From the rules: "When the playing cards go away for the night, everything seems calm. But really, inside the pack, the cards are battling it out to see who will be the Ruler of Decktonia! Will it be the Blacks or the Reds? Each night the wars rage on, and the kingdoms change from one to the other. Who will it be this time?" A simple card game where players use a regular deck of playing cards to see who can have the largest standing army by the end of the game. Each turn the player can lay a card to build his or her army, and use a royalty card that has various effects such as taking away an opponent's army, drawing cards, or protecting one of their own armies from the enemy. Perfect as a filler between larger games, or fun on its own - this game is easy to learn, and since it uses just a regular pack of playing cards, can be played anywhere.
