Puzzles Like Hitori: Other Japanese Shading Puzzles to Try

If Hitori has won you over, here is some good news: it belongs to a whole family of logic puzzles built on the same satisfying idea of shading cells to solve a grid. Once you enjoy deciding which cells to black out, a dozen other puzzles open up, each with its own clever twist on the black-and-white mechanic. This guide rounds up the best puzzles like Hitori, from its closest cousins to fresh challenges that will feel familiar yet new. When today's grid is done, you will always have somewhere to go next. First, though, you can play a Hitori puzzle any time.

What makes a puzzle "like Hitori"?

Hitori is a shading puzzle: instead of filling cells with numbers, you blacken some cells and leave others white, following logic rules. That puts it in a rich genre of mostly Japanese logic puzzles where the answer is a pattern of black and white cells rather than a grid of digits. The puzzles below share that DNA, and several share Hitori's two signature rules too: black cells that can't touch, and white cells that must stay connected. If those constraints are what you love about Hitori, these are your natural next stops.

Nurikabe: shade the sea around islands

Nurikabe is Hitori's closest relative in spirit. You shade cells to create a connected "sea" of black that flows around numbered "islands" of white, where each number tells you how big its island is. The sea must be fully connected and contain no solid 2×2 block, and the islands must stay separate. If Hitori's connectivity rule (keeping white cells joined) is the part you find most interesting, Nurikabe takes that idea and makes it the whole puzzle. It is a brilliant next step.

Kuromasu: shade with a counting twist

Kuromasu (also called Kurodoko) is almost a mirror image of Hitori. You shade cells under the same two structural rules Hitori uses, black cells can't touch and white cells stay connected, but the clues work differently: a numbered white cell tells you how many white cells are visible from it in a straight line, up, down, left, and right. It is uncanny how familiar Kuromasu feels to a Hitori solver, right down to the shading instinct, with just a new kind of clue to learn.

Binairo: black and white, two symbols

Binairo (also known as Takuzu or the binary puzzle) trades numbers for a pure two-state grid of 0s and 1s, which you can think of as black and white. You fill every cell so each row and column has an equal split, never three of the same in a row, and no two lines identical. It is less about elimination than Hitori, but if what you enjoy is the clean black-and-white, this-or-that logic, Binairo delivers it in its most distilled form.

Nonogram: 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 when you solve it correctly, the shaded cells form a picture. The deduction is different from Hitori, 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.

Star Battle and Aquarium: place and flood

A couple more on-site puzzles scratch the shading itch from new angles. Star Battle has you place stars so that none touch, with exactly the right number per row, column, and region, which trains the same "where can this go without crowding its neighbours" thinking Hitori rewards. Aquarium asks you to flood regions with water to given levels, a fill-the-cells puzzle with a satisfyingly different logic. Both are a refreshing change of pace once Hitori feels comfortable.

Why the shading family is worth exploring

The lovely thing about shading puzzles is how transferable the instinct is. The judgement you build in Hitori, weighing which cell to black out without breaking adjacency or connectivity, carries straight into Nurikabe and Kuromasu, and 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 duplicate for the day and want more, you now know where to look. Start with the original that brought you here: play a Hitori puzzle now, or learn the rules first.

Frequently asked questions

What puzzles are like Hitori?

The puzzles most like Hitori are other Japanese shading puzzles. Nurikabe and Kuromasu are the closest, sharing Hitori's "black cells can't touch, white cells stay connected" rules. Binairo offers pure black-and-white logic, while Nonograms let you shade cells to reveal a picture. Star Battle and Aquarium add related place-and-shade challenges.

What is a shading puzzle?

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

What should I play after Hitori?

If you enjoy Hitori's connectivity rule, try Nurikabe, which builds a whole puzzle around connected shading. Kuromasu is the closest cousin, using the same structural rules with counting clues. For pure black-and-white logic, try Binairo, and for a visual twist, try Nonograms.

Is Nurikabe like Hitori?

Yes, Nurikabe is one of the puzzles most like Hitori. Both are Nikoli shading puzzles where you blacken cells under the rules that black cells can't touch and white cells must stay connected. Nurikabe adds numbered islands whose sizes you must match, making connectivity the central challenge.
