The markings can be aligned along the length of the pool cue shaft, tape measure, floor, or floor accessory at predetermined distances to provide graphical symbols that can aid a player in calculating bank angle game parameters applicable to the game table being played on. The markings are designed to represent extensions of readily observable existing diamond markings typically located on the pool table side rails. Groups of the markings may be color coded and/or rotationally separated from each other to visibly display the appropriate group of markings applicable to a particular length of pool table being used. ## Claims ### Claim 1 A pool cue stick for improving bank shots on a game table having two parallel side rails bounded by two parallel end rails, and rail markings disposed at specified intervals on the rails, the pool cue stick comprising: a shaft having a length, a longitudinal axis, a substantially smooth, continuous exterior surface, a tip end, a distal end, and a ferrule-receiving portion of the pool cue stick proximate the tip end; and a bank shot guide comprising at least four easily observable visible markings disposed longitudinally along the exterior surface, each of the visible markings being located at least one predetermined distance along the exterior surface from another one of the visible markings on the exterior surface, the at least one predetermined distances being equal to each other and equal to the specified intervals of the game table rail markings, wherein a player can position the pool cue to extend beyond the rail being sighted thereby forming an extension of the specified intervals of the game table rail markings by laying cue stick in line with an end of one of the side or end rails whereby the player can sight a cue ball to determine the optimum position on the side or end rails opposite the player's pool cue stick position to aim for a bank shot that strikes an object ball. ### Claim 2 (depends on 1) The pool cue stick according to claim 1, wherein the visible markings are graphical symbols for aiding a player in calculating bank angle game parameters applicable to the game table being played on. ### Claim 3 (depends on 1) The pool cue stick according to claim 1, wherein the visible markings are diamond markings corresponding to rail markings on the game table being used. ### Claim 4 (depends on 1) The pool cue stick according to claim 1, wherein the predetermined distance between the visible markings and the specified intervals of the game table rail markings are proportional to the size of the game table being used. ### Claim 5 (depends on 1) The pool cue stick according to claim 1, wherein the at least four easily observable visible markings disposed longitudinally along the exterior surface comprise a group of visible markings, wherein at least three groups of visible markings are rotationally separately disposed on the exterior surface of the pool cue stick, the separate visible marking groups being respectively associated with a uniquely sized game table. ### Claim 6 (depends on 5) The pool cue stick according to claim 5, wherein groups of the markings are color coded. ### Claim 7 (depends on 6) The pool cue stick according to claim 6, wherein a first group of the color coded markings corresponds to markings found on a 7-foot game table, a second group of the color coded markings corresponds to markings found on an 8-foot game table, and a third group of the color coded markings corresponds to markings found on a 9-foot game table. ### Claim 8 A bank shot guide system including a pool cue stick and a table for playing a pool game thereon, the table having two parallel side rails bounded by two parallel end rails, and rail markings disposed at specified intervals on the rails, the pool cue stick comprising: a shaft having a length, a longitudinal axis, a substantially smooth, continuous exterior surface, a tip end, a distal end, and a ferrule-receiving portion of the pool cue stick proximate the tip end; and a bank shot guide comprising at least four easily observable visible markings disposed longitudinally along the exterior surface, each of the visible markings being located at least a predetermined distance along the exterior surface from another one of the visible markings on the exterior surface, the at least one predetermined distances being equal to each other and equal to the specified intervals of the game table rail markings, wherein a player can position the pool cue to extend beyond the rail being sighted thereby forming an extension of the specified intervals of the game table rail markings by laying cue stick in line with an end of one of the side or end rails whereby the player can sight a cue ball to determine the optimum position on the side or end rails opposite the player's pool cue stick position to aim for a bank shot that strikes an object ball. ### Claim 9 (depends on 8) The bank shot guide system according to claim 8, wherein the at least four easily observable visible markings disposed longitudinally along the exterior surface comprise a group of visible markings, wherein at least three groups of visible markings are rotationally separately disposed on the exterior surface of the pool cue stick, the separate visible marking groups being respectively associated with a uniquely sized game table. ### Claim 10 (depends on 9) The bank shot guide system according to claim 9, wherein groups of the markings are color coded. ### Claim 11 (depends on 10) The bank shot guide system according to claim 10, wherein a first group of the color coded markings corresponds to markings found on a 7-foot game table, a second group of the color coded markings corresponds to markings found on an 8-foot game table, and a third group of the color coded markings corresponds to markings found on a 9-foot game table. ### Claim 12 (depends on 8) The bank shot guide system according to claim 8, wherein the visible markings are graphical symbols for aiding a player in calculating bank angle game parameters applicable to the game table being played on. ### Claim 13 (depends on 8) The bank shot guide system according to claim 8, wherein the visible markings are diamond markings corresponding to rail markings on the game table being used. ### Claim 14 (depends on 8) The bank shot guide system according to claim 8, wherein the predetermined distance between the visible markings and the specified intervals of the game table rail markings are proportional to the size of the game table being used. ### Claim 15 (depends on 8) The bank shot guide system according to claim 8, wherein the table has pockets located at the corners and at the midpoint of each side rail.
