Description

It's 0h h1's companion game!

Remember that little logic game called 0h h1? Well, we've made a challenging new puzzle game to go along with it! Meet its companion... 0h n0.

0h n0 is a lovely little logic game that follows its own three rules:

- Blue dots can see others in their own row and column.
- Their numbers tell how many.
- Red dots block their view.

It's up to you to complete the grid without ever having to guess. Simply tap a tile to make it blue or red and complete the grid. 0h n0 gives you unlimited puzzles for all four grid sizes:

5 x 5
6 x 6
7 x 7
8 x 8

And now included: 4 x 4 and 9 x 9 boards!

Each puzzle can be played in perfect Zen mode without any pressure. But you can attempt to beat your personal best time in the game's time trials, unlock fun achievements and compete with friends in leaderboards.

0h n0 is free, without ads, without social network requirements, without locked features and without nag screens. 0h n0 is a little gift to you. We hope you enjoy it.

0h n0 can also be played on 0hn0.com.
And if you haven't played its sibling yet, go visit 0hh1.com.

Papa mison ,

Great game

Similar to “oh hi” in that it requires some basic pattern recognition, and quick thinking. Better than “oh hi” because it’s a bit more complex and requires some math skills. Great way to wake up your brain when competing against the clock.

Love it

Almost as good as oh hi. One thing: I wish I could mark numbers that I’ve satisfied and no longer have to figure out, or that they’d be grayed automatically. (I’d rather mark them myself.)

Addicting game, but one suggestion

Great game. One suggestion: allow swiping to turn tiles blue. I would be able to solve puzzles even faster!!!
