    A fascinating and challenging puzzle for smart minds

    • Excellent, simple design of UI
    • Actually challenging
    • 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 a little gift to you. We hope you enjoy it.
    0h h1 can also be played on

    And don't forget to check out its sibling game 0h n0!

    When you find yourself somewhere, having to wait unexpectedly, this game (and it's companion) are awesome to have. It only takes a little while to complete one of the games so you have something to do other than complain about waiting somewhere unexpectedly. :)) I also like that there isn't any background music and NO ads! It does require a few brain cells..and that is okay.
