CastleUp is a competitive card game for 2-4 players set in the lively Middle Ages. Each player builds and expands their own city, competing for dominance through strategic choices and clever planning. The game mixes medium-complexity strategy with deck and tableau building mechanics. Every card you play is a key decision, adding depth as you grow your city. Unique mechanics, like cards that flip when damaged while staying visible to everyone, create tactical layers. Resource management is crucial, requiring smart use of assets to outsmart your opponents. Designed for players who prefer skill over luck. With each turn building on the last, your actions drive towards victory in a multi-round game. The winner is the one with the most victory points when the deck runs out.
