The porpuse of the game is to find the result of the addition. You have 60 seconds (GameTime), 3 lifes and 6 possible solutions. For every question you have 10 seconds (AnswerTime). If you choose a wrong solution, than you lose one live and the answer time starts again from 10 seconds. If you choose 5 correct solutions in a row, than you activate the Bonus Round. This means that the GameTime pauses and just the AnswerTime is running. This bonus round lasts 10 seconds. In case of wrong answer you will not lose any live. The game ends when you lose all your lives or the game time expires. Have fun :)
