1UP是电子游戏中，尤其是动作游戏中的一个常见的术语。它是一个表示增加一次游戏机会的符号。在玩家中，通常称为“奖命”或「补只」;「加台」。大陆部分地区称作“加车”。一般玩家在得到一定的分数或者特殊物品时获得的奖励。

1-up (or “1UP”, “1-UP”, etc.), pronounced "one up", is a general term in video gaming that refers to any item which gives the player an extra life, allowing play to continue beyond the game's normal limitation on attempts. Because there is no rule set in place governing all games, the specific implications of 1-ups varies 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.
