Crystal Faire (2006)

In a round, the first player makes two offers of four to six marbles to the other players. Each of the other players make a counter offer. The first player then picks one of the counter offers, and the person whose offer they picked then chooses one of the first bidders offers. They then exchange marbles. This leads to a round where the amounts that each color is worth. Whomever bids the highest wins the amount of cash that the color is worth. The person with the highest amount of cash at the end of the game is the winner.
