  • the modified twenty-one or black jack game is a casino table game, for example, for a dealer and 1 to 7 players. It can also be played as an individual video casino game. It contains at least two unique features: 1) A special modified black jack game payoff table which encourages the player to place additional wagers on the Dealer's hand. These wagers are independent of the normal Black jack wagering, and therefore, do not effect the normal Black Jack strategy.
  • Each modified black jack game bet has been subdivided into two levels of payoffs, the commonly occurring level with odds ranging from, for example, (2 to 1) to (6 to 1) , and the Ace Up Level (the dealer's up card has to be an Ace) with odds ranging from, for example, (10 to 1) to (40 to 1) .
  • the Game Device is a standard felt-covered table, similar to a Black Jack table with a special play-and- bet design, stenciled onto the felt, in front of each player, or a video gaming device, with, for example, five numbered buttons (17, 18, 19, 20 & 21), one bust button, and the other buttons necessary to play normal Black Jack.
  • the normal rules of black jack apply, but in addition, the player may bet that the dealer ends up or finishes with a 17, 18, 19, 20, 21 or bust.
  • Each of these possibilities are mandatory dealer results because the dealer must hit on anything lower than 17.
  • the dealer is going to end up with any of those 5 final totals, 17-21 or bust.
  • the player can bet on any one or more of the dealer results, in addition to, or even instead of betting on beating the dealer.
  • the player can therefore protect himself, and bet on some of the possible winning numbers of the dealer.
  • the player also gets to bet on the dealer results 17, 18, 19, 20, 21 or dealer bust.
  • FIG. 1A illustrates the table layout of the modified black jack game.
  • the table layout includes player positions 2, 4, 6, 8, 10, 12, and 14. Of course, any number of players may be included in the modified twenty-one game, subject to the limitation on the number of cards in the deck(s) .
  • Area 16 on the table includes various indicia providing collateral or additional rules, such as payoffs for player black jack (3:2), standard insurance payoffs (2:1), and the like.
  • FIG. IB illustrates an enlarged view of the table layout of the modified black jack game for an individual player. In FIG.
  • player position 2 includes individual dealer bet areas 18 (for dealer 17) , 20 (for dealer 18) , 22 (for dealer 19) , 24 (for dealer 20) , 26 (for dealer 21) , and 28 (for dealer bust) .
  • player position 2 is designed in a pyramidal or triangular shape to facilitate wagering.
  • Each wager position includes the odds or rate of return for the wager.
  • these odds have been separated or divided into odds designed for the dealer obtaining a hand of 17, 18, 19, 20, 21 or bust with any card combination, and an enhanced payoff when the dealer achieves a hand of 17, 18, 19, 20, 21 or bust with a predetermined combination of cards.
  • the predetermined combination requires the dealer to have an ace card first, and then the remaining cards to form the hand of 17, 18, 19, 20, 21 or bust.
  • other predetermined card combinations could be used to provide the enhanced payoffs for the modified black jack game.
  • the significant aspect of this feature of the modified black jack game is that enhanced payoffs are provided for dealer hands that match a predetermined card combination.
  • various card combinations can be used, and which are contemplated by the present invention.
  • the special modified black jack game bet makes no difference or is unaffected with respect to what the player does in connection with this bet. The player can win or lose; it does not make any difference because the modified black jack game bet is an independent action.
  • the payoffs are as follows: For example, if the player bets 17, 18 or 19, he gets 5 to 1, i.e., a total of 6. For 20, the player gets a total of 4 , or 3 to 1, for 21 the player gets 6 to 1 or a total of 7, and for bust the player gets 2 to 1 or a total of 3. There are 16-10 cards in the deck, so the number 20 comes up more often, and therefore, the player only gets 3 to 1 odds. Thus, the dealer has a better chance of getting a 20 than a 17, 18, 19 or 21.
  • FIG. 2A is an illustration of an exemplary payoff table for the modified game of twenty-one where the odds have been determined based on a combination of six decks of cards.
  • FIGs. 2B-2G is an alternative payoff table according to the modified game of twenty- one. These payoff tables are the same, with the exception of the Casino's hold, depending on the number of decks, and card playing strategy.
  • FIG. 2B is for playing the modified black jack game with six decks (similar results for 4 or 8 decks as well)
  • FIG. 2C is the same as FIG. 2B, but with taking into consideration a player using a card counting strategy to maximize the chances of winning.
