Split seven cards into two hands and beat the dealer with both.
Seven cards, split into two poker hands, and you must win both to win the bet. The deck includes one joker.
It is not fully wild. It completes a straight or a flush, and otherwise counts as an ace.
Divide your seven cards into a five-card high hand and a two-card low hand. The one rule that matters: the five-card hand must rank higher than the two-card hand. Setting them the other way round is a foul and loses automatically.
The two-card hand can only ever be a pair or high card, so the real question is which pair to send back and which to keep in front.
Your high hand is compared with the dealer's high hand, and your low with their low.
Win both and you are paid, usually with a commission taken. Lose both and the bet is lost. Win one and lose one and it is a push — the bet comes back.
The dealer wins exact ties, which is where the house edge lives.
Because pushes are so common the bankroll lasts a long time, and the game is one of the slowest in a casino. The house way — the fixed method the dealer must use to set their own hand — is printed and available on request, and copying it is a perfectly good strategy.
