How to play: First, each player starts as a producer of key commodities. Decide which commodities to produce based on the market demand. You can either use the produced commodities to build towns or sell them to get profits. With these profits, you can participate in auctions for railroads or buy powerful buildings. Keep an eye on the changing market to adjust your strategy. Attention: Make sure to read the rules carefully before starting the game. This will help you understand how to produce, sell, and use profits. Also, since it's a game for multiple players, respect other players' decisions and turns. Maintenance: Keep the game components in a dry and clean place. If there are any cards or pieces that get dirty, you can gently wipe them with a soft cloth. Avoid bending or tearing the game cards to ensure they can be used for a long time.
