Abstract: A gaming machine includes display means and a user interface to receive input in relation to displayed images, and a game controller configured to control images of symbols displayed on the display means and to play a primary game of chance. The game of chance includes emulating spinning and randomly stopping virtual reels to display an image of symbols in a matrix of symbol positions. The game controller determines a trigger event during the play of the primary game of chance, the trigger event including trigger event symbols composed of a predetermined number and a type of symbol, and in response to the trigger event, to reconfigure at least a subset of the matrix of symbol positions from the randomly stopped virtual reels, said subset excluding said trigger event symbols, the reconfigured subset of symbols defining a second screen feature which is distinct from the primary game of chance.

Abstract: An example gaming system is disclosed that includes a selector arranged to select a plurality of symbols from a set of symbols for display in a plurality of display position groups, with each display position group including a plurality of display positions. The example system includes an outcome evaluator arranged to determine whether the displayed symbols define a special winning symbol combination, the special winning symbol combination including a symbol from each of the display position groups. The example system also includes a prize allocator arranged to allocate a prize when a special winning symbol combination is displayed. The example system is arranged to progressively replace all symbols in each display position group with a replacement symbol corresponding to a symbol of the special winning symbol combination until the displayed symbols define the special winning symbol combination. A corresponding example method is also disclosed.

Abstract: A method of gaming comprising displaying a region comprising a plurality of symbol display positions on an electronic display, each symbol display position occupiable by one symbol at a time and being adjacent to at least one other symbol display position such that any movement of the symbols within the region involves a movement to an adjacent display position; populating at least part of the region by injecting symbols into the region at respective selected entry points of a plurality of possible entry points to the region in a respective direction of entry, each entry point corresponding to one of the symbol display; and evaluating the populated region to determine whether to make an award upon an evaluation condition being met.
