The players are cowboys who confront each other in a duel, playing their Revolver cards simultaneously. Pure minimalist double guessing in the heart of Far West!

Each player takes the 9 cards of one color. He then discards 2 cards of his choice, face down. The game is played in a series of rounds, each composed of several turns (Duels). At each turn, the players secretly choose one of their cards and place it in front of them, next to the other cards that have been already played.

If the difference between the 2 cards is less or equal to 3, the highest card wins as much Gold as the difference between the cards.

If the difference between the 2 cards is more than 3, the lowest card wins as much Gold as the difference between the cards.

If both cards are equal, there is no winner. 2 Gold are placed between the 2 cards.
