The object of the game is to keep your marbles. (AKA – sanity)
It’s a great party game, and a good ice breaker.
You can lose your marbles to the pot or have them stolen. The people I played with had a slightly altered set of rules to SJ Games. We were allowed to get our sanity back and took turns in a clockwise direction. How ever you choose to play, it’s still fun.
SJ Games has a nice demo on how to play the game.
