To commit the cards, remove them from your hand and hold them in front of you, so that you are the only one who can see the faces of the cards, but all players can see how many cards you have committed. All other players but the defender are also required to commit as many cards as they have Royals in play. The defender may commit a quantity of cards up to the number of Royals the defender has in play. Once all these cards are committed, the defender asks all players to drop their committed cards, face up on the table. The defender then pairs attack cards and block cards as the defender sees fit.
Face cards have no value during an attack.
A block card will successfully cancel an attack card if the block card's value is equal to or greater than the attack card's value. After an attack, the defender decides how to distribute all successful hits among the defending Royals. You may only attempt an assassination against a player with one or more Royals in play, but to make the attempt, you do not have to have any Royals in play yourself. You may not attempt to assassinate your own Royals. The owner of the Royal must commit one card.
