Oh One 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. Oh One gives you unlimited puzzles for all grid sizes: 5x5, 6x6, 7x7, 8x8

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.
