BACKGROUND

Casino gaming machines are subjected to rigorous regulation in a typical gaming jurisdiction. These regulations are designed to eliminate or at the very least reduce fraud or cheating, both of the games and of the public. For example, these regulations may require that the software for a gaming machine is carefully controlled such that there is little or no possibility that it can be tampered with between the time it is burned or copied into the storage medium and the time it is fetched by a gaming machine for use in controlling the operation of the machine. For instance, regulations may require that the gaming software be copied onto the storage medium in a secure environment and brought to and installed in the target gaming machine in a secure fashion. Thus, updated gaming software may have to be written to a tamper proof read only memory device within the confines of a secure facility, and taken under lock and key to a gaming machine to be installed by authorized personnel only. Further, there is typically a mechanism or process by which gaming authorities can test to see that the software installed in a particular gaming machine has been approved by gaming regulators, and is not an unauthorized version. Thus, updating gaming software, for example, to correct a bug or to provide an enhanced, modified or new gaming experience to a user, can be burdensome.

Other problems faced in connection with gaming machine technology is the need to handle failures of software or hardware in a gaming machine. If a player has credits on a machine, and the machine fails during play, the player's credits may be “lost” in that the software registering the credits may crash or the memory storing the credit information may fail. These types of failures are to be avoided as much as possible both because of the inconvenience and losses suffered by the affected player but also due to the potential for fraudulently induced failures that may be used to steal money from a player.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the inventive subject matter can be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention. The leading digit(s) of reference numbers appearing in the Figures generally corresponds to the Figure number in which that component is first introduced, such that the same reference number is used throughout to refer to an identical component which appears in multiple Figures. Signals and connections may be referred to by the same reference number or label, and the actual meaning will be clear from its use in the context of the description.

FIG. 1 is a perspective view of a wagering game machine, according to exemplary embodiments of the inventive subject matter disclosed herein. As shown in FIG. 1, the wagering game machine 100 can be a computerized slot machine having the controls, displays, and features of a conventional slot machine. The wagering game machine 100 can be operated while players are standing or seated. Additionally, the wagering game machine 100 is preferably mounted on a stand (not shown). However, it should be appreciated that the wagering game machine 100 can be constructed as a pub-style tabletop game (not shown), which a player can operate while sitting. Furthermore, the wagering game machine 100 can be constructed with varying cabinet and display designs. The wagering game machine 100 can incorporate any primary game such as slots, poker, or keno, and additional bonus round games. The symbols and indicia used on and in the wagering game machine 100 can take mechanical, electrical, or video form.

As illustrated in FIG. 1, the wagering game machine 100 includes a coin slot 102 and bill acceptor 124. Players can place coins in the coin slot 102 and paper money or ticket vouchers in the bill acceptor 124. Other devices can be used for accepting payment. For example, credit/debit card readers/validators can be used for accepting payment. Additionally, the wagering game machine 100 can perform electronic funds transfers and financial transfers to procure monies from financial accounts. When a player inserts money in the wagering game machine 100, a number of credits corresponding to the amount deposited are shown in a credit display 106. After depositing the appropriate amount of money, a player can begin playing the game by pushing play button 108. The play button 108 can be any play activator used for starting a wagering game or sequence of events in the wagering game machine 100.

As shown in FIG. 1, the wagering game machine 100 also includes a bet display 112 and a “bet one” button 116. The player places a bet by pushing the bet one button 116. The player can increase the bet by one credit each time the player pushes the bet one button 116. When the player pushes the bet one button 116, the number of credits shown in the credit display 106 decreases by one credit, while the number of credits shown in the bet display 112 increases by one credit.

A player may “cash out” by pressing a cash out button 118. When a player cashes out, the wagering game machine 100 dispenses a voucher or currency corresponding to the number of remaining credits. The wagering game machine 100 may employ other payout mechanisms such as credit slips (which are redeemable by a cashier) or electronically recordable cards (which track player credits), or electronic funds transfer.

The wagering game machine may also include a primary display unit 104 and a secondary display unit 110 (also known as a “top box”). The wagering game machine may also include an auxiliary video display 130. In one embodiment, the primary display unit 104 displays a plurality of video reels 120. According to embodiments of the invention, the display units 104 and 110 can include any visual representation or exhibition, including moving physical objects (e.g., mechanical reels and wheels), dynamic lighting, and video images. In one embodiment, each reel 120 includes a plurality of symbols such as bells, hearts, fruits, numbers, letters, bars or other images, which correspond to a theme associated with the wagering game machine 100. Furthermore, as shown in FIG. 1, the wagering game machine 100 includes an audio presentation unit 128. The audio presentation unit 128 can include audio speakers or other suitable sound projection devices.
