CROSS REFERENCE TO RELATED APPLICATIONS 
     The present invention claims the benefit and priority to U.S. provisional patent application No. 62/153,593, filed on Apr. 28, 2015 and entitled, Ball Race Wagering Game Apparatus and Methods of Use. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a ball race wagering game apparatus and methods of use. 
     2. Background 
     Many people enjoy wagering on various types of races, including horse and dog races. This type of wagering activity provides a unique experience as those wagering can root for the winner. The anticipation builds until the winner crosses the finish line. In addition, racing events provide a wide range of wagering options, including win, place, show, trifecta, exacta, quinella, and the like. Unfortunately, horse and dog races take a considerable amount of time and money to set up and operate. Race tracks for horse and dog races often do not have other casino type gaming which makes the activities limited at these venues. Furthermore, there is typically a long period of time between races. Those interested in wagering on successive races have to wait a rather long time between races. There exists a need for a racing game that is quick and easy to operate and can be located within casino or race track venue. 
     SUMMARY OF THE INVENTION 
     The invention is directed to a ball race wagering game apparatus and methods of use. A ball race wagering game apparatus comprises a plurality of runs comprising a decline plane and deflectors whereby a plurality of balls roll from a starting elevated end to a lower finish end. In an exemplary embodiment, a ball race wagering game apparatus comprises first and second runs that are aligned and offset vertically from each other. The first decline plane has an elevated starting end and a lower end that is above the starting end of a second decline plane. In this embodiment, a plurality of balls drop from the lower end of the first decline plane to the starting end of the second decline plane. Each run may comprise a plurality of deflectors, whereby balls rolling down the decline planes will randomly impact with the deflectors to change their direction. In one embodiment, a shortcut conduit is configured between the first and second decline planes. In another embodiment, the ball race game apparatus comprises a rotating deflector that may propel balls back up the decline plane. In still, another embodiment, one or more stops are configured on a decline plane to trap and hold a ball and prevent it from finishing the race, or reaching the finish line. 
     The ball race wagering game apparatus provides opportunities to wager on the outcome of a race. Any suitable type of wager is contemplated including those typical of horse race betting such as, win, place show, trifecta, superfecta, quinella, exacta and the like. The ball race wagering game apparatus provides some additional types of wagering including wagering on a ball not to finish, wagering on a select number or subset of balls to finish first. For example, in one embodiment, the balls may have ball designations like those of 16 billiard balls with fifteen numbered balls and a que ball. There may be seven with a stripe and seven being solid in color. A person may wager on any of the solids to finish first for example. In addition, a person may wager on a color designation to finish which may include two balls, one from the striped group and one from the solid group. Any suitable manner to place the bets are contemplated including a betting table or mat having specific wagering designations for the placement of chips, much like a roulette table. In one embodiment a betting surface, or table is provided with a plurality of different betting locations, each having a betting designation such as ball number, color, stripes; much like that of a roulette-betting table. A person may place a wager on one or more of the betting locations and receive a winning equal to the odds for that wager. Another wagering method includes placing a wager by writing down or otherwise communicating a wager. A betting slip may be handed in or a person may simply verbally communicate their wager to an attendant at a wagering window, for example. Still another way to place a wager is a combination of the betting table and communication to an attendant that facilitates wagering at the betting table. A person may write down their wager on a slip and hand it to a betting table attendant, who then places their wager on the table. In still another embodiment, a person may place a wager through an interface with an electronic device, such as a computer configured as a wagering station, or kiosk. A portable electronic device may be configured to place wagers as well, such as a mobile phone or tablet computer. Any suitable method of placing a wager and combinations thereof may be employed in the present invention. 
     A run and decline plane may have any suitable dimensions or aspect ratio of length to width. A decline plane may have a length that is about 0.5 m or longer, about 1 m or longer, about 2 m or longer and any range of lengths between and including the lengths listed. A decline plane may have any suitable width and in an exemplary embodiment, the width is no more than one-half the length. The aspect ratio of length to width of the decline plane may be 1.5 or more, 2 or more, 3 or more, 5 or more 10 or more and any range between and including the aspect ratios provided. 
     A run may have any number of deflectors including five or more, eight or more, ten or more, twenty or more, and any range between and including the number of deflectors provided. A first run and second run may have the same or similar number of deflectors or one run may have more deflectors than the other run, such as 1.5 times more, 2 times more, 3 times more and the like. A deflector may be a discrete deflector that is not coupled with or extends from a wall of the game apparatus. A discrete deflector may have a perimeter that is free standing and not coupled to any side or end wall. A deflector may be a wall deflector, or a deflector that is coupled with and extends from a wall of the game apparatus, such as a side-wall or end wall, for example. A game apparatus may comprise one or more roll-deflectors, or a deflector that has an elongated linear surface that is at least three times longer than the diameter of a ball used in the ball race game, wherein said ball may roll along the roll deflector. An elongated linear surface of a roll-deflector may extend across the width of a decline plane and be configured at some offset angle to the length axis of the decline plane. A decline plane may comprise a channel deflector, or a pair of roll-deflectors that are oriented to guide a ball down to a channel opening or space between the two roll-deflectors. A channel deflector may comprise a pair of roll deflectors that extend from opposing side-walls of the game apparatus toward the center-line of the decline plane where there is a space through which one or more balls are allowed to roll. 
