built on the same satisfying idea of shading cells to shape a grid. Once you enjoy deciding which cells are black and which are white, a long list of other puzzles opens up, from near-identical cousins to fresh challenges that feel familiar yet new. This guide rounds up the best puzzles like Nurikabe, including its closest Japanese relatives and the on-site puzzles you can jump to next. When today's islands are built, you will always have somewhere to go. First, you can play a Nurikabe puzzle any time.

What makes a puzzle "like Nurikabe"?

Nurikabe is a shading puzzle: instead of writing numbers, you blacken some cells and leave others white, following logic rules, and the answer is a pattern of black and white. It is also a region puzzle, because you are shaping connected groups of cells (a sea and a set of islands). That puts it in a rich genre of mostly Japanese logic puzzles where the goal is to carve a grid into the right black-and-white shapes. The puzzles below share that DNA, and several share Nurikabe's signature rules too: a connected region, no 2×2 pools, and pieces of a fixed size.

Hitori: shade out the duplicates

Hitori is Nurikabe's closest on-site relative. It is another Nikoli shading puzzle where you blacken cells and keep the rest connected, but instead of building islands you start with a full grid of numbers and shade out the duplicates so none repeats in a row or column. The connectivity instinct you build in Nurikabe carries straight over, just applied to the white cells instead of the black sea. Our Nurikabe vs Hitori comparison digs into the differences, but if you want one puzzle to try next, this is it.

Nuribou and Mochikoro: the Nurikabe family

Nurikabe sits at the head of a small family of related Japanese shading puzzles that tweak its rules. Nuribou ("paint the stick") replaces islands with straight "walls" or strips of a given length, while the black region must avoid 2×2 pools just like Nurikabe. Mochikoro and Mochinyoro are close variants that adjust how the white regions and the black connectivity work. These are harder to find than mainstream puzzles, but if you adore Nurikabe specifically, they are the puzzles that feel most like coming home. They show just how much depth the basic "shade a connected region around sized pieces" idea can hold.

Nonograms: shade to reveal a picture

Nonograms, also called Picross or Griddlers, are the most visual shading puzzle of all. Number clues along each row and column tell you which cells to shade, and a correctly solved grid reveals a picture. The deduction is different from Nurikabe, with clues running along lines rather than describing islands, but the core action, deciding cell by cell what is black and what is white, is the same satisfying motion, with a rewarding image at the end.

Binairo, Star Battle and Aquarium: more black-and-white logic

A few more on-site puzzles scratch the shading itch from new angles:

• Binairo (also called Takuzu) is pure two-state logic: fill a grid with 0s and 1s, which you can think of as black and white, so each line is balanced and no three identical cells sit in a row. It is the most distilled form of black-and-white reasoning.
• Star Battle has you place stars so none touch, with the right number per row, column, and region. It trains the same "where can this go without crowding its neighbours" thinking that Nurikabe's island isolation rewards.
• Aquarium asks you to flood regions with water to given levels, a fill-the-cells puzzle with a satisfyingly different logic and a strong sense of shaping regions.

Why the shading family is worth exploring

The lovely thing about shading puzzles is how transferable the instinct is. The judgement you build in Nurikabe, shading a connected region without creating forbidden shapes or cutting things apart, carries straight into Hitori, Nuribou, and the wider family, while the broader black-and-white thinking helps with Binairo and Nonograms. Each puzzle feels fresh because the rules change, yet familiar because the basic action is the same. That blend of novelty and comfort is exactly why fans of one shading puzzle tend to fall for the whole genre.

So when you have shaded your last sea for the day and want more, you now know where to look. Start with the island puzzle that brought you here: play a Nurikabe puzzle now, or learn the rules first.

Frequently asked questions

What puzzles are like Nurikabe?

The puzzles most like Nurikabe are other Japanese shading and region puzzles. Hitori is the closest on-site relative (another Nikoli shading puzzle with a connectivity rule), and Nuribou and Mochikoro are direct cousins in the Nurikabe family. Nonograms, Binairo, Star Battle, and Aquarium offer related black-and-white or region-shaping logic.

What is a shading puzzle?

A shading puzzle is a logic puzzle you solve by blacking out some cells and leaving others white, following rules, rather than filling cells with numbers. Nurikabe, Hitori, Nuribou, and Nonograms are all shading puzzles. The solution is a pattern of black and white cells.

What should I play after Nurikabe?

Hitori is the most natural next step, since it is another Nikoli shading puzzle that rewards the same connectivity instinct. If you want the closest possible match, seek out Nuribou or Mochikoro, the direct Nurikabe variants. For a more visual change of pace, try Nonograms, and for pure two-state logic, try Binairo.

What is Nuribou?

Nuribou ("paint the stick") is a Japanese shading puzzle in the Nurikabe family. Instead of islands of a given size, the white clues form straight strips or "sticks" of a given length, while the black region must stay connected and avoid 2×2 pools, just like Nurikabe. It is one of several variants that build on the Nurikabe idea.
