  • Patent number: 6899619
    Abstract: The method of entertainment “Stos” is an adaptation for casinos, videogame machines and computers of the most popular game of chance in the eighteenth and nineteenth centuries. It is also known as Bank Table, Shtoss and Pharaon. In a casino, the game takes place on a table on which there is a game field with suit-less cards and four suit cards: spades (), clubs (), diamonds (?) and hearts (?). The game generally uses one or several standard 52-card decks. The players bet that the card they select will be dealt out of the deck on an even interval. To do so, they place their chips on a suit-less card that they pick on the game field. They may also predict the suit of their card by placing a bet on one of the suit cards. After the cards are shuffled and cut, the dealer places the cards face down on the table and draws the cards in order, two at a time. All bets on a card are considered played as soon as the first matching card is dealt from the deck.

  • Publication number: 20040248635
    Abstract: The method of entertainment “Russian poker” is based on the popular card game and is intended for gaming halls. The game has more potential and is more absorbing because the player has the opportunity to exchange any amount of cards, insure his game, make bets on bonuses and exchange the dealer's cards. Furthermore, the player's ability to buy a sixth card and receive payment for two combinations evens out the odds for the player and casino. The use of a standard deck of cards in its gaming machines brings the game closer to reality, and allows for the exclusion of a random number generator from the machine's construction, which enhances the player's trust in the reliability of its randomness.
