OhnO Puzzle 2017 app for iPhone and iPad

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

OhnO 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. OhnO gives you unlimited puzzles for all grid sizes:

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

And newly added: 4 x 4 and 9 x 9!

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.

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