This is a great game, combines betting with knowledge and some strategy.

Really interesting and addictive.

Questions like “What was the shortest term of a US President” in days. You write your answer in secret then place them on a scale, lowest to highest. Those are then worth 2/1, 3/1, 4/1, 5/1. You bet on your answer or another player’s, and of you’re right you get that wager back.
