Abstract: Machines and methods are described for displaying a predetermined symbol and a set of symbols selected from a global symbol set. A first symbol position can be randomly selected for displaying the predetermined symbol, which can include a multiplier meter to display a multiplier value randomly selectable from multiple multiplier values. A second symbol position can be randomly selected for displaying the predetermined symbol after moving along a path from the first symbol position. The predetermined symbol can be displayed as part of a predetermined number of outcome events earned upon determination that a trigger event occurred. A server machine can select symbol positions, multiplier values and symbol sets and provide data indicating the symbol positions, multiplier values and symbol sets to a client machine. The client machine can include a display to display the symbol sets, and multiplier values within a predetermined symbol.

The embodiment may also involve: selecting a first set of symbols associated with respective positions of each of the reels; determining that the first set of symbols includes exactly one or exactly two trigger symbols; locking in place all instances of the trigger symbols; selecting a second set of symbols associated with the respective positions of each of the reels, where the second set of symbols includes the locked-in-place trigger symbols; determining that the second set of symbols includes at least three trigger symbols; and providing an additional spin of the reels to the client machine, and unlocking all locked-in-place in place trigger symbols.

Abstract: An embodiment may involve a software application executed on behalf of a client machine with a graphical display unit, the software application graphically displaying animations that simulate spinning a plurality of reels. The embodiment may involve determining that a trigger event occurred, and determining a number of spins of the reels, where a multiplier is set to an initial value. The embodiment may involve carrying out iterations of operations comprising: selecting a set of symbols associated with positions of each of the reels, where the multiplier is increased in response to any non-winning outcome, and the multiplier is reset to the initial value in response to a winning outcome; and causing the graphical display unit to display an animation that simulates a spin of the reels that results in displaying the set of symbols, and the win multiplier increasing when a non-winning outcome appears in the set of symbols.

Abstract: Machines and methods are described for displaying a particular symbol at a corresponding symbol position for multiple consecutive outcome events, such as outcome events including a wager game played on a stand-alone machine located within a casino or a machine within a client-server architecture. After displaying the particular symbol for a first outcome event, the particular symbol can be displayed at the same symbol position within a symbol-display-portion for one or more successive outcome events without the particular symbol being selected to be displayed at the same symbol position. Other symbols displayed within the symbol-display-portion for the first and successive outcome events can be determined or selected by a processor using a random selection process. The particular symbol can be a Wild symbol. A data structure can include data for tracking whether the particular symbol is locked down for an outcome event after the first outcome event.
