Definitions

  • the invention relates in general to wagering game methods. More particularly, the invention relates to a lottery game that is hosted by a central computing system, wherein entries are memorialized on tickets issued at electronic terminals and drawings are held at specific times.
  • a lottery is a wagering game sponsored by an organization, such as a government.
  • an "online" lottery game is a wagering game for which a player purchases an entry that is memorialized on a paper ticket that is dispensed at an electronic terminal. The transaction is recorded by a central computing system.
  • An online game is consummated by a "drawing," a process by which winning indicia are determined.
  • the drawing may be a physical process, such as releasing numbered balls into a transparent chamber, wherein the balls are mixed by jets of air.
  • the winning balls may be selected by allowing one or more balls to pass to a display area such as a clear tube.
  • the winning indicia may be determined by a computer process driven by a random number generator.
  • electronic drawings have become more popular as they are less expensive. Once the drawing has been conducted, prizes are awarded based on comparisons between a player's and the winning indicia.
  • the most well known lottery games are "matrix" games, a matrix being a range of numbers, e.g., 1 to 50.
  • An entry comprises a subset of the matrix chosen by or assigned to a player.
  • the lottery organization conducts a drawing to produce the winning numbers. Prizes are awarded based on matches between the entry and the winning numbers.
  • a variation on this idea is the multi-matrix game.
  • an entry may comprise subsets of two matrices of numbers. Prizes are awarded based on the matches between an entry's subsets and the respective winning subsets.
  • Such are the popular multi-state Powerball ® and Mega Millions ® lottery games for which the top prize is typically in the tens or hundreds of millions of dollars.
  • the lottery Another common type of online game is the "numbers game.” Such are the well-known “Pick 3" and Pick 4" games, wherein an entry comprises a sequence of digits. The lottery randomly selects a sequence of digits. Depending on the bet type, the player is awarded a prize based on whether the digits comprising his number match the digits in the winning number in exact or in any order. (There are variations.)
  • the prizes for numbers games are several magnitudes lower than that of jackpot-driven matrix games.
  • the prizes may be fixed, i.e., a straight bet (i.e., matching 3 digits in exact order) may pay out 500 to 1, or the prizes may be pari-mutuel.
  • the day-to-day cost to the lottery may be erratic (e.g., a popular number such as 777 costs the lottery a huge payout). But a numbers game will correct itself over time based on the laws of probability. Numbers games have their roots in illegal street games and tend to be more popular in geographic areas that have such a history.
  • raffles are events that raise funds (e.g., for charities, governments, etc.) and long predate online computer technology. Tickets with unique identifiers are purchased by players. Identifiers are randomly selected from the pool of those purchased and prizes are awarded. Online raffles simply expand on their old-fashioned counterparts by allowing broader participation and larger prizes, made possible by computer technology. Nonetheless, online raffles require more management than other online games. Unlike a numbers game, a conventional raffle will not "correct” itself over time. If sales don't support guaranteed prizes, the lottery will lose money. For this reason, raffles are usually "special events," rather than regularly scheduled games, to allow the lottery to devote the necessary attention. However, raffles show promise in providing a viable way for lotteries to raise price points, as raffles typically have higher price points than other online games.
  • a monitor game comprises a network of television-like monitors deployed across a jurisdiction, usually in age-restricted environments such as bars. As with other online games, players purchase tickets. Drawings are held at specific intervals and the results are displayed on monitors, which are the same for each monitor across a jurisdiction. Drawings are fast-paced, conducted at regular intervals, up to hundreds of times per day.
  • the most well-known monitor game is that of Keno. Keno is a matrix game where 20 numbers are drawn from 1 to 80. Players are allowed to decide the number of numbers to select as well as the actual numbers. There are different prize tables based on the number of selected numbers. There are other less common monitor games besides Keno, e.g., animated, simulated horse races with bet types similar to those at racetracks.
  • Raffles have already proven reliable revenue generators for lotteries. However, they are comparatively labor-intensive as they require more planning and coordination. It is the goal of the inventive game to provide a more systematic, automated raffle game while retaining the old-fashioned charm of a raffle. As an example of the low-maintenance, automated nature of the inventive game, it will be disclosed how this invention can be embodied as a fast-paced monitor game, like Keno.
  • a player selects a letter from the alphabet.
  • the lottery extends this selection to a unique raffle identifier, which is memorialized on a paper ticket.
  • the first stage of the game is the spinning of the "raffle wheel," which comprises slots occupied by letters of the alphabet interspersed with prizes. If the outcome is a letter, a group of players is simultaneously awarded prizes, i.e., entries for which players selected the winning letter each receive a prize. Otherwise, the outcome of the first stage of the drawing is a prize, from which follows a second stage to the drawing: an individual raffle drawing for the winner of this prize.
  • An embellishment on this idea is that a slot on the raffle wheel may indicate a plurality of prizes (rather than a single prize), in which case, the second stage would comprise a corresponding plurality of raffle drawings for individual winners.
  • a multi-wheel embodiment adds a step to the single-wheel embodiment: the raffle wheel used in the drawing is selected from a system of wheels. This allows the inventive game to be embodied in such a way that there is no minimum sales requirement. In particular, the invention can be fully automated as a fast-paced monitor game, like Keno.

  • the lottery may prefer to not include the quick-pick option for individual panels to avoid being held responsible for offensive words. Instead, quick-picks could be provided upon a verbal request to the sales agent and would consist of a contiguous segment of the alphabet, e.g., ABCDE, BCDEF, etc., none of which form offensive words.)

  • Example 3 This embodiment employs the raffle wheel 900 in Figure 9.
  • This wheel is similar to the wheel 400 in Figure 4, except that in place of the slot for a jackpot there is a special symbol, a palmetto tree 901, South Carolina's state tree. There is a special prize fund that finances these prizes. Every time the palmetto symbol is hit, $250,000 is automatically donated to the fund. The price is $5 with a $20 5-for-the-price-of_4 option.

