PitBulls

Stock exchange simulation game, where the TRADERS watch a 10-round, 8-way contest (among 8 COLORS) and BET/TRADE on the winner of that contest.

The themes are negotiation, probability estimation, and trend-spotting. The goal is to finish with more money than you start with, and even better — finishing with the most money. The mechanism of negotiation is "open outcry" — there are no "turns"; it's everyone's turn at all times to make any deal they can with anyone who is willing to listen to their price(s).

All TRADERS start with a portfolio of 16 shares of random COLORS, plus $200 in cash. As the contest proceeds through 10 rounds, a TRADER use his/her cash to buy COLORS from other TRADERS, and the TRADER will sell shares of his COLORs to raise cash.

The game ends when the 10-round contest is over. At that time the shares of the winning COLOR are worth $100, and the shares of all other COLORs are worth zero. Each TRADER finishes with a total value of his/her portfolio: CASH + SHARES FINISHING "in the money".
