    Nice game! I love the concept

  • nick

    hey this is incredibly addicting, but the colors are actually really distracting.
    if you could figure out a specific color for each number, it would make combing through the different colors a lot easier, especially when it gets to higher difficulties where i had more trouble finding the numbers i wanted than with the actual math.

    • hyperandroid

      Hi there,
      you’re right, color numbers are disturbing, and so the intention was ;).
      But you’re right, and i’ll be adding different colors for the same number as you progress throughout the game, or just do color changing for a ‘hardcore’ difficulty level.
      Thanks for the tip.

    very, very nice !

    very addictive…how can i pause the game? thanks

    • hyperandroid

      I’m about to publish a more polished version of the game.
      There’ll be no pause, but you’ll be able to rest between game levels.

    This game is the prettiest canvas/js game I’ve played. Excellent work.

  • Jeroen Visser

    It looks like a flash game! And, Then you look at the source, and you see it’s awsomeness underneath :) The grafics are AWESOME! And the concept is cool. This is an excelent example of what you can do with JS canvas!

    How  can download this game?

    • Anonymous

      I’m sorry tonys, but you must not download the game locally. Instead, play it online.
      The game is copyrighted but the source code is published for learning purposes.

  • Mark Knol

    The help button freezes the full game.. ?!

    • Anonymous

      Should not.
      Could you point me out where exactly that happens ?

  • Faldrian

    Can you please post a description of WHAT TO DO in this game here?
    I just don’t get it. And the Help-Button (and die ?-Button freeze the game in Firefox and Chrome). Maybe there is some image not found or something other, that causes JS to stop running?

      thanks for spotting. You were right some resources had been moved elsewhere sorry for that.
      The game should be working properly again.
      Thanks again.

    Hello, sir. Am I allowed to modify the source code of this game? I want to make a different mathematical game, and I want to make it look like this. It will not be released commercially, just for pure educational use. I’m anticipating for your favorable response. Thank you. :)

      Hi Jared,
