A playtest is the process by which a game designer tests a new game for bugs and design flaws before releasing it to market. Playtests can be run "open", "closed", "beta", or otherwise, and are very common with board games, collectible card games, puzzle hunts, role-playing games, and video games, for which they have become an established part of the quality control process. An individual involved in testing a game is referred to as a playtester.