     A deflector may have any cross-sectional shape across the vertical extended axis, such as circular, triangular, square, rectangular, elongated, irregular and the like. A deflector may extend up from a decline plane surface or from a top, bottom or side-wall. A deflector may have a height, or length extension from the decline plane surface that is greater than the diameter of the balls used in the ball race game apparatus. A deflector may have flat or planar surfaces, as is the case with deflectors that are blocks, or may comprise curved or rounded surfaces as is the case with a cylindrical type deflector. In an exemplary embodiment, a run comprises a plurality of square block deflectors having planar surfaces that extend up from the decline plane surface to provide an impact surface for the balls. In another embodiment, a run comprises deflectors having curved surfaces, such as a cylindrical shaped deflector that extends up from the decline plane. A run may, comprise block shaped deflectors, having planar surfaces for contact with the balls, for example. In another embodiment, a deflector may have a height that is less than the diameter of the ball and a ball, may, in some cases, hit and travel over the deflector. 
     A ball race game apparatus may comprise one or more stops that are configured to stop and retain a ball from rolling down the decline plane. A stop may be a discrete stop that is configured within the decline plane and not coupled with a side or end wall of the run. A discrete stop may comprise two deflector extensions that form a pocket or V-shape to capture a ball as it rolls down the decline plane. A stop may also be configured as a wall stop, or along a side or end wall, and comprise a deflector that extends from the wall in a manner to capture a ball. For example, a wall stop may extend from a wall up toward the elevated end to form a pocket to trap and retain one or more balls. 
     A run may comprise a spinning deflector configured to impart energy into a ball that contacts it. A spinning deflector may be any suitable shape, including block shaped and may comprise an activation button that enables a user or wagering person to press the activation button as desired. In one embodiment, a spinning deflector may impact a ball, and propel it up the decline plane, thereby increasing the time for that ball to finish. 
     Between runs there may be a transfer conduit configured to move the balls from the lower end of the first decline plane to the elevated starting end of a subsequent decline plane. A transfer conduit may be a tube having a transfer inlet on the first decline plane and a transfer outlet configured to deliver balls to a second decline plane. The lower end of the first decline plane may be elevated in height from the starting end of the second decline plane. A transfer conduit may be configured to drop the balls from the first decline plane to the second decline plane. 
     A ball race wagering game apparatus may comprise a shortcut conduit that is configured to allow one or more balls to pass from a first decline plane to a second decline plane and bypass one or more deflectors. A shortcut conduit may have an inlet that is configured some distance from the lower end of a first decline plane and an outlet that is configured some distance down from the starting end of a second decline plane. A shortcut tunnel may be sized to only allow one ball at a time to pass through the conduit or may be larger to allow two or more balls to pass, through at one time. 
     An exemplary ball race wagering, game apparatus comprises a starting block configured to hold a plurality of balls for the start of a race. A starting block may comprise a stop or recesses to hold the plurality of balls and prevent them from rolling down the first run. A trigger or lever may be coupled with a starting block to allow the release of the balls to start the race. A starting block may be configured at some height above the starting end of the first run or decline plane. At the beginning of a race, the plurality of balls may be released from this elevated height and drop down onto the first decline plane. A ball race wagering game apparatus may also comprise a starting chamber, or a confined area wherein the plurality of balls can bounce before exiting the starting chamber to roll down the first decline plane. A starting chamber may comprise a transparent starting shield configured to allow participants in the ball race wagering game to view the balls within the starting chamber. 
     An exemplary ball race wagering game apparatus comprises a finish collector configured to collect the plurality of balls in the order in which they finish the ball race. In an exemplary embodiment, the finish collector collects the balls in line, with the first ball to finish at the bottom of the collector, and second ball to finish next to the first and so on. A finish collector may have finish indicators to show the finish order of the balls. 
     Any suitable type of balls may be used in the ball race wagering game apparatus and any suitable type of ball indicator may be configured on the ball. In an exemplary embodiment, the balls have ball indicators resembling those of common billiard balls, with numbers one through fifteen and having different colors. Standard billiard balls include balls numbered 1 to 7 that have different colors and balls numbered 9 to 15 that have a corresponding striped color, and a ball numbered 8 that is black. In addition, a white cue ball is used in billiards making the total number of balls sixteen. Any number of balls may be used in the ball race wagering game apparatus however, including at least three, at least five, at least ten, at least fifteen, at least 20 and any range between and including the number of balls listed. A ball used for the ball race wagering game apparatus may be a hard ball, such as those used in billiards, or a ball that is elastic and bounces, such as a Super-ball available from Gumballs Inc., and having a 32 mm diameter. Super-balls come in a range of diameters, from 27 mm to 49 mm for example. 
     A ball race wagering game apparatus may have any number of runs and in an exemplary embodiment, a first and a second run are configured in line with each other. A first run may be configured at some offset angle or any other orientation with respect to the first run. 
     The summary of the invention is provided as a general introduction to some of the embodiments of the invention, and is not intended to be limiting. Additional example embodiments including variations and alternative configurations of the invention are provided herein.
