the controls consist of a four-position joystick and a tap handle. the game screen features four bars, each with a keg at one end and a door at the other. customers enter through the doors and slowly advance toward the kegs, demanding service. the player controls a bartender who must pour drinks and slide them down the bar for the customers to catch. pushing the joystick up or down instantly moves the bartender to the keg at the next bar in the chosen direction, with the top and bottom of the screen wrapping around to one another, while pushing left or right causes him to run along the bar where he is stationed. when the tap handle is pulled down, the bartender instantly moves to the keg (if he is not already standing there) and fills a mug; releasing it causes him to slide the mug along the bar.
