Bank shot guide for billiards

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.
