The central board has a map with the goods available for delivery. You have a personal play sheet with the same map, on which you draw your rail network and keep track of your engine fleet. When you make a delivery, the goods are removed from the central board and you earn points for cities and towns crossed. Once three cities on the central board have been emptied from available goods, the game ends. You then collect points for your deliveries, your engines, your network, and a few bonuses.
SteamRollers is a fast and fun roll and write game. The active player rolls all the dice, then in turn each player picks a dice and uses it to either draw rail, improve his engine, do research, or make a delivery. Once each player has picked and used a dice, the next players rolls the all dice and so on.
