    • Well-thought
    • Can become repetitive

    "Brain Teaser"


    Oh h1 is a logic puzzle game where the only thing you need to do is to complete the grid.

    You must keep in mind that you can't have three red and blue tiles next to each other and that a full line must have as many red tiles as blue ones but be different at the same time.

    With those restrictions, try to figure out how to solve each puzzle!


    The idea behind the game is actually innovative and challenging and the gameplay couldn't be simpler: just tap a tile to change it to red or blue.

    If you want to make the game more difficult, try changing the grid size.


    Can become repetitive after playing for a while.

    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.
    0h h1 is a little gift to you. We hope you enjoy it.
    0h h1 can also be played on
