DETAILED DESCRIPTION

(5) The gaming system 100 illustrated in FIG. 1 is representative of a system that can be used in gaming establishments such as casinos. The gaming system 100 comprises several key elements including numerous slots machines 102a to 102d, a casino management system (cms) 104a and 104b, a data network 106, and a transfer server 108.

(6) In relation to the slot machines 102a to 102d, these are typical of slot machines manufactured and distributed by gaming companies such as International Game Technology (IGT) and Scientific Games. The slot machines 102a to 102d are typically arranged to offer patrons of the casino the ability to stake a wager on the outcome of a spinning reel game of chance. While this particular embodiment of the system 100 is described in the context of traditional slot machines, it is envisaged that in alternative embodiments different types of gambling machines can be incorporated. For example, alternative embodiments can include a mixture of conventional slot machines and other gambling machines such as video poker and/or bingo machines. The system 100 is only described in the context of traditional slot machines for simplicity.

(7) The casino management system 104a and 104b is typical of casino systems made available by gaming companies such as International Game Technology and Scientific Games. The casino management system 104a and 104b is operated by a casino and allows the casino to perform a range of operational function in conjunction with the slot machines 102a to 102d. For example, the casino management system 104a and 104b would perform all key accounting functions in relation to all money put through and paid out by the slot machines 102a to 102d. The casino management system 104a and 104b can also provide a range of other functionality such as providing promotional and bonus content to the slot machines 102a to 102d. Other functions that may be offered by the casino management system 104a and 104b is cashless (ticket in/ticket out) functionality and player card (loyalty) operations. As described in subsequent paragraphs of this description, the casino management system 104a and 104b has a unique function in relation to managing a digital currency.

(8) The transfer server 108 is a unique server and a detailed description of its functions are provided in subsequent paragraphs of this description. However, the high-level purpose of the transfer server 108 is to initiate a transfer of digital currency that may reside in any of the slot machines 102a to 102d to the casino management system 104a and 104b.

(9) The data network 106 is a data network that allows the slot machines 102a to 102d, the casino management system 104a and 104b and the transfer server 108 to exchange data with each other as required. The data network 106 is in the form of a high-speed Ethernet based network. As such, the slot machines 102a to 102d, casino management sever 104a and 104b and transfer server 108 are all coupled to the data network 106 via appropriate Ethernet interfaces. While the data network 106 is described as being an Ethernet based network it is envisaged that other suitable networking technologies could be employed in alternative embodiments. An example of an alternative networking technology is WiFi.

(10) As described previously, the system 100 includes certain functionality to support digital currency. More specifically, what makes the gaming system 100 unique over prior art gaming systems is that it allows users of the slot machines 102a to 102d to wager based on digital currency. In this particular gaming system 100 a user of any of the slot machines 102a to 102d can insert Bitcoins into a slot machine 102a to 102d in the same way a user can insert traditional government issued currency such as US dollars. It is envisaged that alternative embodiments digital currencies other than Bitcoin can be used with the slot machines 102a to 102d. Alternative digital currencies can include, for example, Zerocoin, Primecoin and Litecoin. In addition to accepting digital currency in the form of Bitcoins, the slot machines 102a to 102d will also accept traditional government issued currency therefor allowing the slot machines 102a to 102d to accept both government currency and digital currency.

(11) With the ever increasing popularity and widespread commercial acceptance of digital currencies, the gaming system's 100 support of digital currencies is to allow patrons of a casino to engage in gambling activities in much the same way that patrons currently gamble using government currencies. The following describes how the gaming system 100 enables patrons to gamble with the digital currency, Bitcoin.

(12) The first thing to note about the system 100 is that to enable wagering on the slot machines 102a to 102d using digital currency is that the slot machines 102a to 102d are arranged to allow a player to insert their digital currency. To do this it is not possible to use existing bill acceptorsinstead each slot machine 102a to 102d has a specific input arrangement for allowing players to insert their digital currency. In the case of digital currency in the form of Bitcoins each of the slot machines 102a to 102d are equipped with a USB port. By having USB ports on the slot machines 102a to 102d a player can safely store their Bitcoins on a USB stick (or other USB data storage device) and carry that USB stick to a casino. To load Bitcoins into a slot machine 102a to 102d for gambling a player inserts their USB stick (loaded with Bitcoins) into a slot machine 102a to 102d (step 210 of FIG. 2). Subsequent to detecting the insertion of the USB stick, the slot machine 102a to 102d transfers the Bitcoins on the USB stick into secure memory in the slot machine 102a to 102d (step 212 of FIG. 2).

