比赛 (bǐ sài) is the general word for a competition or match, especially in sports. It is different from 游戏 (yóu xì), which means a game or play (often for fun, not necessarily competitive). Also, 竞争 (jìng zhēng) means 'to compete' in a broader sense like business rivalry, while 比赛 focuses on a formal contest with rules.
