Gamer

A "gamer" is someone who plays interactive games, such as video games or tabletop games. Although the term "gamer" may commonly refer to video game players, the term may also be applied to players of other forms of games, such as tabletop games or physical games. Additionally, in some countries such as the United Kingdom, the term "gaming" refers to legalized gambling, which can take both traditional (tabletop) and digital forms (akin to video games), so in these areas gamers may also refer to people who gamble. The term also includes people who work on methods to gamify technologies relevant to gameplay.
