1-up (also known as 1UP, 1-UP, XUP; pronounced “one-up”) is a video game term that succeeds the player-character’s gained extra life, allowing continuous play before game over. Because there are no universal game rules, specific 1-ups vary tremendously from game to game. However, they are very often rare and difficult items to acquire, occasionally requiring the player to demonstrate significant skill or risk an unnecessary death.
In certain games, it is possible to receive multiple extra lives at once. When this happens, the number of extra lives obtained sometimes changes the notification from “1UP” to a variant that reflects the total lives earned: two lives would be “2UP”, five lives would be “5UP”, and so on. Games that don’t follow this rule often simply repeat the “1-up” notification in rapid succession concurrent with the number of lives awarded.
