The classic gameplay is based on hitting lit targets and clearing banks. You score big points by building up to the maximum bonus. Normally, your bonus progression is reset between balls. By clearing all ten drop-targets up top with one ball, your bonus progression is not reset when you lose a ball. You add to your bonus by hitting the lit target up top, down below, or advance two by rolling over the lit monkey. Each time you hit the targets, the lit targets and the monkey move.
