Abstract
A pinball game is provided with a control system which enables a game player to choose between a novice mode of play and a normal mode of play. In novice mode, game play proceeds for a predetermined time, regardless of the number of game balls played and selected game features, such as the tilt sensor, may be disabled. Game bonuses and free games may be made unavailable in novice mode to encourage experienced players to play in normal mode.
