About the game
In Kingdom of Cards, you’ll take charge of a kingdom entirely made of cards. Players combine and upgrade cards to gather resources, craft tools, and develop their kingdom’s residents—all while fending off relentless enemy attacks. Each card represents a unique resource, item, building, or character, and combining them strategically will unlock even more powerful cards. For instance, combining two “Fabric” cards in a crafting facility creates a “Cloak” card. Pairing that “Cloak” with a “Peasant” card at the Academy could then transform them into a “Thief” card!
Whether you choose to turn your peasants into fearless Mages, Knights, or Vikings, or keep them as essential workers like Miners or Fishermen, the kingdom’s fate lies in your hands. Use your creativity to explore recipes, unlock a variety of resources, and cultivate skilled individuals to expand and strengthen your card kingdom.
The demo offers a sneak peek into the Kingdom of Cards experience with:
- 50 unique cards
- 7 unlockable facilities to craft and enhance your deck
- 5+ areas to explore, conquer, or plunder
- 15+ enemy types to challenge your strategy
- A challenging boss fight that will test your skills
With about 30 minutes of gameplay, the demo provides a thrilling introduction to resource management and card fusion mechanics. If you’re a fan of deck-building strategy games, don’t wait—download the demo on Steam now!