(13) Once the slot machine 102a to 102d has transferred the Bitcoins from the USB stick into its internal secure memory, the slot machine 102a to 102d proceeds to transfer the Bitcoins to the casino's central digital currency wallet (step 214 of FIG. 2). In relation to the casino's central digital currency wallet, the casino management system 104a and 104b is augmented with a secure storage facility (such as a RAID) for securely storing Bitcoins received from the slot machines 102a to 102d. To transfer Bitcoins from slot machines 102a to 102d to the casino management system 104a and 104b, the slot machine 102a to 102d initiates a transfer of the Bitcoins by sending data (representing the Bitcoins) via the data network 106 to the casino management system 104a and 104b. On receiving the data that represents the Bitcoins the casino management system 104a and 104b stores the Bitcoins in the central currency wallet (step 216 of FIG. 2).

(14) Once the Bitcoins have been transferred between the slot machines 102a to 102d and the casino management system 104a and 104b (as described above), the casino management system 104a to 104b instructs the relevant slot machine 102a to 102d to put the relevant number of credits on the slot machine 102a to 102d (step 218 of FIG. 2). This process of the casino management system 104a to 104d applying credits to the slot machine 102a to 102d is essentially the same process that is currently employed for existing cashless gaming such as that based on ticket-in-ticket-out. Once the credits have been applied to the slot machine 102a to 102d the player is free to play the slot machine 102a to 102d as normal.

(15) As noted earlier, the system 100 comprises a transfer server 108. The server 108 is capable of initiating a transfer of Bitcoins from the slot machines 102a to 102d to the casino management server 104a and 104b. In the previously described example of transferring Bitcoins from the slot machines 102a to 102d to the casino management system 104a and 104b the transfer was initiated by the slot machine 102a to 102d, however it is possible that the initiation of the Bitcoin transfer is performed by the transfer server 108 and not the slot machines 102a to 102d. In this scenario, the transfer server 108 will interact with the slot machines 102a to 102d to cause the slot machines 102a to 102d to transfer bit coins to the casino management server 104a to 104b via the data network 106 (step 213 of FIG. 2).

(16) Because the slot machines 102a to 102d are designed to operate in licensed gaming venues it is mandatory that the slot machines 102a to 102d and the casino management server 104a and 104b cooperate to maintain detailed records of all money wagered and paid out (prizes) for auditing purposes. In this regard, the slot machines 102a to 102d and the casino management system 104a and 104b maintain detailed records of any Bitcoins inserted and wagered on the slot machines 102a to 102d.

(17) The system 100 is also arranged to allow players of the slot machines 102a to 102d to cash out in Bitcoins. To do this the player of a slot machine 102a to 102d hits the cashout button on the slot machine 102a to 102d (step 320 of FIG. 3). In response to this the slot machine 102a to 102d first gives the player an option to redeem their unplayed credit in the form of normal legal tender or digital currency (step 322 of FIG. 3). This option is presented to the player by displaying a selection menu on the screen of the slot machine 102a to 102d. By touching the relevant section of the slot machine 102a to 102d screen the player can make their selection of whether they want to receive the unused credit in normal legal tender or digital currency. If the player elects to receive unused credit in normal legal tender then the slot machines 102a to 102d issue the legal tender in the regular well known techniques (step 323 of FIG. 3). In the event the player of the slot machine 102a to 102d opts to take their unused credits in digital currency the next thing the slot machine 102a to 102d does is to notify the casino management system 104a and 104b that the player wants to redeem digital currency (step 324 of FIG. 3). In response to this the casino management system 104a and 104b retrieves the appropriate number of Bitcoins from its central wallet and sends them as data (representing the Bitcoins) via the data network 106 to the slot machines 102a to 102d (step 326 of FIG. 3). Subsequent to receiving the Bitcoins from the casino management system 104 the slot machine 102a to 102d then proceeds to dispense the Bitcoins to the player (step 328 of FIG. 3).

(18) To facilitate the dispensing of Bitcoins to the player, the player must have inserted their USB stick into the slot machine 102a to 102d (as previously described). When inserted, the slot machine 102a to 102d transfers the relevant Bitcoins to the player's USB stick via the USB port. At this point the player can remove their USB stick from the USB port of the slot machines 102 and is free to take with them their redeemed Bitcoins.
