Each Pump It Up dance machine consists of a pad connected to the machine's computer hardware. On the dance pad are 5 buttons: two red ones on the corners closest to the cabinet, two blue ones on the corners farthest from the cabinet, and a yellow one in the middle. On the screen of the machine itself, arrows corresponding to each of these buttons scroll towards the top of the screen, and the player steps on the buttons on the dance pad when the arrow corresponding to the direction on the pad aligns itself with a set of stationary arrows at the top of the screen (sometimes called "targets" or "receptors").
Players receive a judgment for each step based on the accuracy of the step. Judgments include, from best to worst, Perfect, Great, Good, Bad and Miss. The size of these judgments vary from version to version, and sometimes depend on the difficulty of the machine set by the machine operator.
Players generally play until the number of songs they have paid for have been played (usually between 2-5 songs), or the player has failed a song. In some cases, players may "fail" a song and cause their play to end early, and in others, players may earn a bonus song for exemplary performance on songs played previously during the round. Also, the machine operator may turn on a function known as "Stage Break", causing play to stop immediately once a player's lifebar is depleted. If Stage Break is off, players only fail the song (and cause play to stop) by getting a combo of 51 consecutive misses.
