Cue extensions are allowed in APA.
In general, any piece of equipment designed specifically for pocket billiards, with the exception of laser devices and mechanical cues, is acceptable in APA League play. Some specialty cues (see SPECIALTY CUES described in definitions) may be limited in use. Special equipment, such as bridges and cue extenders, are legal.
Other than the 8 ball in 8 ball or the cue ball, all balls are spotted immediately when they are jumped off the table.
