18CO: Rock & Stock

18CO: Rock & Stock is an 18xx game where three to six players compete to earn money and build the best stock portfolio by investing in and operating railroad Corporations within the state of Colorado. Corporations race to complete a route from the East to Salt Lake City. New Corporations form and take control of old, failing Corporations. The player with the most cash and stock value when the bank runs out of money wins the game.

Highlights Moving Bid Auction allows players the option of escalating their already placed bid to a higher value private. Incremental Capitalization in varied Par Zones based on 3 Corporation Classifications. Corporations can buy and sell shares of other Corporations, as well as itself. Corporations owning the Presidency of another Corporation perform a Takeover. Presidents can buy shares from their Corporations. Tile lay prevents a third-party Corporation from accessing play track. Some Green towns may be upgraded to Brown cities, which may help or hurt. A bonus jump based on revenue pushes a stock price up, not further right. Failing corporations are actioned for Takeover by other Corporations.

Gameplay Notes There is a lot of cash flowing in this game, unlike 1830-based games. Not all corporations are created equal, intentionally. Corporations owning shares open up a lot of gameplay possibilities that can be missed if you ignore them. Players often forget the tile lay rule for upgrading plain track tiles from yellow to green/green to brown. Utilize the unique track lay rules to keep opponents from using important track, such as a route to Salt Lake City. Be careful on competing for a route you won't be able to access. Consider investing in corporations likely to complete such routes.
