You are the leader of a new Kingdom, starting from nothing and hoping to reach the highest levels of Prosperity. Each turn, play Cards to add Citizens, Constructions, Animals, and Soldiers to your Kingdom, building a city that can produce vast amounts of resources and protect itself from disease, invaders, and other challenges.

Card Kingdom is all about trying to create synergies, placing Citizens near each other to generate resources and activate abilities. As your city grows, you will need to rearrange things and decide what must be kept, and what must be removed to make way for new additions. Do you keep your Cobbler near the Farmers to increase your Food, or is it time to shift it over to boosting the Miners for Labor? Or perhaps we could remove the Cobbler and put in a Cook instead?

Challenges will emerge from nature, hostile nations, and the fabric of magic itself. While you are trying to grow your Kingdom, you must also find ways to protect it from disease, criminals, invaders, and more. New challenges are always emerging, and always growing stronger— so your Kingdom must always be growing stronger as well.

Most of your resources reset every turn. This means that if you can't afford to build a Construction you want, you can't just sit around and wait— you need to figure out what must change in your Kingdom to reach the levels of resources required. Reach new levels of production by carefully arranging Citizens to activate synergies.

As you ascend through the Tiers of Prosperity, you will be continually unlocking new Cards to add to your Kingdom, discovering new resources, abilities, and synergies. Will the older Citizens be valuable building blocks to combine with your newer members, or should some of them be removed to make way for new abilities?