  • Both FIGs. 2B and 2C also require the dealer to stand on any card hand 17 or higher, and are based on running simulations for one million deals.
  • FIG. 2D is for playing the modified black jack game with six decks (similar results for 4 or 8 decks as well)
  • FIG. 2E is the same as FIG. 2D, but with taking into consideration a player using a card counting strategy to maximize the chances of winning. Both FIGs. 2D and 2E also allow the dealer to hit on the standard soft 17 and the dealer must stand on other card combinations of 17 or higher.
  • FIGs. 2D and 2E are based on running simulations for one million deals.
  • FIG. 2F is for playing the modified black jack game with only one card deck
  • FIG. 2G is the same as FIG. 2F, but with taking into consideration a player using a card counting strategy to maximize the chances of winning. Both FIGs. 2F and 2G require the dealer to stand on all card combinations of 17 or higher.
  • FIGs. 2F and 2G are based on running simulations for one million deals.
  • the payoffs/returns include the ability to fine tune the hold or the take of the game operator, such as a casino, using, for example, the special payoff/return when the dealer has an ace + 6 for the number 17, an ace + 7 for the number 18, an ace + 8 for the number 19 or an ace + 9 for the number 20.
  • the player can also protect certain numbers by picking them off by betting on them and so protect or recover his original wager even though he loses to the dealer including his original wager. For example, if the player winds up with number 18 and the dealer gets 20, the player can recover his initial wager if the player also made a modified black jack game wager on 20. If the player bet $10 to win and $5 on 20, the player winds up winning $10 in total because he won $20 from the modified black jack game bet and lost $10 on the initial wager or regular black jack bet.
  • the modified black jack game includes the advantage that it is totally independent of the regular modified black jack game, as well as totally independent of player actions. Thus, there is no strategy conflict or a player cannot increase their chances of winning by playing to bust, and the like.
  • modified black jack game can be played at any standard black jack table and does not affect the basic game of black jack. People do not have to play the modified black jack game wager or even the regular wager if they place the modified black jack game wager. As indicated above, modified black jack game is a variation of black jack without any conflict with the existing black jack game rules.
  • the modified black jack game may also be played on a stand alone computer or a computer in a network environment. See the different patent applications that have been incorporated by reference .
  • the modified black jack game includes the ability to fine tune the hold for the game operator/casino. By jiggling or modifying the return for the modified black jack game for the special return of ace + 6, 7, 8 or 9 combination, payoffs can be fine tuned at 98%, 94%, 96%, and the like.
  • the casino hold can be fine tuned with ease. This is very important to the casino.
  • the casino hold is 5%.
  • 12 to 1 is offered for 17 for an ace and a 6 and a 6 to 1 otherwise, by changing the 12 to 1 to a 15 to 1 (as well as the other ace + 7, 8 or 9) the casino hold is now changed to 2%, from 5% previously.
  • an additional 3 to 1 is added to the ace + 6, 7, 8 and 9 returns, the overall chances are 98%, and the casino keeps 2%.
  • an additional 3 to 1 may be subtracted from each of the ace + 6, 7, 8, and 9 returns resulting in a total hold of 8%.
  • the modified black jack game provides higher payoffs than other black jack type games. For example, when players buy insurance for dealer black jack, the player is normally only getting 2 to 1 odds. However, the modified black jack game pays much higher as illustrated in FIGs. 1A, IB, and 2. As discussed, FIG. 2 is a payoff table that has specific advantages in terms of percentage of hold versus odds or payoff provided the player.
  • Another reason for the advantage of this fine tuning of the probabilities feature is that it allows the creation of even odds on the bets. Otherwise, without the fine tuning feature, the odds would likely be more like 5 to 2 , 9 to 2 , 13 to 5, which may be very confusing to the players. The use of even odds advantageously eliminates all this potential confusion.
  • a further advantage of the modified black jack game' design is that it prevent collusion among the players. That is, the modified black jack game extends the concept of making secondary bets to making secondary bets on the dealer performance. Thus, the dealer performance is unrelated to and does not affect the player's strategy of playing the game.
  • FIG. 3 is an illustration of the basic game rules/procedure for playing the modified black jack game.
  • the game begins with the player optionally making the initial wager for playing the basic black jack game in step S2.
  • the player is also asked whether the player wants to make the additional modified black jack game wager on one or more of 17, 18, 19, 20, 21 or bust in step S4.
