Here the 8 ball is at position 50. In order to hit the 8 ball using the diamond system we need to select the rail positions which will add up to 50. We first select the 30 diamond on the right rail. The rebound off the rail will take the cue ball to the 7 diamond on the far end rail and in turn to the 20 diamond. The 7 does not enter into the equation, however, the 30 and the 20 equal 50 and the cue ball will hit the 8 ball at position 50. The red line indicates the imaginary travel of the cue ball.
In this picture, you can see two of the diamonds lit on the specially modified pool table. One at diamond 30 and the other at diamond 7. Again, the red line indicates the imaginary travel of the cue ball.
In this picture, we see the diamond system using only two rails. The principle is the same in that the 8 ball is at position 50. The cue ball is at position 40 and we must make our shot add up to 50. The diamonds at 6 and 10 are lit up to indicate where we should aim the cue ball in order to hit the 8 ball. The cue ball is at 40 and so we must hit the 10 diamond if we are to make the shot.
