Abstract: There is disclosed a method of playing a game dependent on two parameters of a contest. The game is played by a game controller setting a value of a first parameter prior to commencement of the contest. A player then selects an identifier from a set of identifiers corresponding to all possible values of the second parameter. The value of said second parameter is determined when said first parameter reaches said set value. The identifier from said set of identifiers corresponding to said determined value of said second parameter is then determined and a win is awarded to a player if the player's identifier corresponds to the determined identifier.
