Definitions
- the present invention relates to a method and apparatus for generating a result of a racing game which enables fixed odds betting on the game, the result of the racing game being generated from identifiers drawn in an identifier selection game.
- Keno is an ancient Chinese numbers game based on the drawing of 20 balls from a cage containing 80 balls numbered 1,2, .... ,80. In the last twenty or so years the game has become fully computerised and this has lead to a very fast game with a draw every 3 - 5 minutes. Many jurisdictions allow the use of an internal software based result generation technique using an approved pseudo Random Number Generator or an external "Black Box" result generator based on a software pseudo-Random Number Generator or a hardware white noise sampler.
- Keno results are typically graphically presented as an 8 x 10 grid (matrix) as shown in Figure 1.
- Trackside is a game developed by the present applicant that provides an animated race between a number of "participants” .
- Players are offered fixed odds on a sub- set of standard horse racing bet types.
- the win odds are nominated by the game operator and the system derives the place, quinella and trifecta odds from these using published algorithms.
- Each game result is generated by either an approved internal software algorithm or an external mechanical ball draw taking into account the unequal chance of winning of each "participants” .
- a Trackside result comprises the first three “participants” . These are called the race “placings" .
- Second is determined by the same algorithm as used to determine the winner excepting the trial ("race") is between 11 participants and their respective chance of winning the trial for second has been adjusted to take account of removal of the winner of the trial for first.
- Third placing is similarly determined by a further trial between the remaining 10 participants .
- Trifecta bet players bet on three contestants coming first, second and third in exact nominated order. Odds are offered based on each permutation of the trifecta. Accordingly, it would be desirable to generate a result for a Trackside type race game from a Keno type identifier draw game as this will allow Trackside type games to be run concurrently with a Keno type game without the need to run a separate random number generator. Providing such a game may also provide an additional enjoyable game to improve player enjoyment in conjunction with a Keno type game.
- the invention provides a method of generating a result of a racing game having a plurality of participants to enable fixed odds betting on the racing game, the result of the racing game being generated from the result of an identifier selection game, the method comprising: allocating unique subsets of a set of identifiers used in the identifier selection game to each of the plurality of participants; defining a ranking of said participants from highest to lowest; running said identifier selection game by randomly selecting a result subset of identifiers from the set of identifiers; and determining first place in said race by determining which of said plurality of participants has the most identifiers of said result subset in the participant's allocated subset, and if two or more participants have the same number of identifiers in their respective allocated subsets, determining first place by determining which of the two or more participants is ranked highest.
- generating the result involves generating second place, and wherein if first place was determined by rank, second place is determined by the next highest rank, and if first place is determined by the number of identifiers in the allocated subset of the first placed participant, second place is determined as being the highest ranked participant which has the next greatest number of identifiers in their allocated subset .
- results of the race are random but biased in accordance with the ranking of participants thereby modifying the odds of participants winning and allowing different odds to be offered on that basis.
- the highest ranked participant will have the lowest return on outlay
- the second ranked participant will have the second lowest return on outlay with the return on outlay increasing to a greatest return on the lowest ranked participant.
- the spread of the odds can be varied by allocating subsets of different numbers of identifiers to at least some of the participants. Typically, this will involve allocating larger subsets to higher ranked participants than to lower ranked participants so that the relative odds of each participant winning are consistent with the participant's ranking. However, this need not necessarily be the case and larger subsets could be allocated in another way - for example, randomly - to obtain other interesting spreads of odds.
- the participants are horses in an animated horse race.
- the identifiers will be numbers.
- the set of numbers is eighty numbers and the result subset consists of twenty numbers randomly selected from the set of eighty.
- the number of participants and the sizes of the subsets can be varied in a number of ways. For example: eight participants with subsets of ten; ten participants with subsets of eight; twelve participants with the eight highest ranked participants having subsets of seven and the four lowest ranked participants having subsets of six; or twelve participants with two participants having subsets of eight, six participants having subsets of seven, two participants having subsets of six and two participants having subsets of five.
- the set of identifiers are displayed as a matrix and contiguous portions of the matrix are allocated to each participant when allocating the subsets, whereby it can readily be determined by inspecting the matrix to which participants identifiers in said result set belong.
- Apparatus for generating a result of a racing game having a plurality of participants to enable fixed odds betting on the racing game the result of the racing game being generated from the result of an identifier selection game comprising: an identifier selector for randomly selecting a result subset of identifiers from a set of identifiers to thereby generate a result of the identifier selection game; and a result generator for determining first place in said race by determining which of said plurality of participants has the most identifiers of said result subset in a participant allocated unique subset of identifiers, and if two or more participants have the same number of identifiers in their respective allocated subsets, determining first place by determining which of the two or more participants is ranked highest from pre- allocated rankings of said participants from highest to lowest.
- the result generator determines second place by the next highest rank, where first place is determined by the number of identifiers in the allocated subset of the first placed participant, the result generator determines second place as being the highest ranked participant which has the next greatest number of identifiers in their allocated subset.
- the result generator can determine further places as necessary in an order defined firstly by the number of identifiers and secondly by the relative rankings of the participants .
- the spread of the odds of participants can be varied by pre-allocating subsets of different numbers of identifiers to respective participants .
- Figure 1 is a matrix of Keno results
- Figure 2 is a schematic diagram of an apparatus for determining the result of a game.
- Figure 2 is a schematic diagram of an apparatus for determining the result of an electronic game of the preferred embodiment.
