Your score is determined by a mathematical formula: the number of the billiard ball multiplied by the current ball-potting rate multiplied by 10. Each time you pot a billiard ball, your rate will increase by one point. If you pot the cue ball at the same time, you will not score any points and will have to retake your shot.

If you pot two or more balls with one shot, your rate will increase faster. If you fail to pot a billiard ball, or if you pot the cue ball into a pocket, your rate will reset to one.

If your rate increases to 20, 25, 30, 35 or more, you will gain a spare ball each time as a bonus.
