Description

22/08 ' 00 TIDE 18: 47 FAa B1 T 3229 3384 CLTLLEN & C0. 11003 ' 1 A METHOD OF AND SYSTEM FOR OPERATING GAMING MACHINES
Field of the Inv~ntion The present invention relates generally to gaming machines s and, in particular, to a plurality of inter-linked gaming machines that provide a jackpot prize-winning mode of operation. The jackpot prize-winning mode is additional to the prize-winning that occurs during normal play on the machines.
to Description of the Prior Art Systems for awarding jackpot prizes that are separate from the normal prizes available during the normal playing of gaming machines are known. These systems consist of linked gaming machines communicating with a central computer. The central computer receives information from the ~s gaming machines relating to each play on a machine and, sometimes, the value of the wager on the machine. A jackpot prize pool accumulates with each machine play and the accumulated jackpot prize is available on a display. The jackpot prize is awarded when a randomly selected jackpot prize value is reached and the prize is awarded to the player of the machine who ao was responsible for causing the accumulated jackpot prize to reach or exceed the random value.
Another system uses a prize accumulation phase and a prize awarding phase which are independent of one another. During the prize accumulation phase a starting or initial value is determined as a monetary 2s value between prescribed limits and a random prize value between two limits is added to the initial value. A percentage accumulation is caused in a prize pool when gaming machines are played. When the prize pool equals the sum of the random prize value and the initial value, the prize pool is frozen and the prize accumulation phase is concluded. A prize-awarding phase is then a o commenced and a "win count" value is randomly selected. Each player of a 22/08 ' 00 TIJE 16: 48 FAZ 61 7 3229 3384 CLTLLEN & C0. f~ 004 machine has a chance of winning the known prize value. The prize-awarding phase is independent of the prize accumulation phase.
Each play-input event during the prize-awarding phase is counted and units wagered are separately accumulated in an "excess pool".
s A processor then compares the number of input events with the _ randomly determined win count. If the number of input events is less than the randomly determined win count the process continues. If the number of input events is greater than or equal to the randomly determined win count a win occurs and the machine whose play was responsible for equaling or exceeding the win io count is recorded as the winner and the player is entitled to redeem the prize.
The excess pool value is then added to the starting value.
It is an object of the present invention to provide a method of and a system for jackpot prize-winning mode of operation, which differs from the previously mentioned systems and encourages machine usage and x~ player enjoyment.
Summary of the Invention According to a first aspect of the present invention there is provided a method of providing a jackpot award for a plurality of gaming zo machines linked by at least one venue jackpot controller to a central jackpot controller, the method comprising the steps of:

Fig. 1 is a block diagram of a non-deterministic jackpot system xo 10. A non~eterministic jackpot system is one in which the triggering of a jackpot win is not dependent on a previous event, and in which there is no increased probability over time of the jackpot being awarded. Thus, the jackpot amount that is offered by the system 10 does not have an upper value limit.
zs The system 10 comprises a Central Jackpot Controller (CJC) 200 communicating with a plurality of Venue Jackpot Controllers (VJC) 300 via a Wide Area Network (WAN) 20. The CJC 200 also communicates with a p8~ta Management System (DMS) 100.
Each VJC 300 is located at a gaming venue having one or more zo Electronic Gaming Machines (EC3M) 40. The EGMs 40 at each venue communicate with an associated VJC 300 and Site Controller 30. The EGMs 40 eouki, for example, be electronic poker machines of the type that are commonly supplied at gaming venues.
The system 10 also includes other peripheral equipment such as zs electronic displays, power supplies and network boards which are not shown in' Fig. 1.
The CJC 200 is the controller at the centre of the jackpot system 10. The CJC 200 is the only device in the system 10 that is capable of triggering a jackpot win.
3 o The VJC 300 is a device whose functions include monitoring 22/08 '00 TUE 18:50 FAa 81 7 5229 3384 CL1LLEN & C0. X1011 . 9 turnover on the EGMs 40, v~rifying the turnover fior validity and transmitting the turnover to the CJC 200. Each VJC 300 also controls and monitors any associated electronic displays (not shown). There can be more than one VJC
300 located at each venue.
