The player serves customers by filling a mug at one of the four taps. Once the mug is full, the player releases the tap which automatically slides the mug towards the advancing customer. Customers catch mugs that are slid towards them, as long as they are not already drinking a beer, or otherwise distracted. If a mug is not caught by a customer (whether the customer is already drinking or distracted, or if there is no customer), then it falls off the bar on the other end, resulting in a loss of a life for the player. If a customer does catch the mug, though, then he or she is pushed back some amount towards the opposite end of the screen. The goal is to push the customer completely off the screen, but if they are not then they will stay and consume their drink in place.
