Earlier this week at the Mensa Mind Games in Herndon, Virginia, 300 judges played for 48 hours to choose these 5 games from among 68 as the 2012 Mensa Select winners:

IOTA—A card game, in which to play and score cards, each of the three attributes for all cards in a line must either be all the same or all different.

Snake Oil—A party game of making up crazy products and convincing people to buy them.

Mine Shift—Navigate your jewel through the maze mine, or rearrange the mine.

Coerceo—In which the players attempt to surround each other’s pieces to capture them and also the board shrinks as the game is played.

Tetris Link—Drop Tetris pieces in to the tower slot. Linking pieces with the same color earns points but leaving gaps earns a penalty.
