Abstract: Electronic gaming machines and systems are disclosed that provide for a symbol-based main game that features an array of symbol positions that may, if an array growth condition is met, increase in size. Determining whether the array growth condition is met may involve determining how many array growth symbols are shown in association with a game play. A further determination may be made as to whether a feature game trigger condition is met and, if so, a feature game may be presented that utilizes the same array of symbol positions that were present in the main game when the feature game was triggered. Additional array growth may occur in the feature game if the array growth condition is met again.

Abstract: In one aspect, an electronic gaming system is described. The electronic gaming system includes a display device, a random number generator (RNG), a player input interface, and a game controller configured to execute instructions stored in a tangible, non-transitory, computer-readable medium. When executed by the game controller, the instructions cause the game controller to at least determine, during play of a base game, that an enhancement trigger condition is satisfied and convert the symbol displayed on each position having one of the first frame and the second frame displayed thereon into a wild symbol. The instructions further cause the game controller to determine that a bonus game trigger condition is satisfied and convert a plurality of positions on each reel with at least one position having the second frame displayed thereon, into a bonus reel. The instructions also cause the game controller to generate a bonus game outcome.

Abstract: Techniques and systems for providing games of chance with multiple levels of persistent features are disclosed. Some example systems include scatter prize indicators that are each associated with different symbol positions of a game of chance. When a scatter symbol is selected for a given symbol position, the scatter prize indicator associated therewith may be upgraded; selection of a sufficient number of symbol positions may result in a feature game mode being activated. During feature game mode play, scatter symbols are retained after each play of the game until either sufficient consecutive plays occur without any scatter symbols being obtained or until all symbol positions have scatter symbols. In the latter case, the scatter prize indicators are upgraded and play continues. In the former case, the feature game mode concludes. Various enhancements may be triggered based on the number of times that the feature game mode has been activated.

Abstract: A gaming device is provided. The gaming device is configured to determine that at least a threshold number of scatter symbols is displayed in respective slot positions of a plurality of reels, determine a number of free spin credits for a free spin feature, for each of the plurality of reels, cause the game display to increment a collection indicator corresponding to each reel by a number of scatter symbols displayed in the corresponding reel, generate at least one collectible symbols in one of the slot position, cause the game display to increment the collection indicator for the reels in which the collection symbols are displayed, determine that one of the collection indicators has reached a threshold number of collectible symbols, and cause the game display to display a reel replacement feature in the reel corresponding to the one of the collection indicators.

Abstract: Nested frenzy modes for games of chance are disclosed. When a first frenzy mode is activated, opportunities are provided to obtain first frenzy item symbols as part of game outcomes. Each first frenzy item symbol that is obtained in an outcome may cause a number of obtained frenzy items of a featured set of frenzy items to be incremented by a first value. When all frenzy items in the featured set of frenzy items are obtained, a featured set prize is awarded and a new set of frenzy items presented. Additionally, there are opportunities within the first frenzy mode to trigger a second frenzy mode in which second frenzy item symbols are potentially obtainable. Should a second frenzy item symbol be obtained, then the number of obtained frenzy items of the featured set of frenzy items may be incremented by a second value that is greater than the first value.

Abstract: An electronic gaming machine (EGM) or another type of gaming device may be configured to provide games that involve “WYSIWYG” (what you see is what you get) symbols or “prize on” symbols. The gaming device may be configured to provide the value of all “prize on” symbols that land during a single instance of a game if a prize on trigger symbol, which also may be referred to herein as a blast symbol, lands during the same instance of the game. In some examples, the game may be a base game. According to some examples, a feature does not need to be triggered during the instance of the base game for the value of all prize on symbols that land during the instance of the base game to be awarded. In other examples, the game may be a feature game, such as a “hold and spin” game.

Abstract: A method for providing a persistent feature in an electronic game includes: (A) simulates spinning of a plurality of reels; (B) generating a first spin result; (C) triggering a value feature based on the occurrence of at least one feature symbol appearing on the first reel and at least one feature symbol appearing on the second reel in first spin result, causing the electronic game to award value feature symbols that appear on the other reels; (D) during a second spin, displaying an animation of moving the first and second feature symbols one or more positions of the reel upon; (E) overlaying the moved feature symbols during the second spin of the plurality of reels; and (F) triggering the value feature for the second spin when at least one feature symbol appears on both the first reel and on the second reel.

Abstract: Game features for at least a base slot game may be selectable according to player input. According to some examples, game features may be selectable without exiting from a graphical user interface used to present the slot game. A first GUI portion may be presented in a first area of a display system. The first GUI portion may include display symbols for presenting the slot game. A second GUI portion may be presented in a second area of the display system while the first GUI portion is being presented in the first area, e.g., while the slot game is being presented in the first area. The second GUI portion may include multiple game feature images. Each game feature image may correspond with a selectable game feature.

Abstract: Some implementations may involve providing a slot game in which the game outcome presentation may involve displaying a persistent moving symbol. In some examples, an initial persistent moving symbol position may be based, at least in part, on a first bet level. Determining a game outcome may involve determining whether a persistent moving symbol position is a prize-triggering persistent moving symbol position. If an initial persistent moving symbol position is not a prize-triggering persistent moving symbol position, a persistent moving symbol may be presented in a secondary persistent moving symbol position of a next game outcome. The secondary persistent moving symbol position may be closer to the prize-triggering persistent moving symbol position than the initial persistent moving symbol position.
