  • Publication number: 20260018027
    Abstract: An electronic gaming device includes a display device and a processor configured to execute instructions stored in a memory device. When executed, the instructions cause the processor to at least initiate a primary bonus game in response to a free play trigger condition being satisfied during a base game and determine a number of free spins of a plurality of reels for use during the primary bonus game. The instructions further cause the processor to control the display device to simulate spinning and stopping the plurality of reels in conjunction with sequentially counting up from an initial numerical indicium to a final numerical indicium in association with spinning the plurality of reels according to the determined number of free spins and initiate a secondary bonus game that includes a free spin count-down from the final numerical indicium to the initial numerical indicium.

  • Publication number: 20260011215
    Abstract: An electronic gaming system is provided. The electronic gaming system includes a game controller in communication with a display device. The game controller controls the display device to display a base reel game, determine that a base reel game outcome triggers a bonus wheel game, and control the display device to display the bonus wheel game. Displaying the bonus wheel game includes displaying a wheel feature including a plurality of wedges, where each wedge depicts a credit value or an action feature and displaying pointer(s) configured to identify one of the plurality of wedges. Displaying the bonus wheel game also includes controlling at least one of the wheel feature or the at least one pointer to rotate and subsequently stop to determine a bonus wheel game outcome. The bonus wheel game outcome includes the credit value and/or the action feature depicted on the wedge(s) identified by the pointer(s).

  • Publication number: 20250378740
    Abstract: A gaming system includes a processor and a memory storing instructions thereon, wherein the instructions cause the processor to cause display of a spinning of a bonus indicator relative to a stopping position indicator, the bonus indicator including a plurality of outcome sections each including an outcome indicator displayed therein. The instructions further cause the processor to stop the spinning of the bonus indicator relative to the stopping position indicator, the stopping position indicator identifying a first outcome section of the plurality of outcome sections when spinning of the bonus indicator is stopped and cause display of a moving of the stopping position indicator on the bonus indicator from the first outcome section to a second outcome section of the plurality of outcome sections.

  • Publication number: 20250349172
    Abstract: Disclosed are video slot games, including Class II and III gaming machines and systems, comprising a five reel video (5RV) arrangement that includes metamorphic symbols that incrementally expand, enlarge, balloon, widen, lengthen, or grow, e.g., when the metamorphic symbol lands on a predetermined position, or a winning payline, and that communicate the effect to the player of the incremental growth or increase in size by providing an enhanced user interface with information about the player's progress toward a potential special awards or status. The metamorphic symbols may incrementally expand, enlarge, balloon, widen, lengthen, or grow with each successive winning land, and may, in some examples, ultimately snap, crack, pop, deflate, or explode, while optionally deforming adjacent presentations to provide various award enhancements.

  • Patent number: 12367742
    Abstract: A free spin count-up bonus game and a subsequent banked free spin count-down secondary bonus game are described herein. The free spin count-up game may be triggered during play of a base game. A numerical indicium may be provided. During the free spin count-up bonus game, the indicium may count up from an initial value to a final value. When the indicium reaches a maximum or final value, the value may be regarded as indicating a number of “banked” free spins. The number of banked free spins may be compared to one or more threshold values. If the number of banked dree spins is greater than or equal to one or more threshold values and there is a successful outcome on a random determination, a secondary bonus game may be initiated, during which the indicium is decremented from the final value back down toward the initial value.

  • Publication number: 20250205590
    Abstract: Embodiments of the disclosure provide an electronic gaming machine, systems and methods with a wheel feature mode dependent on base game outcomes. Specifically, a gaming machine comprises a user interface, a display device, and a game controller. The wheel feature mode is triggered during a base game based on wheel feature mode trigger conditions. The wheel feature mode animates a graphical user interface to present a spinning feature wheel that provides credit value awards, dependent on base game outcomes (e.g., one or more base game bingo pattern outcomes), through a sequence of player-initiated feature wheel spins. If one or more winning base game outcomes remain in the base game, the wheel feature mode continues with each wheel slice value reset, such that the minimum wheel slice value is equal to or greater than the previous spinning feature wheel credit value award which continues until no winning base game outcomes remain.

  • Publication number: 20250140070
    Abstract: An electronic gaming system is provided. The electronic gaming system may be configured to, in response to receiving a user input, determine that at least one winning pattern is included on a base game bingo card by electronically comparing a base game ball call to the base game bingo card, cause a base game reel outcome to be displayed on a display including a set of reels, the base game reel outcome corresponding to the at least one winning pattern, determine that a feature game is triggered, in response to the feature game being triggered, and determine that at least one new winning pattern is included (i) on a new bingo card by electronically evaluating the new bingo card using the base game ball call or (ii) on the base game bingo card by electronically evaluating the base game bingo card using a new ball call.

  • Publication number: 20250104516
    Abstract: An electronic gaming system including a memory and a processor is described. The processor is configured to cause display of a plurality of symbol positions for an electronic game and receive a first player selection of a first symbol position. The processor is also configured to reveal a first symbol at the first symbol position in response to the first player selection wherein the first symbol is associated with a first output amount and receive a second player selection of a second symbol position. The processor is also configured to, in response to the second player selection, apply a first multiplier associated with the second symbol position to the first output amount to generate a multiplied first output amount and reveal a second symbol at the second symbol position wherein the second symbol is associated with a second output amount.
