Professor Pac-Man/Gameplay

In Professor Pac-Man, players must answer multiple-choice questions by using the buttons on the control panel. Unusually for an arcade game, the first player's buttons are on the right side of the panel, while the second player's are on the left side. In a 1-player game, the Professor challenges the player to answer his questions correctly and quickly in order to get the highest score. The player is given two chances to answer each question - but if he answers incorrectly on the first time, he loses a life. If time still remains on the question, he can try to answer it again - however, if the time runs out before he has the chance to do so, he will not lose another life. But if he does have enough time to try and answer again and is still incorrect, he will lose another life. The player can use this to his advantage by not trying to answer a question the second time if he is not 100% sure of the answer, as he will not lose a life if he doesn't try - but he will lose a life for a second attempt which turns out to be incorrect.