The DMS 100 is the user interface to the CJC 200 and VJC 300 devices. The DMS 100 facilitates the uploading of information to the CJC 200 and the receipt of messages from the CJC 200.
The system 10 works on a 6-second polling cycle with the CJC
200 controlling all system functions and timing. The system 10 provides a xo plurality of jackpot levels however, for simplicity, only one jackpot level will be discussed here. It should be noted though that with multiple jackpot levels the functions are the same and all jackpot levels are calculated simultaneously. -Fig. 2 is a timing diagram of the polling cycle of the system 10.
is The polling cycle is commenced at T = 0 seconds when the CJC
200 polls each VJC 300 for the sum of the current accumulated turnover of all EGMs 40 as well as an EGM Cyclic Redundancy Check (CRC) verification number for the associated EGMs 40.
Since the turnover supplied by each VJC 300 to the CJC 200 is zo accumulated turnover, this turnover will include turnover from previous polling cycles.
Cyclic Redundancy Checking is a commonly used technique for obtaining data reliability and is used to protect blocks of data, called frames, from being corrupted. The technique essentialiy consists of appenving an 25 extra n-bit sequence {called a Frame Check Sequence or t=CS) to every frame. The FCS holds redundant information about the frame that enables errors in the frame to be detected. Cyclic Redundancy Checking is one of the most commonly used techniques for error detection in data communications and, as a result, this document will not attempt to explain the theory of Cyclic 3o Redundancy Checking in any more detail as it is well known by those skilled 22/08 '00 TUE 16:51 FAa 61 7 3229 3384 CLTLLEN & C0. f~J012 ' 10 in the art.
The EGM CRC verification number is a number arrived at by calculating a CRC across the turnover contribution of each EGM 40 since the commencement of the previous polling cycle. As an example, assume that s there are three EGMs 40 allocated to a particular VJC 300 at a venue, and the increase in turnover of the EGMs 40 since the commencement of the last polling cycle is 3, 2 and 1, respectively. The EGM CRC verification number is calculated by running a CRC across the 3 then continuing across the 2 and continuing across the 1. The resultant number is the EGM CRC verification number. Even though the EGM CRC verification number is sent to the CJC
200 each polling cycle, it is only used during the jackpot verification process when a jackpot is to be awarded.
In the present embodiment, the current accumulated turnover amounts and EGM CRC verification numbers are received by the CJC 200 ~5 from each VJC 300 approximately 3 seconds after the commencement of the polling cycle at T = 0 seconds.
Upon receiving the current accumulated turnover amounts and EGM CRC verification numbers the CJC 200 checks each current accumulated turnover amount by verifying that the amount sent by each VJC
zo 300 does not exceed a realistic value. At this point it should be noted that the turnover per unit time of an EGM 40 (and, hence, a VJC 300) will have an upper limit which cannot be exceeded by normal play of the EGM 40. Thus, if some of the equipment at a particular venue was tampered with, or malfunctioned in such a way as to simulate a very large turnover in order to 25 influence the jackpot picking process {to be described later), the unrealistic amount would be identified by the CJC 200 which would then take appropriate action.
The current accumulated turnover amounts that pass the verification process are then used to calculate the turnover amount for the a o current polling cycle or, in other worcis, the amount of turnover since the last 22/08 '00 TUE 16:51 FAZ B1 7 3229 3584 CLTLLEN & C0. f~JOl~

polling cycle. The turnover amount for the current polling cyGe is called the Actual Cycle Turnover (ATC).
After the ATC has been calculated, a percentage of the ATC is added to the jackpot amount (also known as the jackpot value). This s percentage is called the Jackpot Incn?ment Percentage and is a constant that is entered into the DMS 100 and then uploaded to the CJC 200. If there is more than one jackpot level, a percentage of the ATC is added to the jackpot amount of each jackpot level. The Jackpot Increment Percentage for each jackpot level may vary. The new jackpot amount is then stored in the CJC
200 and a CRC is built across the new jackpot amount.
The CJC 200 then determines whether to awarci the updated jackpot amount. This is done by generating a random number within the CJC
200 and comparing the random number with a predefined Jackpot Hit Value.
If the random number is equal to the Jackpot Hit Value this is classed as a is jackpot hit. If there is more than one jackpot level, a random number is drawn for each jackpot level and compared with a corresponding Jackpot Hit Value.
