A gamer is a proactive hobbyist who plays interactive games, especially video games, tabletop role-playing games, and skill-based card games, and who plays for usually long periods of time. Some gamers are competitive, meaning they routinely compete in some games for money, prizes, awards or the mere pleasure of competition and overcoming obstacles. In some countries such as the UK and Australia, the term "gaming" can refer to legalized gambling, which can take both traditional and digital forms, through online gambling. There are many different gamer communities around the world. Since the advent of the Internet, many communities take the form of Internet forums or YouTube or Twitch virtual communities, as well as in-person social clubs. Originally a hobby, it has evolved into a profession for some. In 2021, there were an estimated 3.24 billion gamers across the globe.
