Platform game, or platformer, is a video game genre characterized by jumping to and from suspended platforms or over obstacles. It must be possible to control these jumps and to fall from platforms or miss jumps. The most common unifying element to these games is a jump button; other jump mechanics include swinging from extendable arms, as in Ristar or Bionic Commando, or bouncing from springboards or trampolines, as in Alpha Waves. Games where jumping is automated completely, such as The Legend of Zelda: Ocarina of Time, fall outside of the genre.

作为平台游戏，必须能够让玩家操纵角色的跳跃，让其从一个平台跳到另一个平台，或者没跳过去而掉下来。
