However, it should be understood that the invention is not limited to that particular field of use and may be suitable for other applications, such as gaming facilitated by the internet.
- Gaming machines have long been known and are now one of the most common forms of gambling. Usually gaming machines simulate a well-known game of chance. One of the oldest and best known forms of gaming machine is the rotating reel type “poker machine”. In light of its popularity, the present invention will be described with reference to this type of gaming machine. However, it will be appreciated that the invention is equally applicable to gaming machines other than the rotating reel type.
- Traditional poker machines use a series of three or more reels, each reel having symbols on its peripheral edge.
- the reels are rotated upon the placement of a bet and then stopped to produce an arrangement of randomly selected symbols. Winnings are paid if the random selection of symbols matches one of the predetermined winning combinations.
- these gaming machines have been computerised with a video screen replacing the physically rotating reels.
- the display screen typically presents an array of symbols and five columns and three rows equating to the symbols that would normally be seen on the five physically rotating reels of an old-style mechanical machine.
- Gaming machines can “pay winnings” in a variety of ways. These include dispensing money, dispensing tokens that can be redeemed for money, or simply adding credits to a credit meter that can be used for placing future bets or redeemed as money. Given the predominance of computerised gaming machines, winnings are most commonly paid in the form of credits tallied on a credit meter. However, those skilled in the art will readily understand that the term encompasses other payment mechanisms.
- Computerised machines have allowed players to simultaneously bet on the combination of symbols appearing in many different parts of the array. These parts of the array are referred to as “paylines” and consist of lines of adjacent symbols extending through the array. The symbols may be laterally or diagonally adjacent each other so that the paylines can extend along each row and various angled or “zigzag” lines through the array. Most computerised gaming machines will offer at least five paylines in a five-reel array, which makes the gaming experience significantly more exciting than the old-style mechanical machines which traditionally had a single payline through the middle row of symbols.

Description
- The present invention relates to gaming machines. The invention has been developed primarily in relation to computerised gaming machines and will be described herein with reference to that application. However, it should be understood that the invention is not limited to that particular field of use and may be suitable for other applications, such as gaming facilitated by the internet.
- Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
- Gaming machines have long been known and are now one of the most common forms of gambling. Usually gaming machines simulate a well-known game of chance. One of the oldest and best known forms of gaming machine is the rotating reel type “poker machine”. In light of its popularity, the present invention will be described with reference to this type of gaming machine. However, it will be appreciated that the invention is equally applicable to gaming machines other than the rotating reel type.
- Traditional poker machines use a series of three or more reels, each reel having symbols on its peripheral edge. The reels are rotated upon the placement of a bet and then stopped to produce an arrangement of randomly selected symbols. Winnings are paid if the random selection of symbols matches one of the predetermined winning combinations. More recently, these gaming machines have been computerised with a video screen replacing the physically rotating reels. The display screen typically presents an array of symbols and five columns and three rows equating to the symbols that would normally be seen on the five physically rotating reels of an old-style mechanical machine.
- Gaming machines can “pay winnings” in a variety of ways. These include dispensing money, dispensing tokens that can be redeemed for money, or simply adding credits to a credit meter that can be used for placing future bets or redeemed as money. Given the predominance of computerised gaming machines, winnings are most commonly paid in the form of credits tallied on a credit meter. However, those skilled in the art will readily understand that the term encompasses other payment mechanisms.
- Computerised machines have allowed players to simultaneously bet on the combination of symbols appearing in many different parts of the array. These parts of the array are referred to as “paylines” and consist of lines of adjacent symbols extending through the array. The symbols may be laterally or diagonally adjacent each other so that the paylines can extend along each row and various angled or “zigzag” lines through the array. Most computerised gaming machines will offer at least five paylines in a five-reel array, which makes the gaming experience significantly more exciting than the old-style mechanical machines which traditionally had a single payline through the middle row of symbols.
- Eventually, machines offered all the practical paylines in the five-column three-row array. Players come to expect machines to offer multiple paylines and game designers were forced to incorporate additional aspects of interest in order to attract players.
- As part of this ongoing effort to maintain player interest, many machines now offer secondary or “feature” games. The feature appears upon some trigger event such as predetermined outcome in a primary or “base” game. The feature can be used to provide the player with relatively large winnings and thereby provides a strong incentive to continue playing the machine. As various different types of feature have been devised, several have proven to be particularly effective and popular. Different versions are incorporated into many of the machines available today.
- One disadvantage associated with gaming machines which have feature games is that triggering the feature game may require many attempts. Consequently, a player may expend a significant amount of time and money before triggering the feature game. Furthermore, if a player cannot trigger the feature in a reasonable amount of time this may result in the player becoming frustrated or disinterested.
