The Game Maker Guild Seal of Approval is given to games that have been rigorously tested from every aspect of design: the mechanics, the graphic design, the rulebook, the theme, and the playability of the game.
In order for a game to receive the Game Makers Guild Seal of Approval the game designer must be a Patron Member of Game Makers Guild and the game must go through four stages of review: Nomination, Intensive Play-testing, Blind Play-testing and Final Play-test and Review by the Curation Committee.
