Gaming machine with a dynamic bonus modifier

1. A gaming apparatus implementing a bonus gaming feature in response to an outcome of a base game playable on the gaming apparatus, said bonus gaming feature and said base game being implemented by a controller and a display controlled by the controller, said bonus gaming feature being configured by the controller to award a bonus outcome from at least one awardable bonus outcome, wherein at least one of said awardable bonus outcomes is determined on the basis of a dynamic bonus modifier, said bonus gaming feature including at least one motion indicator displayed on the display and indicative of movement of an indicator about a displayed circle, wherein said displayed circle is divided into a plurality of sectors each having a corresponding displayed sector value, wherein said displayed circle includes a central region interior to said sectors for displaying a value of a sector value modifier, wherein during play of said bonus gaming feature a counter is incremented by the controller in relation to a degree of the movement of said motion indicator for every revolution of said motion indicator about said displayed circle to display a change of the value of the sector value modifier, and wherein said dynamic bonus modifier is determined by the controller and corresponds to a combination of the displayed sector value of the sector at which the motion indicator stops and the value of the sector value modifier.

2. A gaming apparatus as claimed in claim 1 wherein said counter is further adjusted in concert with at least one of the following parameters of the movement of the motion indicator:

a speed of the motion of the motion indicator; and

a duration of the motion of the motion indicator.

3. A gaming apparatus as claimed in claim 1 , wherein the counter has a value that increases from a start value and does not decrease prior to awarding the bonus outcome.

4. A gaming apparatus as claimed in claim 1 , wherein the value of the counter is independent of the relative positions of the counter and the motion indicator when the motion indicator stops, except to the extent that the stopping position is related to the to the degree of rotation of the motion indicator.

5. A gaming apparatus including a controller and a display controlled by the controller to implement a bonus gaming feature as part of a game playable on the gaming apparatus, said controller being configured to provide the bonus gaming feature to award a bonus outcome from at least one awardable bonus outcome, wherein at least one of said awardable bonus outcomes is determined by said controller using a dynamic bonus modifier, said bonus gaming feature including at least one motion indicator provided on the display indicative of motion of the indicator about a displayed circle that is divided into a plurality of sectors each having a corresponding displayed sector value, and wherein said gaming apparatus includes a region controlled by the controller for displaying a value of a sector value modifier, wherein the sector value modifier corresponds to and is incremented based on a degree of the motion of said motion indicator for every revolution of said motion indicator about said displayed circle, and wherein during play of the bonus gaming feature, the controller adjusts the value of said dynamic bonus modifier in relation to the displayed sector value of the sector at which the motion of the motion indicator terminates and the sector value modifier.

6. A gaming apparatus as claimed in claim 5 wherein said controller determines the bonus outcome by multiplying the sector value of the sector at which the motion indicator stops with the value of the sector value modifier.

7. A gaming apparatus as claimed in claim 5 further comprising a base bonus component implemented by the controller.

8. A gaming apparatus as claimed in claim 5 , further comprising a base bonus component, wherein said base bonus component is an award of a number of bonus games, and wherein an additional bonus is determined by applying said dynamic bonus modifier to a sum of all bonus outcomes awarded using at least one of the following methods:

multiplying said sum of all bonus outcomes awarded by said dynamic bonus modifier; and

adding said sum of all bonus outcomes awarded to said dynamic bonus modifier.

9. A gaming apparatus as claimed in claim 5 wherein said sector value modifier is selected from a group including:

a bonus multiplier;

a progressive jackpot bonus multiplier; and

a progressive jackpot.

10. A gaming apparatus having a display and a game controller arranged to control images of symbols displayed on the display, said game controller being arranged to control a game wherein at least one random event is caused to be displayed on said display and, if a predefined winning event occurs in a base game, a bonus game feature is awarded, said bonus game feature being configured to award a bonus outcome from at least one awardable bonus outcome, wherein at least one of said awardable bonus outcomes is determined on the basis of a dynamic bonus modifier, said game controller further configured to control the display during the bonus game feature to:

display a circle that is divided into a plurality of sectors each having a corresponding displayed prize,

display a value of a prize value modifier,

display and control motion of at least one motion indicator indicative of motion of an indicator about the circle,

wherein said prize value modifier increases based on a degree of the motion of said motion indicator for every revolution of said motion indicator about said circle,

wherein the value of at least one of said awardable bonus outcomes is determined by said dynamic bonus modifier by mathematically combining the prize value modifier and a prize value, and wherein the motion indicator identifies which of the sectors and corresponding displayed prize is used to determine the prize value.
