So here’s how it’s played: each player puts in an ante (usually one dollar) to play. Using one deck of cards, the dealer deals a card, face down, to each player around the table. The players then place the cards on their foreheads with one hand, so all players except themselves can see what they’re playing with. The card stays held there until the end of the round. If a player looks at their own card, they’re out of the round, and lose their ante.

Next, one-by-one, starting with the dealer, each player puts in their bets or folds. Decisions are based on what a player believes their unseen card is compared to others’ seen cards. Once all bets are in, everyone sees their hand. High card takes the pot.

To continue the game, the next person to the left deals out from the remaining cards—setting aside the cards played in previous rounds. This continues round-after-round until the entire deck is gone.