Before an additive random number generator RNG within the CJC 200 generates the random number, a range called the Jackpot Hit Range for the RNG is first determined. The Jackpot Hit Range is effectively 2o the chance of winning a jackpot during the polling cycle and is inversely proportional to the ATC during the poll. tn other worms, the higher the ATC
for a particular polling cycle, the smaller the Jackpot Hit Range and, hence, the greater the chance of the jackpot being awarded.
The Jackpot Hit Range for a particular polling cycle is calculated 25 as fOIIOWS:
Jackpot Hit Range = System Range x E~~~ Turnover Contributed Actual Turnover Contributed Where, the System Range and the Expected Turnover Contributed (ETC) are constants that are entered into the DMS 100 and then uploaded to the CJC
200. The System Range is a number that determines the overall (probable) so frequency that a particular jackpot level will be awarded at. For example, a 22/08 '00 TL1E 18:62 FAa 61 7 X229 X984 CULLEN & C0. ~I014 System Range of 100,000 for a particular jackpot level will result in that jackpot level being awarded twice as often compared to the case where the System Range is equal to 200,000. The ETC is an estimate of the amount of turnover that will be contributed to a particular jackpot level for each polling s cycle- The Actual Turnover Contributed (ATC) has been discussed previously.
With reference to Fig. 2, if there is no hit on the Jackpot Hit Value of any particular jackpot level, the CJC 200 waits until 6 seconds have elapsed from the commencement of the current polling cycle to commence a io new polling cycle in which the previously described process is repeated.
dig. 3 illustrates the instance where there is a hit on a Jackpot Hit Value of a particular jackpot level. In this case, if the ATC is greater than 0 (i.e. if there was turnover for the polling cycle), the CJC 200 then proceeds to pick the VJC 300 which will be awarded with the jackpot amount of the ~s jackpot level. If there was no turnover for the polling cycle (i.e. ATC is equal to 0) and there was a hit on a Jackpot Hit Value of a particular jackpot level, the jackpot hit is simply ignored and thrown away since no jackpot can be awarded if none of the EGMs 40 were being played during the poll.
In order to pick a winning VJC 300, the CJC 200 uses the ATC
2o as the range for the RNG. The RNG then generates a number which is called the Venue Hit Number. The cycle turnover of each VJC 300 (i.e. the turnover within the current polling cycle of each VJC 300), commencing with a first VJC 300, are then successively added together until the addition of the cycle turnover of a particular VJC 300 results in the Venue Hit Number being zs equalled or exceeded. The VJC 300 responsible for the Venue Hit Number being equalled or exceeded is the winning VJC 300. Thus, say for example, that there are three VJCs 300 and that the first VJC 300 has a cycle turnover of 9, the second VJC 300 has a cycle turnover of 3 and the third VJC 300 has a cycle turnover of 4. Therefore, the ATC is 16 and this number is used as a o the range for the RNG. The RNG then generates a Venue Hit Number 22/08 '00 TOTE 16:52 FAa 81 T 3229 3584 CLTLLEN & C0. ~ 015 between 0 and 16. if the generated Venue Hit Number is 10 (say) the CJC
200 then commences adding the cycle turnover of each VJC 300 starting with the first VJC 300. Thus, starting with 0, the cycle turnover of the first VJC

is added giving 9 which does not equal or exceed 10 (the Venue Hit Number) s so, the cycle turnover of the second VJC 300 is added which gives 12. Since the addition of the cycle turnover of the second VJC 300 resulted in the Venue Hit Number being exceeded, the second VJC 300 is the winning VJC
300. It should be noted that this method of selecting the winning VJC 300 results in the VJCs 300 with greater cycle contributions to the jackpot levels xo having a greater chance of winning.
Once all of the winning VJCs .300 of each winning jackpot level have been determined, the winning VJCs 300 are palled (see Fig. 3) by the CJC 200 to transmit the cycle turnover of each of their EGMs 40 starting with the VJC's 300 first EGM 40. The CJC 200 then runs a CRC over the received ~s cycle turnovers of the EGMs 40 and verifies it with the EGM CRC
verification number that was previously determined during the first part of the polling cycle. If this verification fails, the system 10 is shutdown because it indicates that the system 10 may possibly have been tampered with. If the verification passes, the CJC 200 then proceeds to determine the EGM 40 (or EGMs 40 in ao the case of more than one jackpot level having been won) which has won the jackpot level.
