They gathered for the group's annual Mind Games event to learn, play and rate five winning new board games, The San Diego Union-Tribune reported Sunday.
Each of the 240 Mensa members from around the United States had to play at least 30 games and then submit a ballot of their favorites.
"This is going to sound pathetic, but this is the highlight of my year," said John Hornberger, 44, of Albany, N.Y.
Hornberger said he has been attending the event for about 10 years and is the proud owner of 1,028 games.
In the very competitive board game market, a Mensa Select Seal carries weight with game shops, hard-core gamers, and even moms -- a segment heavily courted by toy and game companies, the Union-Tribune said.
"For anyone who is into logic and strategy games, they want to see the Mensa award," said Monica Lucas of game publisher Mind Twister USA.
