Bibinary is a game in which you must find the binary code of numbers. It's almost fun. There is several levels, from A1 to F6. To pass a level, you must find 3 codes. There is two modes : the time mode and the infinite mode. In the time mode, you have a limited time (40s) to find as many binary codes as possible. You can start at the level you want (from the lowest level to the highest already reached level). In the infinite mode, you always start at the lowest level and you must go as far as possible. You win when you pass F6. In both modes, the highest reached level appears on the home page.
