I played "Wits and Wagers" with my extended family last year at Christmas - it was fun!
All of the questions have answers that are a number... everyone writes down what they think the correct answer is... you put all the answers down in order, and then you BET (chips) on which is right! So even if you don't know much, you can still win by figuring out who DOES know
The best part. We had an age range of ~18 to ~60s or so. One question was, "what year did prohibition end?". My lovely 18 year old cousin guessed... something like 1984!
