"Sangoku!" is a card game for two people in which the players become monarchs of one country, led by warlords, aiming at unification of the three countries, set in the world of the Chinese Three Kingdoms period. Each player draws cards from the deck alternately one card at a time and place cards in his hand next to one of the 5 castle cards placed in the field. You can declare "Siege" by arranging 5 cards next to the castle. You can earn a castle if your opponent does not have five cards at his next turn in the siege declaration. However, in case he managed to place five cards in his side of the castle sieged, a decisive battle will be held to win the castle by the stronger combination of cards. A player who wins 3 castles first wins the game.
