Abstract

A method of enhancing a screen display of a gaming machine includes creating a background scene for a game screen, creating a plurality of composite symbols to overlie the background scene, and rendering at least a portion of each composite symbol transparent to enable the background scene to be viewed through the composite symbol.

Claims

1. A method of providing a screen display for a video display unit of a gaming apparatus via a gaming controller, wherein an image is displayed in a background on the screen display, the method comprising:

creating via the gaming controller a background scene having at least one animation in the background scene;

creating via the gaming controller a plurality of composite symbols, the composite symbols defining active components of a spinning reel game in which the composite symbols are spun up on a plurality of spinning reels to provide for various combinations of the composite symbols, at least one of the combinations being a winning combination, and each composite symbol having a carrier portion, and a game symbol portion;

displaying on the video display unit the background scene and the plurality of composite symbols so that the plurality of composite symbols overlie the background scene and said at least one animation occurs behind the plurality of composite symbols, and rendering the carrier portion of each of the composite symbols transparent so that at least a portion of the background scene can be viewed through the carrier portions of the symbols;

determining via the gaming controller a winning combination from the displayed selected symbols; and

wherein displaying the plurality of composite symbols comprises arranging via the gaming controller groups of the composite symbols end-to-end and representing each group as moving so as to represent movement of the plurality of spinning reels and then stopping to display at least one said combination of composite symbols, and

wherein at least a portion of the background scene can be viewed through the carrier portion of the displayed composite symbols, both when the composite symbols are represented as moving and when the composite symbols are represented as stopped, and

wherein in response to determining via the gaming controller that the stopped at least one said combination of composite symbols forms a winning combination, animating the composite symbols which forms the winning combination such that the respective composite symbols which forms the winning combination are temporarily rendered transparent such that the background scene underlying the respective composite symbols is visible therethrough before returning the respective composite symbols to an opaque state, and

wherein in response to the respective composite symbols being temporarily rendered transparent, revealing said background scene and said at least one animation behind the temporarily transparent symbols, and awarding via the gaming controller one or more bonus prizes in respect of such revealed background scene and said at least one animation.

2. The method of claim 1, wherein said rendering the carrier portions transparent comprises setting said carrier portions to an appropriate alpha channel value in an alpha channel range.

3. The method of claim 2, wherein said setting said carrier portion includes setting said carrier portion to an alpha channel setting which results in completely transparent carrier portions.

4. A method of providing a screen display for a video display unit of a gaming apparatus via a gaming controller, the method comprising:

creating via the gaming controller (1) a background scene defining a passive component of a game and (2) at least one animation in the background scene;

creating via the gaming controller a plurality of symbols, the symbols defining active components of the game, wherein play of the game involves selecting a plurality of the symbols to provide for various combinations of symbols, at least one of the combinations being a winning combination that results in the awarding of an award, wherein each symbol has a carrier portion, and a game symbol portion; and

displaying on the video display unit the background scene and displaying the selected plurality of symbols in a pattern overlying the background scene and said at least one animation occurring behind the selected plurality of symbols, the carrier portion of each of the symbols being substantially transparent so that at least a portion of the background scene can be viewed through the carrier portions of the symbols while the symbol portion is initially rendered opaque;

determining via the gaming controller a winning combination from the displayed selected symbols; and

wherein

in response to determining via the gaming controller a winning combination, animating the selected symbols of the winning combination such that the respective selected symbols of the winning combination are temporarily rendered transparent such that the background scene underlying the respective selected symbols is visible therethrough before returning the respective selected symbols to an opaque state, and

wherein in response to the respective selected symbols being temporarily rendered transparent, revealing said background scene and said at least one animation behind the temporarily transparent symbols, and awarding one or more bonus prizes in respect of such revealed background scene and said at least one animation.

5. The method of claim 4, wherein said displaying the selected plurality of symbols in a pattern includes arranging the symbols end-to-end so that the carrier portion of at least certain symbols define in combination a transparent reel strip.

6. The method of claim 5, comprising rendering said carrier portions of said at least certain symbols entirely transparent and providing the screen display so that the only visible portion of the reel strips are the game symbol portions of the said at least certain symbols.
