A gaming system is disclosed that comprises a symbol selector configured to select a plurality of symbols from a set of symbols for display in a respective plurality of display positions in a display area, the set of symbols including a plurality of defined special symbols, and a special symbol determiner configured to determine whether at least two special symbols are displayed adjacent each other. The gaming system is configured to hold special symbols determined to be displayed adjacent each other at respective display positions for at least one subsequent selection of symbols. The gaming system further comprises an outcome evaluator configured to determine a game outcome based on the displayed symbols including the displayed held special symbols.

The present disclosure relates broadly to a gaming device operable under control of a processor together with a method of operating a gaming device. The disclosure relates particularly, although not exclusively, to a gaming device and method where a wild symbol is in the course of a plurality of games extends along at least one of a plurality of symbol reels.

An electronic gaming machine and method having independently operable game display windows comprising independent displays and controls to play a game individually or as a group game between or among players. The electronic gaming machine comprises a video display and a game controller configured to display on the video display a first set of reels and a second set of reels, control the video display to initially synchronously spin pairs of first and second reels to a stop, and, upon a potential trigger condition being met, control the video display to asynchronously spin pairs of first and second reels to a stop. The game controller is further configured to control the video display to move a special symbol on the video display in a direction opposite to an evaluation direction towards an evaluated position.

A gaming machine provides a spinning reel game having a base game, from which a hold-and-spin game is triggered when a determined quantity of configurable symbols are displayed in a base game outcome. For each spin of the feature game, spin tags of configurable symbols are updated. When the spin tags have a predetermined relationship to a threshold value, the associated configurable symbol is split into a group of symbols. A feature game award is presented based on values associated with each configurable symbol in the feature game outcome.

A column and row matrix of play positions each having an open state and locked state, the open state for display of a random game symbol received during play of a game and the locked state for holding a game symbol having an award, for creating a win row or win column of award game symbols during sequential plays of the game, which game symbols in the win row after award are removed and award game symbols vertically higher in the matrix cascade to a lower play position having an open state for re-arranging the matrix for subsequent play of the game. A method of re-arranging a matrix game for play is disclosed.

Innovations in integrating a skill-based selection mechanism and a random number generator (“RNG”)-event-based mechanism in an electronic gaming device are described. For example, some of the innovations relate to integrating a skill-based selection mechanism and an RNG-event-based mechanism in an electronic gaming device that uses one or more sets of matrix elements and one or more sets of user-selectable action elements. User-selectable action elements are determined using RNG events. Matrix elements for a symbol matrix are also determined using RNG events. The action elements can be selectively applied, according to user input provided by a user, to change matrix elements (e.g., to “re-spin” one or more matrix elements, or to convert one or more matrix elements from one type to another type).

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.

An electronic gaming machine, system, and method are disclosed for conducting a keno game. The keno game may be conducted alone or in conjunction with a bingo game. The electronic gaming machine may receive a wager from a player, and conduct the bingo game and/or keno game in response to the wager. Based on the wager, a quantity of numbered keno balls may be designated as feature numbered keno balls. The electronic gaming machine may conduct the keno game using the feature numbered keno balls, and display a bonus if and/or when one or more feature numbered keno balls match one or more player selected keno numbers.

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.
