Abstract: A gaming system includes a credit mechanism configured to receive credit input by a player for contribution to a credit balance and a display configured to display a plurality of standard symbol positions and optionally one or more additional symbol positions. The system also includes a betting module configured to determine a bet amount and game play instructions on commencement of a game input using a player interface, the bet subtracted from the credit balance. A symbol selector selects symbols for display in the plurality of standard symbol positions and, dependent on the amount wagered, further arranged to select and display symbols in the additional symbol position(s) to increase the probability of a win outcome being generated. An outcome determiner determines an outcome of the game based on the displayed symbol positions.

Abstract: A method of awarding an award on a gaming machine, the method comprising: a) in a random selection process selecting an eligibility criterion or eligibility criteria from a plurality of possible eligibility criteria, whereby the selected criterion or criteria is deemed an active award trigger event; b) monitoring game play activity on the gaming machine for occurrence of the active award trigger event; c) when the active award trigger event occurs as a result of game play activity on the gaming machine, awarding the award; and d) following the completion of step c), or following the occurrence of another event: i) deeming the selected eligibility criterion or criteria an inactive award trigger event; and ii) repeating steps a) to c).

Abstract: In a gaming system, an initial set of symbols comprise symbols of a plurality of groups and are displayed in respective ones of display positions. A revised set of symbols is formed by modifying the display position of symbols of at least one of the groups that are formed. In one example, each group of symbols is selected from a set representing a reel of symbols. The reel of symbols is provided in a given order drawn on a physical looped reel. One or more symbols from each reel may be selected for display in accordance with a symbol selection algorithm. A game outcome may be determined based on the relative position of symbols within the revised set.
