Using your mathematical knowledge, keep your airplane flying in an enjoyable autogenerated cartoon world with bright and happy music in the background. With four game modes, three types of questions, two number sets, and an extra difficulty layer. Recommended especially for children or kids and for people that just want to make quick small mathematical calculations to improve their mental skills with cheerful music. The game comes with eight different languages and video ads only appear when you finish your game session. The four game modes are: - Keep flying!: The plane is falling and answering correctly is the only thing that helps your plane to go up. If you touch the ground the game ends! - No worries: In this game mode you just need to answer with no worries. (Relax mode :P) - Do not fail!: Similar to the previous one but you have an error limit. - Time flies!: Time is running out, but answering correctly gives you more time. * 'Use keypad' special option: This let you switch between an answer selection mode and a keypad to input your answers. To those that want to train their brains in a different way. The included languages are: - English - Spanish - Portuguese - French - German - Russian - Hindi - Chinese simplified The game comes with two worlds: - Central Europe (well, more or less...) - Winterland (is an easter-egg!, try to find it!) * More worlds are planned ;-)