  • Each jurisdiction is assigned a probability equal to the proportion of entries from that jurisdiction out of all of the entries 1303.
  • a jurisdiction is randomly selected subject to this probability distribution 1304.
  • An entry is randomly chosen from the selected jurisdiction 1305 and the chosen entry is eliminated from the random sample 1306.
  • the number of entries from that jurisdiction is decremented by 1 1307. (This will appropriately adjust the probability assigned the jurisdiction if there is another raffle winner to be drawn.)

  • Wheel 1 is fundamentally different from the other wheels in that there are only 26 slots, one for each letter of the alphabet and no slots for raffle prizes.
  • Wheel 4 is the premium wheel in that it comprises the highest raffle prizes as well as the jackpot.
  • Each wheel has a colorful design and a fanciful name.
  • each of the four wheels is assigned a probability based on the number of entries.

  • An entry is randomly selected and displayed in an animation 2105 such as a raffle ticket being pulled out of a hat.
  • the winning raffle identifier and prize are displayed on the monitor 2106.
  • Example 6 Figure 22 illustrates a variation of the embodiment in example 5. This embodiment is exactly the same as that in Example 5, except that Wheels 1 through 4 are equally weighted wherein the number of entries n > 11,106.
  • This embodiment represents the philosophy that for a very large number of players it is more aesthetic for the wheels to be equally weighted as opposed to the entire weight being on the premium wheel, Wheel 4.
  • Example 7 This embodiment is the same as that in Example 5, except that it offers a deluxe play for $5 (vs. $2 for a regular play). In a deluxe play, the letter-match prize is $100 (20 times the price point), whereas in a regular play the letter-match prize is $20 (10 times the price point).
  • An exemplary ticket 1600 is in Figure 16.
  • the probabilities assigned to the wheels as well as the jackpot contribution is still based on the number of entries, regardless of the price point. That way, the $2 player is indifferent to whether or not another player opts for the $5 deluxe play:
  • the weightings of the wheels and the size of the jackpot is the same either way.
  • a constant 70% the return for a deluxe play decreases as the number of entries increases.
  • n 1, the return for the deluxe player is 89.5%.
  • the lottery actually makes less on a $5 purchase than a $2 purchase. But as n increases the actual profit, in terms of dollars, for a $5 entry approaches $1.38 (as opposed to a constant $0.60 for a $2 purchase).
  • the player selects a letter 2302 that is extended to a unique raffle identifier 2303. Increment the Price Point counter 2304. (In some embodiments it is necessary only to track the number of entries. In others, it is necessary to track the number of entries at the different price-points.) Are letter-match prizes to be assigned at issuance as is the case of some embodiments 2305? If yes, assign the letter- match prize before the ticket is printed 2306. (It may be the case that the potential letter- match prize is printed beside the raffle identifier.) Issue the ticket 2307.
  • the drawing may be conducted. Is it a multi-wheel system 2308, as would be the case for a monitor game? If yes, assign probabilities to each of the wheels based on the number of entries 2309. Randomly select one of the wheels subject to the probability distribution 2310. Contribute the appropriate amount to the progressive jackpot or special prize fund, whatever the case may be 2311.
  • the raffle wheel is spun 2312. Does it land on a letter 2313? If so, the drawing is finished. Otherwise, the raffle wheel has landed on a prize (or plurality of prizes) and a drawing (or drawings) for individual winners is held 2314.
  • the lottery is in a position to assign prizes to the entries 2315. Prizes can now be publicized, such as on television, in the newspaper, on a website, or on a monitor 2316 and players can redeem their tickets 2317.
  • the inventive game should be distinguished from a recent patent by the same inventor: "Extension to a lottery game for which winning indicia are set by selections made by winners of a base lottery game" disclosed in U.S. Pat. No.7,213, 811.
  • Extension to a lottery game a player selects a symbol, which is assigned a raffle number.
  • a player in the inventive game selects a letter that is augmented to a unique raffle identifier. After this, "Extension to a lottery game” and the inventive game proceed differently.
  • the "Extension to a lottery game” comprises two games with two outcomes for which the outcome of one depends on the outcome of the other:
  • the winning symbol is defined to be that selected by the winning raffle winner.
  • the inventive game comprises one game for which there is one winning outcome: a letter, or, a raffle prize (or prizes).
  • Extension to a lottery game The essence of "Extension to a lottery game” is that player selections influence the outcome of the game. A popular symbol is more likely to win because it is more likely to have been chosen by the winning raffle player. In the inventive game, player selections have no affect whatsoever on the outcome of the game. Also, in “Extension to a lottery game,” prizes based on the player-selected symbol must be paid on a pari-mutuel basis. This is because the probability of a symbol winning is not known in advance, but depends on player selections. In the inventive game, all game indicia have an equally likely chance of winning. Therefore, letter-match prizes for the inventive game may be awarded in a variety of ways, including fixed prizes.

Abstract

Selon l'invention, un tirage au sort dans un jeu de loterie comprend une ou deux étapes. Dans la première étape, on fait tourner une roue. Si la roue indique un intervalle occupé par des symboles de jeu, tous les joueurs d'un groupe gagnent simultanément, le tirage étant alors terminé. Si tel n'est pas le cas, la roue indique un prix, un tirage au sort pour un gagnant de ce prix étant alors reporté à une seconde étape. Des modes de réalisation à une seule roue ou des modes de réalisation plus complexes à plusieurs roues sont possibles, un mode de réalisation à plusieurs roues présentant au moins l'avantage de ne pas requérir de niveau minimum des ventes.
