Controlling an electronic gaming machine to provide a prize on symbol trigger
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.
1. An electronic gaming machine, comprising:
a display system including one or more displays;
an interface system including one or more user interfaces; and
a control system including one or more processors, the control system being configured for:
determining, for a game outcome for an instance of a game, which symbols will be presented on the display system by selecting the symbols to be presented from a symbol set that includes prize on symbols and at least one prize on trigger symbol, each prize on symbol including an indication of an award corresponding to the prize on symbol, a combined value of prize on symbols being payable at a conclusion of a feature game round;
controlling the display system to present first visual effects corresponding to the game outcome, the first visual effects including moving symbols and landing of one or more prize on symbols;
determining an award corresponding to the game outcome, wherein determining the award involves:
for a game outcome in which the control system determines that the game outcome includes a prize on trigger symbol, determining that the award includes a combined value of the one or more prize on symbols; and
for a game outcome in which the control system determines that the game outcome does not include the prize on trigger symbol, determining that the award does not include the combined value of the one or more prize on symbols; and
controlling the display system to present second visual effects corresponding to the award.
2. The electronic gaming machine of claim 1 , wherein the prize on symbols indicate one or more of a number of game credits, a number of currency units, an award multiplier or a progressive award.
3. The electronic gaming machine of claim 1 , wherein:
the game is a base game;
the control system determines that at least T prize on symbols land during the instance of the base game, T corresponding to a threshold number of prize on symbols required to trigger a feature; and
the control system is configured for controlling the display system to present the feature after controlling the display system to present second visual effects corresponding to the award.
4. The electronic gaming machine of claim 3 , wherein the feature comprises one or more “hold and spin” bonus games and wherein the control system is configured for controlling the display system to display the threshold number of prize on symbols in fixed positions during presentation of the one or more “hold and spin” bonus games.
5. The electronic gaming machine of claim 1 , wherein:
the game is a base game;
the control system determines that (T-1) prize on symbols land during the instance of the base game, (T-1) corresponding to a number that is one less than a threshold number of prize on symbols required to trigger a feature;
the control system determines that the at least one prize on trigger symbol that lands during the instance of the base game, in addition to the (T-1) prize on symbols, will trigger the feature; and
the control system is configured for controlling the display system to present the feature after controlling the display system to present second visual effects corresponding to the award.
6. The electronic gaming machine of claim 1 , wherein the game is a base game.
7. The electronic gaming machine of claim 6 , wherein a feature is not triggered during the instance of the base game.
8. The electronic gaming machine of claim 1 , wherein the game is a free game.
9. The electronic gaming machine of claim 1 , wherein the game is a “hold and spin” bonus game.
10. The electronic gaming machine of claim 9 , wherein, prior to presenting the “hold and spin” bonus game, the control system determines that the “hold and spin” bonus game is triggered when at least a threshold number of prize on symbols land during an instance of a base game.
11. A method of controlling an electronic gaming machine, the method comprising:
determining, for a game outcome for an instance of a game and via a control system of an electronic gaming machine that is presenting the game, which symbols will be presented on a display system of the electronic gaming machine by selecting the symbols to be presented from a symbol set that includes prize on symbols and at least one prize on trigger symbol, each prize on symbol including an indication of an award corresponding to the prize on symbol, a combined value of prize on symbols being payable at a conclusion of a feature game round, wherein the game outcome does not correspond to a conclusion of a feature game round;
controlling, via the control system, the display system to present first visual effects corresponding to the game outcome, the first visual effects including moving symbols and landing of one or more prize on symbols;
determining, via the control system, an award corresponding to the game outcome, wherein for a game outcome in which the control system determines that the game outcome includes a prize on trigger symbol, the award includes a combined value of the one or more prize on symbols; and
controlling, via the control system, the display system to present second visual effects corresponding to the award.
12. The method of claim 11 , wherein the prize on symbols indicate one or more of a number of game credits, a number of currency units, an award multiplier or a progressive award.
13. The method of claim 11 , wherein the game is a base game and wherein determining which symbols will be presented on the display system involves determining that at least T prize on symbols land during the instance of the base game, T corresponding to a threshold number of prize on symbols required to trigger a feature, the method further comprising controlling the display system to present the feature after controlling the display system to present second visual effects corresponding to the award.
14. The method of claim 13 , wherein the feature comprises one or more “hold and spin” bonus games, the method further comprising controlling the display system to display the threshold number of prize on symbols in fixed positions during presentation of the one or more “hold and spin” bonus games.
15. The method of claim 11 , wherein:
the game is a base game; and
determining which symbols will be presented on the display system involves determining that (T-1) prize on symbols will land during the instance of the base game, (T-1) corresponding to a number that is one less than a threshold number of prize on symbols required to trigger a feature, the method further comprising:
determining, via the control system, that the at least one prize on trigger symbol that lands during the instance of the base game, in addition to the (T-1) prize on symbols, will trigger the feature; and
controlling the display system to present the feature after controlling the display system to present second visual effects corresponding to the award.
16. The method of claim 11 , wherein the game is a base game and wherein a feature is not triggered during the instance of the base game.
17. The method of claim 11 , wherein the game is a feature game.
18. One or more non-transitory media having software stored thereon, the software including instructions for a method of controlling an electronic gaming machine, the method comprising:
determining, for a game outcome for an instance of a game and via a control system of an electronic gaming machine that that is presenting the game, which symbols will be presented on a display system of the electronic gaming machine by selecting the symbols to be presented from a symbol set that includes prize on symbols and at least one prize on trigger symbol, each prize on symbol including an indication of an award corresponding to the prize on symbol, a combined value of prize on symbols being payable at a conclusion of a feature game round, wherein the game outcome does not correspond to a conclusion of a feature game round;
controlling, via the control system, the display system to present first visual effects corresponding to the game outcome, the first visual effects including moving symbols and landing of one or more prize on symbols;
determining, via the control system, an award corresponding to the game outcome, wherein for a game outcome in which the control system determines that the game outcome includes a prize on trigger symbol, the award includes a combined value of the one or more prize on symbols; and
controlling, via the control system, the display system to present second visual effects corresponding to the award.
19. The one or more non-transitory media of claim 18 , wherein the game is a base game and wherein determining which symbols will be presented on the display system involves determining that at least T prize on symbols land during the instance of the base game, T corresponding to a threshold number of prize on symbols required to trigger a feature, the method further comprising controlling the display system to present the feature after controlling the display system to present second visual effects corresponding to the award.
20. The one or more non-transitory media of claim 18 , wherein the game is a base game and wherein a feature is not triggered during the instance of the base game.
