A system for presenting a skill-based game. The system includes at least one server having a processor configured to execute machine-readable code. The processor is configured to cause the server to create and provide a set of 3D advanced choice game to the plurality of presentation devices of the users, which each present the set of 3D advanced choice games on a respective display. Each game of the set having an assigned fixed odds payout based on winning user selections. The server receives, over the wide area network, data from the presentation devices characterizing a set of user-selected winners of the 3D advanced choice games made by the users. The server update the event data pertinent to participants in the actual events associated with the 3D advanced choice games. The server uses the updated data to calculate and assign payoffs to the users based on the fixed payoff odds.

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.

An embodiment may involve receiving, at a receiving component, an instruction; determining, by way of a random number generator (RNG), a set of symbols and a sync symbol; displaying, on a display component, the set of symbols in a two-dimensional array and the sync symbol in a preview space; and while there are pre-determined patterns of symbols in the two-dimensional array: replacing the pre-determined patterns of symbols in the two-dimensional array with vacant symbol positions; determining, by way of random selection by the RNG, whether replacement symbols to be placed in the vacant symbol positions are subject to synchronization, wherein the replacement symbols being subject to synchronization causes each of the vacant symbol positions to be filled with the sync symbol, and wherein the replacement symbols not being subject to synchronization causes each of the vacant symbol positions to be filled with further symbols determined by way of the RNG.

There is provided a gaming system, gaming machine, and method that utilize an electronic display device configured to display a plurality of symbol-bearing reels and an array. The reels bear standard symbols, transformable symbols, and a catalyst symbol. Based on a wager tier to which a player's wager belongs, one or more of the transformable symbols are transformed into value-bearing symbols or the catalyst symbol. The reels are then spun and stopped to land symbols in the array. In response to the landed symbols including a catalyst symbol, a payout is awarded based upon values on any value-bearing symbols among the landed symbols.

A gaming machine provides a spinning reel game having a base game, from which a hold and spin feature game may be triggered when a determined number of configurable symbols are displayed in a base game outcome. When the feature game is triggered, the configurable symbols may be held in place. The player may be provided one or more spins during the feature game in which to collect additional configurable symbols. Any additional configurable symbols may be retained on the display during subsequent spins until the feature game is completed. A trigger symbol, which may or may not be a configurable symbol, may cause reel expansion. The reel expansion may involve adding a row or a column. In some examples, the trigger symbol also may alter the value of at least some configurable symbols. For example, the trigger symbol may cause the value of a configurable symbol to increment.

A method comprises initiating a gaming session for a grid-based game, tracking a number of consecutive losing plays of the grid-based game during the gaming session, and providing a player of the grid-based game with an option to reuse a wild symbol that appears in one play of the number of consecutive losing plays in a next play when the number of consecutive losing plays exceeds a threshold. The method further comprises receiving first input from the player to reuse the wild symbol in the next play, generating, in response to the first input, a sequence of symbols comprising the wild symbol, and causing a display to display the sequence of symbols populated in the array of cells.

The present disclosure relates generally to systems and methods for providing sliding symbol operations in grid-base games. The sliding symbol operations allow a player of the gaming device to move, by sliding or dragging, a particular symbol from one cell to another in an array of cells between plays of the grid-based game. Movement of the particular symbol from one cell to another allows a player to control their chances of winning and alter the proposed payouts for winning sequences of symbols for at least one subsequent play of the grid-based game.

Some implementations may involve presenting a feature game round that includes a hold and spin stage and a free game stage. The free game stage may be presented after the hold and spin stage. In some examples, the number of free game instances may correspond to the number of configurable symbols accumulated by the conclusion of the hold and spin stage. In some instances, at least one of the configurable symbols accumulated by the conclusion of the hold and spin stage may indicate a modifier for the free game stage. The modifier may correspond with a modification of one or more reels that are used during a free game instance. In some examples, at least one of the configurable symbols accumulated during the hold and spin stage may indicate a multiplier for an award that is determined during a first free game instance.

Systems and techniques for providing time-based sticky wild features for use in multiplayer gaming tournaments are disclosed, including various mechanisms and techniques for distributing sticky wild patterns for use in provisioning such sticky wild features.

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.
