In 1905, the last great North American gold and silver rush took place near Death Valley, in Nevada. Bullfrog Goldfield is a stock trading game in which players attempt to cash in on the discovery of this ore. Players must develop mines to acquire the ore, construct towns to support the miners, and lay railroads to ship the ore away. Competition can be brutal as railroads race across the desert to arrive at mines first, fortunes ebb and flow on the mercy of mineral veins, and hostile takeovers threaten hard-earned holdings. Only the development of mines brings chance into the game, luck is absent everywhere else.

Bullfrog Goldfield is a "gamers game" encompassing stock purchasing, manipulation and selling; rail and town building; and mine development. These parameters are woven together with a simple, but unforgiving stock market/pay off track. Luck is minimized and shrewd speculation is the name of the game. Expect to add 30 minutes for each additional player over three.
