Its 0h h1s companion game!

Remember that little logic game called 0h h1? Well, weve 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.

Its 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

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