Tapper, also known as Root Beer Tapper, is a 1983 arcade game released by Bally Midway. The goal of the game is to serve beer and collect empty mugs and tips.
Plenty of thirsty patrons are coming in for a drink. Start tapping the kegs and sliding mugs of root beer down the counter to the thirsty customers. If the customers reach you, or you slide one down an empty counter, you lose a life. Serve them as fast as you can for a high score.
