Kámen – Zbraně – Papír (or Stone – Paper – Weapons) puts you in the shoes of a newly appointed noble in a medieval kingdom that has just welcomed a reformist king. The goal is straightforward: build your castle faster than the other players and keep the border safe. Each game starts with everyone receiving basic resources and then jumping straight into auctions. You bid money for tools, building materials, or military units, using the auction mechanic to decide who gets what. Afterwards, weapon choices follow the classic rock‑paper‑scissors dynamic: each type of equipment beats one and loses to another, creating quick tactical decisions each round.

As the castle rises, you can focus on the economy – buying resources that generate income over time – or pour resources into your army, using weapon cards to defend the frontier against rival nobles. Balancing civil development and military strength is the secret; over‑investing in one side leaves you exposed to the other. The game moves at a brisk pace, with about 45‑minute playtime, and its light complexity (weight 2/5) means even newcomers to auctions can pick it up quickly. Components are sparsely described but clearly illustrated, making rule memorization easy.

With minimal components and straightforward rules, Kámen – Zbraně – Papír is perfect for groups that enjoy light competition, rapid decisions, and a dash of medieval strategy. If you like auction games and want to see rock‑paper‑scissors applied to castle building, this title is a solid pick for your next game night.
