About 0h h1

0h h1 is a little logic game that follows three simple rules:

- Three red tiles or three blue tiles next to each other in a row or column isn't allowed
- A full row or column must have as many blue tiles as it has red ones.
- No two rows are the same. No two columns either.

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 h1 gives you unlimited puzzles in four grid sizes:

4 x 4
6 x 6
8 x 8
10 x 10

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 h1 is akin to Binary Sudoku, also known as Takuzu, Binairo or Binaire.
