The standard 52-card pack is used.
Object of the Game
The goal of each player is to win the pot, which contains all the bets that the players have made in any one deal. A player makes a bet in hopes that they have the best hand, or to give the impression that they do.
A single card is dealt face down to each player.
On a signal from the dealer, each player simultaneously lifts their card, placing it on their forehead so that all of the other players can see it, but the player cannot see his own. There is a single round of betting and then a show down.
In some games the suits have rank - Spades (high), Hearts, Diamonds, Clubs - so that the Ace of Spades would be the highest card, the Ace of Hearts the next highest, and so on.
