Since 1990, each year, American Mensa selects several (usually 5) games to recommend through its Mind Games competition. These games are named Mensa Select. The GeekList called Mensa Select winners 1990-2019 by BGG rating contains a list of Mensa Select winners sorted by BoardGameGeek rating.
From 1990-1995, the Mind Games judges were selected by the American Mensa national office. Since 1996, all members of American Mensa have been eligible to attend Mind Games as judges, although a registration fee is required.
