General
At the commencement of each match, you will be issued with a timer, a ball marker and (for singles matches only) a spare cue ball. Return these to the adjudicator at the end of the match.
There is a jigger and a spider under each table. Check that these are in place before and after each frame so that time-outs to access a rest are not be required.
For tight snookers where an extra cue ball or string is required, an adjudicator must be called.
If an adjudicator is required, do not leave the table. If you cannot catch the attention of an adjudicator, ask someone to get one for you.
