In the same day I saw two different instances of how this should be handled. When the 15th (break ball for the next rack) ends up in the rack area where should it be placed? Once I noticed that they just made a full rack and once it was spotted to the head of the table. I've uncovered two sources on which is correct and they are in conflict. What say you experts? Thanks.
The official rules are the World Standardized Rules which you can find on the WPA website. Another good source is the CSI/BCAPL rules which are on their website. The CSI rules have more explanation but are not identical to the WSR. Everyone who is really interested in any game should read through the rules of that game at least once. Few do.
To save a little searching:
If the 15th object ball is in the rack....
... usually it spots on the head spot, but
... if the cue ball is also in the rack, all 15 balls rack, or
... if the cue ball obstructs the head spot, the object ball goes on the center spot.
