In Steam Power players "race" to build the best rail network to meet their contractual obligations and make the most money.

On your turn you can perform two actions from a selection of choices letting you lay tracks build factories fulfill contracts earn money or collect more contracts. Building a factory brings resources to the board that all players have access to...at a price.

The game ends when a certain number of contracts are fulfilled which varies by player count. The player with the most points (and money which converts to points) wins.
