Each player is dealt two hole cards and a bet is made. Then the dealer place three cards, face up in the middle of the table. Each player, beginning from the dealers left if offered the opportunity to buy one of the cards or take a free one from the top of the deck.
The cards in the store are offered at graduated prices. Example: first card is .05, second card is .10 and third card is .25 and as cards are bought a new card is added and cards not bought move up.
Once all players have two hole cards and four up cards the last card is dealt down as in seven-card stud. If no player buys a card in any given round then the store cards are replaced.
Of course there is a betting round after all players have bought or been given an up card.
A good strategy is to buy cards that you know your competition might want to buy.
