O Grande Imperador is a simple card game for 3 to 5 players. In it, players dispute the favour of the emperor by building walls. These walls are built by putting the cards in sequence from 1 to 10, and each player has 10 stock cards and 5 hand cards. A player can use any of his hand cards or the top stock card to put in a wall. The objective is to use all of your stock cards. Hand cards are replinished each round.