  • the regular game of black jack is played in step S6.
  • the dealer next plays to completion, even though all the players may have busted and lost their initial wager to ensure that the dealer has the results needed for scoring for the modified black jack game wager in step S8.
  • Step S12 also includes evaluating the dealer's hand to determine whether the dealer got a 17, 18, 19, 20, 21 or bust with an ace and other card and also to determine whether the player is eligible to receive an enhanced payoff.
  • the modified black jack game bet places that have been bet on or scored are then determined with respect to the appropriate player, and compared to the dealer's final hand. The player's that have won are then awarded the appropriate reward.

  • FIG. 26 is a screen display of when the player has doubled down the bet as in FIG. 25, and after the player has won twice the initial bet of 1 credit.
  • FIG. 27 is a screen display of when the player bets 1 credits on the regular black jack game, and 5 credits on the dealer 20 position in modified black jack game.
  • FIG. 28 is a screen display of when the dealer receives or sticks on a 20, and the player busts in accordance with the bet of FIG. 27. Even though the player loses the regular black jack game and wager, the player still wins the modified black jack game wager because the player has bet 5 credits that the dealer will result in a 20 point card hand.
  • the modified black jack game is a natural multi - player game against a dealer.
  • This multi-player feature may be used in the video game machine . Assume that the video game allows for two or more players then the following is possible: a) an individual can play more than one hand at a time against the dealer. b) two players can share the same machine, using a "love seat” concept the two players share the winnings and losses. A perfect game for couples or friends . c) two or more players can play using separate
  • the wagering scheme contains an inherent fine tuning mechanism for modifying the casino's hold percentage. That is, the Ace Up bonus payoffs can easily be changed to allow for minor hold percentage changes. This has great importance to the casino in jurisdictions where the hold percentage is constrained (especially true for the video game version) . 5. Most importantly, the modified black jack game does not prevent a player who wishes just to play generic Black Jack from doing so. Therefore the casino does not have to worry about having separate tables for standard Black Jack - they are contained within the modified black jack game tables.
  • the first additional payoff is when the dealer obtains a 20 score by obtaining the cards in the sequential order of ace, 2, 3 and 4. If a player bets on 20 (or perhaps no bet may be required for this first additional payoff) and the dealer shows an ace and winds up with 20 consisting of an ace, 2, 3 and 4, precisely those cards in that sequence, the player obtains increased odds, for example, 100 to 1. It is not easy for the dealer to get 20 without this sequence of ace, 2, 3 and 4, because, for example, ace, 2, 4 is 17 and the dealer must stick in accordance with the standard black jack rules. An ace, 3, 4 is 18 and the dealer must also stick with this number. The odds of an ace, 2, 3, followed by a 4 are a few thousand to 1, providing the greatly enhanced payoff .
  • a second enhanced payoff is if the dealer starts with an ace and winds up with ace, 2, 3, 4, 5, 6, which adds up to 21 and that can only be accomplished in one particular way.

  • the dealer does not have the option of treating the ace as a 1 or 11 value. Rather, if the ace will bust the dealer, then the dealer must treat it as a 1.
  • This second enhanced payoff is even greater than the first payoff, and may be, for example, 25,000.
  • Both the first and second enhanced payoffs are totally consistent with the rest of the modified black jack game because they require the dealer to have as the first card an ace -- which compliments the already enhanced or modified black jack game payoffs for ace + (6, 7, 8, or 9) dealer results, described in detail above. Thus, players become excited when the dealer's first card is an ace because the payoffs are greatly enhanced.

  • a third enhanced payoff/reward is if the dealer has, for example, the 21 score using the cards ace, 2, 3, 4, 5, 6, and all cards are in the same suit.
  • This third enhanced payoff would be, for example, the million dollar payoff.
  • this million dollar payoff does not even effect the overall odds of the modified black jack game because the chances are so veryly small of obtaining this million dollar payoff .
  • the million dollar payoff may be funded as a progressive jackpot with two different tiers of payoffs. Since this third enhanced payoff is so rare, the player might not even be required to make any bet whatsoever on the dealer, i.e., no modified black jack game bet might even be required, or a modified black jack game bet on 20 or 21 may not be required. In the progressive jackpot, a quarter of 1% of every play may be deposited against the progressive as an escrow account, and it builds up and builds up and once in awhile somebody collects.
