  • Publication number: 20090258693
    Abstract: The instant invention provides a method for determining by a first game (which may or may not be displayed to the player) a game outcome which is displayed to the player at least via a different second game representation, across a number of gaming machines where preferably all games being mapped are equivalent to permit a one to one correspondence in terms of prizes awardable. The method requires at least 2 lists of symbols with the first list (for example having a list of 6 sided die combinations) varying in order for each gaming machines, and the second list being a common list of game outcomes used on each gaming machine. For each combination in the first list, an index is used to point to a corresponding combination in the second list. By doing so, the first list upon receiving a dice combination acts as a filter to redirect which game outcome of the second list should be shown, thereby allowing games to use the same random numbers to show different game outcomes.
