Rules for the no-peekie version:
Each player is dealt a hand of seven cards, all face down. Players may NOT look at these cards! Starting from the dealer's left, each player bets then turns over one card at a time until (s)he has the highest hand. Running out of cards results in a fold. If a four is turned over, the player receives another card, face down, from the dealer. Threes and nines are always wild.
