Boost stage with metamorphic graphical element
View Patent ↗In an electronic gaming device, a boost stage uses a metamorphic graphical element. The boost stage starts when predetermined condition such as a “near-miss” condition occurs and provides an additional opportunity to satisfy a trigger condition for a supplemental feature. The metamorphic graphical element indicates how many times the predetermined condition has occurred since the supplemental feature was last triggered. When the boost stage starts, the state of the metamorphic graphical element can advance to a higher state value, visually indicating the additional opportunity to satisfy the trigger condition for the supplemental feature. For the boost stage, if the previous result (associated with the predetermined condition) is enhanced enough to satisfy the trigger condition, the supplemental feature is triggered and the metamorphic graphical element is reset. Otherwise, the boost stage finishes but the advanced state value of the metamorphic graphical element is maintained.

A computer system comprising one or more processors and memory readable by the one or more processors, the memory having stored thereon computer-executable instructions for causing the one or more processors, when programmed thereby, to perform operations to control a user interface of an electronic gaming device, the operations comprising:
determining that a result of a game instance of one or more game instances is within a threshold range of satisfying a trigger condition for a supplemental feature;
providing, via the user interface, a metamorphic graphical element indicating how many times the one or more game instances have been within the threshold range of satisfying the trigger condition for the supplemental feature during a tracking period, wherein the metamorphic graphical element has a current state value; and
in response to the determination that the result of a game instance is within the threshold range:
based at least in part on a result of a lookup operation for a random number in a lookup table, determining whether the trigger condition for the supplemental feature is satisfied; and
in accordance with a determination that the trigger condition is satisfied based at least in part on the result of the lookup operation:
triggering the supplemental feature.
2. The computer system of claim 1 , wherein the supplemental feature is a bonus reel game, a special mode that adds wild symbols to one or more sets of reels of a base reel game, a special mode that adds scatter symbols to the one or more sets of reels of the base reel game, or another special mode.
3. The computer system of claim 1 , wherein the trigger condition for the supplemental feature is a threshold count of target symbols in one or more sets of reels of the game instance.
4. The computer system of claim 3 , wherein the threshold range is a count of target symbols in one or more sets of reels of the game instance.
5. The computer system of claim 4 , wherein the threshold range is a difference relative to the threshold count of target symbols.
6. The computer system of claim 5 , wherein the threshold range is one target symbol less than the threshold count of target symbols.
7. The computer system of claim 1 , wherein the tracking period:
restarts whenever the supplemental feature is triggered, such that the metamorphic graphical element indicates how many times the game instance and the one or more game instances have been within the threshold range since the supplemental feature was last triggered.
8. The computer system of claim 1 , wherein the current state value is one of multiple state values wherein the multiple state values include:
an initial state value that corresponds to an initial depiction of the metamorphic graphical element; and
multiple progressively-changing state values that correspond to successive depictions of the metamorphic graphical element.
9. The computer system of claim 8 , wherein the metamorphic graphical element is a container, and wherein:
the initial depiction shows the container with a minimal amount of content, and the successive depictions show the container with successively larger amounts of content; or
the initial depiction shows the container with a maximal amount of content, and the successive depictions show the container with successively smaller amounts of content.
10. The computer system of claim 8 , wherein the successive depictions show the metamorphic graphical element at different stages of completion along a progression from the initial depiction to a final depiction, the final depiction being associated with a final state value among the multiple progressively-changing state values.
11. The computer system of claim 1 , wherein the electronic gaming device is an electronic gaming machine with physical reels and video reels, and wherein the result of the game instance is a count of target symbols stopped in the video reels, the target symbols being selectively added to the video reels depending on results for the physical reels.
12. The computer system of claim 1 , wherein the current state is advanced to the next state value, if any, among multiple state values by:
determining whether the current state is a highest state value;
if the current state is the highest state value, making no change to the current state; and
otherwise, the current state not being the highest state value, adjusting the current state to have the next state value.
13. The computer system of claim 1 , wherein the current state of the metamorphic graphical element is adjusted from any of multiple electronic gaming devices, and wherein the supplemental feature, when triggered, is:
shared among the any of the multiple electronic devices; or
allocated to only one of the multiple electronic gaming devices.
14. The computer system of claim 1 , the operations further comprising:
in response to the supplemental feature being triggered, the metamorphic graphical element is obscured by an animation of the supplemental feature.
15. The computer system of claim 1 , the operations further comprising:
in response to the supplemental feature being triggered, displaying an animation transitioning to the supplemental feature.
16. The computer system of claim 1 , the operations further comprising:
in response to the supplemental feature being triggered, displaying a new target symbol to the game instance.
17. The computer system of claim 1 , the operations further comprising:
in response to completion of the supplemental feature, the current state value of the metamorphic graphical element is reset.
18. The computer system of claim 17 , wherein the current state value is reset to an initial state value.
19. In a computer system, a method of controlling a user interface of an electronic gaming device, the method comprising:
determining that a result of a game instance of one or more game instances is within a threshold range of satisfying a trigger condition for a supplemental feature;
providing, via the user interface, a metamorphic graphical element indicating how many times the one or more game instances have been within the threshold range of satisfying the trigger condition for the supplemental feature during a tracking period, wherein the metamorphic graphical element has a current state value; and
in response to the determination that the result of a game instance is within the threshold range:
based at least in part on a result of a lookup operation for a random number in a lookup table, determining whether the trigger condition for the supplemental feature is satisfied; and
in accordance with a determination that the trigger condition is satisfied based at least in part on the result of the lookup operation:
triggering the supplemental feature.
20. A computer system comprising one or more processors and memory readable by the one or more processors, the memory having stored thereon computer-executable instructions for causing the one or more processors, when programmed thereby, to perform operations to control a user interface of an electronic gaming device, the operations comprising:
displaying a metamorphic graphical element indicating how many times one or more game instances have been within a threshold range of satisfying a trigger condition for a supplemental feature during a tracking period, wherein the metamorphic graphical element has a current state value;
displaying a result of at least one game instance of the one or more game instances that is within the threshold range of satisfying the trigger condition for the supplemental feature during the tracking period; and
in response to the determination that the result of a game instance is within the threshold range:
