If you're already a master of the cattle routes in Great Western Trail, get ready to add another piece to your strategic puzzle! The '13th Building Tile' isn't a full-blown expansion, but rather a promotional item that introduces a new layer of possibilities to your construction planning. It acts as an 'upgrade' to your private building board, offering two distinct paths (sides A and B) for you to choose from depending on your current game needs.

On side A, the focus is on territorial expansion and infrastructure. You discard exactly one gray cattle card (the 'Jersey') to perform a single auxiliary action and place one of your private buildings onto a building space on the trail. It's a fantastic move for players looking to solidify their presence on the map, but keep an eye on your wallet: for every craftsman required by that building tile, you must pay 1 dollar. It's a classic 'pay to grow' mechanic.

On side B, the game shifts slightly toward capital accumulation and agility. Here, the financial reward takes center stage: you gain twice as many dollars as you have discs on train stations. To top it off, you get to perform either one or two auxiliary actions. This is the ideal choice for those moments when you need a quick cash injection or an extra move to fine-tune your end-game strategy.

Just a reminder: this is a supplement, meaning you'll definitely need the base game to make use of it. The set comes with four identical tiles, one in each player color, ensuring everyone at the table gets a shot at using this new resource management and construction tool. It's a small addition that can make a massive difference in your final score!