- the electronic game is a horse racing game called TracksideTM where players bet or wager on the result of the electronic game.
- the individual horses in the electronic game provide a plurality of participants which can be bet upon.
- Players of the game can place fixed odds bets on the horses in the same manner as fixed odds bets can be placed on conventional horse races .
- To stimulate customer interest in such a game it is necessary to allow players to bet at a variety of horses at different odds.
- the electronic game is controlled by software run by a computing device in the form of a processor of a host computer 101.
- the host computer 101 instructs the graphics engine 102 to create the horse race simulation.
- the graphics engine 102 then causes the simulated horse race to be displayed on displays 105.
- the preferred embodiment provides a technique for manipulating the results of identifier selection game such as Keno where there are set of eighty numbers from which a subset of twenty numbers are selected to generate the result of the racing game.
- the racing game is run in conjunction with the Keno game so that when the result of the Keno game has been determined, simulation of the Trackside game occur in conjunction with display of the Keno result.
- the method involves allocating unique subsets of a set of eighty numbers (identifiers) to each of the plurality of participants.
- a ranking is also allocated to the participants form highest to lowest.
- horse one has the highest ranking, horse two the second highest ranking etc.
- a Keno draw a set of twenty numbers referred to herein as the results subset is drawn from the set of numbers.
- First place in the race is determined by determining which of the horses has the most numbers of the result subset in their allocated subsets. If two or more horses have the same number of identifiers in their respective allocated subsets, first place is determined by determining which of the two or more horses is ranked higher.
- Subsequent places are also allocated in an order defined firstly by the number of identifiers of a horse's subset which are in the result subset and secondly by the relative rankings of the participants. Thus, the bias towards higher ranked horses will be continued in the allocation of further places.
- the result is determined by determining the identity of the first three place getters.
- Players can bet on the chance of an individual horse winning or the chance of a horse obtaining a place.
- Players can also bet using other conventional horse racing bet types such as: quinellas where the player bets on the first and second place getters in a race; - lo an exacta where the bet is placed on the first and second places but where order is important; and on a trifecta where bets are placed on the first three place getters .
- the subsets of numbers which are allocated to individual horses are preferably chosen so that they are next to one another (i.e. contiguous) in the matrix of Keno results which is normally displayed as an eight by ten grid or two four by ten grids as shown in Figure 1.
- the results are displayed by highlighting individual numbers on the grid of eighty numbers to show that they belong to the result subset as shown in Figure 1 by the bold numbers.
- a Keno draw involves an animation of the results which have previously been chosen using a standard technique such as random number generation. If, as in one embodiment, this is displayed alongside an animated horse race the player can see for example on one display screen the Keno results as they are drawn and on the other display screen the animated horse race and so will be encouraged if they see that two or three numbers have been drawn early in the Keno draw in the subset which belongs to the horse they have selected, thus building excitement in the game.
- Example 1 Several examples of possible numbers of horses and subset sizes will now be described to further illustrate the preferred embodiment.
- Example 1 Several examples of possible numbers of horses and subset sizes will now be described to further illustrate the preferred embodiment.
- each participant (runner) is represented by ten Keno balls in the matrix as shown in Figure 3 where each horse has a row of Keno numbers. With eighty Keno balls in the Keno matrix and twenty drawn Keno balls relevant to determine race result there are 796,510 different outcomes of ball quantities drawn against each runner.
- each runner has the same quantity of Keno balls but when two runners have the same quantity of balls drawn, the lower numbered runner (i.e. higher ranked) ranks above a higher numbered runner.
- the order of the balls drawn from Keno is not relevant to derive the result.
- the win, place, and quinella dividends are shown in Tables 1, 2 and 3 respectively including the return to player (RTP) .
- this provides a still greater spread of odds for wins, places, quinellas and trifectas than in the previous examples. Indeed, the least likely trifecta in this Example will produce a payout of about $600,000 unless a cap (e.g. $100,000) is applied to the trifecta as may be appropriated. This is significantly larger than the largest trifecta for example 2 which is in the order of $16,000 for an 80% return to player.
- a cap e.g. $100,000
- any other appropriate arrangement of number of participants and size of subsets can be chosen in order to vary the spread of the odds . Considerations will include providing an appropriate spread of odds from highest to lowest ranked horse. Typically where subsets of different sizes are allocated, this will be done by allocating bigger subsets of identifiers to the higher ranked horses and lower numbers to lower ranked horses to thereby spread the odds. However, persons skilled in the art will appreciate that other permutations may be desirable in order to vary the odds. For example, if it is desired to have one or two horses in the race which have more similar odds than are otherwise available because of the pre-eminence given to the highest ranked horse.
- the highest ranked horse need not be numbered horse number one and that other horse numberings could be used or indeed names could be used in order to identify horses.
- the term "rank" is used to indicate the order in which horses are favoured in determining the result.
- the racing game could be run using ball draw out of different numbers of balls so that it can be run in conjunction with other number draw games or, run independently of a ball selection game.
- the number of identifiers in the set of identifiers and the number of identifiers in the result subset can be varied in order to vary the odds of the game and the participants are horses .
- the method of the preferred embodiment can readily be encoded in software to run on the host computer 101.
- the host computer 101 may include the identifier selector which selects a random subset of identifiers from a set of identifiers or the identifier selector may be provided by an alternative piece of apparatus.
- a computer configured to generate a Keno result to thereby keep the two processes separate.