The selection of the winning EGM 40 is pertormed in the same way as the winning VJC 300 is selected. The cycle turnover of the winning VJC 300 is used as the range of the RNG. The RNG then generates an EGM
as Hit Number. The cycle turnover of each EGM 40 of the winning VJC 300 is then added (starting with the first EGM 40) and the EGM 40 that causes the EGM Hit Number to be equaled or e~cceeded is the winning EGM 40. Thus, for example, there might be three EGMs 40 with the first EGM 40 having a cycle tumov~r of 3, the second EGM 40 having a cycle turnover of 2 and the 3 o third EGM 4D having a cycle turnover of 2. The cycle turnover of the winning 22/08 '00 TtJE 18:52 FAa 61 7 x229 X584 CULLEN & C0. 1~J016 x9 VJC 300 is therefore squat to 7. The RNG then generates an EGM Hit Number between 0 and 7. Assume that the EGM Hit Number is 5 (say).
Now, starting with a value of 0, the cycle turnover of the first EGM 40 is added giving 3 which does not equal or exceed 5 (the EGM Hit Number) so, the s cycle turnover of the second EGM 40 is added which gives 5. Since the addition of the cycle turnover of the second EGM 40 resulted in the EGM Hit Number being equalled, the second EGM 40 is the winning EGM 40. This method of selecting the winning EGM 40 results in the EGMs 40 with greater contributions to the jackpot levels having a greater chance of winning.
io With reference to Fig. 3, once the winning EGM 40 (or EGMs 40 in the case of multiple jackpot levels being won) is detem~ined, the CJC 200 logs the win as being valid and the winning VJC 300 is notified of the win (about 7 seconds after the commencement of the cycle) followed by the other VJCs 300. Checks are made to ensure that each venue has received all is jackpot win information. The DMS 100 is also sent the win information.
If a winning VJC 300 fails to acknowledge to the CJC 200 during the jackpot alk~caHon process, the jackpot is deemed not to have occurred and a "re-pick" mode is in'ttiated. in the re-pick mode the CJC 200 will attempt during the next polling cycle tv allocate the jackpot. The whole procedure of zo choosing a winning venue, choosing a winning gaming machine and so on is repeated to ensure that the ja'akpot is not awarcJed to an inactive gaming machine.
In order to indicate to players the jackpot amount and/or that a jackpot has been won, each venue is provided with a display that is controNed 2s by a VJC 300. In the winning venue, the display indicates the winning EGM
40 and the winning jackpot amount. At non-winning venues, the winning .
jackpot amount and the name of the venue where the jacket was won will be displayed. The displays also indicate when a venue is offline to the CJC 20o.
The displays may also be provided with a means for audibly alerting the 3 o players when a jackpot has been won.

-.22/08 '00 TOTE 18:53 FAa 81 7 3229 3384 CULL,EN & C0. f~I017 is Next, the current jackpot amount for the awarded jackpot level is reset with a Jackpot Starting Amount, all other online VJCs 300 are notified of the award of the jackpot and then the next polling cycle is commenced. The Jackpot Starting Amount is a constant that is initially entered into the DMS
s 100 and then uploaded to the CJC 200.
As previously mentioned, the CJC 200 accepts a number of input parameters from the DMS 100 for each jackpot level. These input parameters dictate the operating characteristics of the respective jackpot levels. In summary, the input parameters that must be provided to the CJC
200 are the Jackpot Starting Amount, Jackpot Hit Range, Jackpot Increment Percentage and the Expected Turnover Contribution (ETCj. Each of the aforementioned parameters are interrelated and infiuenoe the characteristics of the jackpot level at any given time.
The various hardware components of the system 10 will now be discussed with reference to Figs. 4 to 15.
Fig. 4 is a block diagram of the VJC 300 located at a particular venue having a plurality of EGMs 40. 'fhe system 10 includes at least one venue with EGMs 40 although it is preferred that a plurality of venues each controlled by a VJC 300 and each having a plurality of EGMs 40 be present in 2 o the system 10.
