in fig1 a , a smooth flat playing surface 2 is shown having marbles m 1 and m 2 , preferably of identical weight and size , mounted thereon in contact with each other . as shown in the fig1 b and 1c , the marbles m 1 and m 2 are respectively mounted in depressions d 1 and d 2 formed in the playing surface 2 . if the playing surface 2 is made of hard material such as plastic , the depressions d 1 and d 2 are preformed therein as shown in fig1 b , but if the playing surface 2 is made of soft material such as felt , the depressions d 1 and d 2 may be formed by the weight of the respective marbles m 1 and m 2 as shown in fig1 c . whereas depressions d 1 and d 2 of some sort are preferable in order to prevent the marbles m 1 and m 2 from moving in response to forces other than those resulting from the impact of a shooter marble , they are not necessary . if the depressions d 1 and d 2 are not preformed , the locations for the marbles m 1 and m 2 are designated by dots d 1 and d 2 , but both depressions d 1 and d 2 and dots d 1 and d 2 may be used . fig1 d shows a shooter marble m 3 that may or may not be the same weight and / or size as the marbles m 1 and m 2 . as described in greater detail below , an object of the game is for a player to fire the shooter marble m 3 at either m 1 or m 2 in a manner to move either m 1 or m 2 without moving both . note that for purposes of description , the present game invention is described using marbles for one embodiment . in another embodiment , disk objects , such as dimes or pennies can be used in place of the marbles . if disk objects are used , no depressions are included on the associated playing surfaces , and d 1 and d 2 would be printed positions for placement of the disks on the playing surface . lines l 1 through l 5 that are parallel to a line joining the dots d 1 and d 2 and / or the depressions d 1 and d 2 are located at different respective distances from that line . points to be earned by shooting a marble from shooting positions at any point along a line are indicated at ends of the lines . the points earned are approximately commensurate with the distance involved . by way of example , the points earned by shooting from shooting positions along the lines l 1 through l 5 may be respectively 5 , 7 , 10 , 14 , and 20 as indicated . because of the geometry involved , it is easier to make a successful shot form the ends of the lines l 1 through l 5 than from any point along them . preferably , lines l 6 and l 7 that are perpendicular to a line joining dots d 1 and d 2 and / or the depressions d 1 and d 2 and which respectively pass through d 1 and d 2 , and / or d 1 and d 2 are formed on the playing surface 2 . as shown , a player making a successful shot from a shooting position at their end that is remote from the marbles m 1 and m 2 will earn a maximum number of points such as 75 . although this is very difficult , it gives a player with a low score a chance to win and thus maintain interest in the game . because the size of the marbles m 1 and m 2 in the drawings relative to the spacing of the lines l 1 through l 7 may make it appear that it would be difficult to locate the shooting positions from which a shot is made with great accuracy , the actual dimensions of the playing surface 2 are such that this is not the case . for example , the lines l 1 through l 5 may be six inches apart , and the lines l 6 and l 7 would be one - half inch apart if the marbles m 1 and m 2 are one - half inch in diameter . the distance between l 1 and a line passing through d 1 and d 2 and / or d 1 and d 2 could be eighteen inches . the widths of the playing surface 2 could be from twelve inches to twenty - four inches . in playing a game , each player would be given a number of turns to fire a shooter marble m 3 such as shown in fig1 d , and each successful shot would earn a player the number of points designated at the end of the line from which the shot is made . the winning player is the one with the most points after a predetermined number of shots have been made . the playing surface 2 can be formed on a rigid flat board or on a layer of foldable material , felt , for example , that can be placed on a flat firm surface such as a table . whereas a playing surface could be as shown in fig1 a , shooting positions p 1 through p 7 at the ends of the lines l 1 through l 7 could be shown and the lines l 1 through l 7 eliminated as shown in fig2 a . indicia of the shooting positions p 1 through p 7 other than dots could be used . the shooting positions p 1 through p 5 need only be shown along one side of the playing surface along with the one of p 6 and p 7 that is nearer that side , but it is preferable to show all shooting positions in order to accommodate left and right - handed players . in fig2 a , the playing surface 2 is made of hard material so that depressions d 1 and d 2 for the position of the marbles m 1 and m 2 are shown . alternatively , in the second embodiment of the invention using disk objects , as previously indicated , d 1 and d 2 are printed positions , not depressions . the appearance of the playing surface shown in fig2 b is the same as that of fig2 a except that aiming lines a 1 through a 7 indicating the paths that are at the center of a range of permissible angles for successful shots from the shooting positions p 1 through p 7 are shown . in fig2 b , the playing surface 2 is made of material such as felt , for example , so that dots d 1 and d 2 are provided to show the positions of the marbles m 1 and m 2 . fig2 c is like fig2 a , but shows sectors s 1 through s 7 that represent the ranges of the angles for successful shots . note , however , that the aiming lines a 6 or a 7 remain because a successful shot must follow a 6 or a 7 precisely . in fig2 c , the surface 2 is made of hard material having both depressions d 1 and d 2 and dots d 1 and d 2 . the sectors s 1 through s 7 are defined as follows . taking the sector s 1 as an example , a line 4 is drawn from p 1 that passes the marble m 1 at a distance that is slightly greater than a radius of the shooter marble m 3 , and a line 6 is drawn p 1 that intersects the line l 7 at a distance from d 2 that is the sum of the radius of the marble m 2 and the radius of the shooter marble m 3 . although various embodiments of the invention are shown and described herein , they are not meant to be limiting . those of skill in the art may recognize certain modifications to these embodiments , which modifications are meant to be covered by the spirit and scope of the appended claims . for example , the playing surface 2 can be provided on a thin plastic or paper sheet that can be folded or rolled to pocket size for ultimate portability .
