Card Wars is a card game that Finn and Jake play in the episode "Card Wars". The rules to the game are "super complicated," and it took Jake two hours to explain the basics of them to Finn. It has also been made into an app, the wiki for which can be found here. There is a real-life version of Card Wars as well.

In "Wake Up", the Cosmic Owl and Prismo are seen playing Card Wars when Finn and Jake enter the Time Room.

In "Daddy-Daughter Card Wars", Charlie, Grand Prix, and Moniker also play the game.

In the Distant Lands special entitled "BMO", Y5 and Mr. M are seen playing a holographic version of Card Wars.

Known rules[]

When the game starts, two players get approximately 10-20 cards. There are two stages to a turn: a floop stage and a battle stage. A player may take any building card and floop it (turn it to the left) to appear as holograms on the board. Buildings have special effects which can aid the player using them. There are only two known elements of the game, which are corn and learning. Corn cards happen to be powered by corn fields, which are given to the player at the start of the game. Learning cards are powered by intelligence, so a player could send someone to learn, and in turn, that person will receive power.

A player's land is divided into 4 parts, some of those lands being corn, wheat, blue, crystal, lizard, and burning. A player may select a creature and either activate it (turn it to the right) to make it attack one or more of the other player's creatures, or floop it to make it use its special ability. Also, at the lower right corner of each creature card there are two numbers with a forward slash representing that specific card's stats. A player can also use activation to make a creature learn. Before beginning a turn, a player must discard a card from their hand and pick up another card from their deck. The player that loses all of their creatures and their buildings at the end of their turn first loses the game.

In "Daddy-Daughter Card Wars", Jake explains the games as

the king and queen of tabletop games. It combines the mechanics of simulated combat, hand management, commodity speculation, worker placement, blind auctioning and set collection. Battle happens in one of four combat lanes each deriving its power from one of the 16 themed-elements: corn, wheat, blue, crystals, acumen, torpor, frozen lakes, lizard holes, learning…

    • Ancient Scholar: 3/4

    • Wandering Bald Man: 1/1
