Board games for trivia

There's a lot of discussion about how crossword puzzles and logic games help us stay mentally in shape. But social interaction is important too, and too many brain training games are solitary. I would like to create a board game involving simple puzzles and games, similar to Candy Land except with math facts or trivia questions on the cards. It would be low stress, since the cards would only come up occasionally and other parts of the game would be easy/chance. The wording of the math puzzles could be funny and lighthearted.
