Luke Littler has apologised for denying a fan a huge payout by failing to hit a nine-darter against Ryan Meikle.
Any perfect legs at Alexandra Palace will result in one lucky fan winning £60,000.
Asked if he feels any extra pressure because of the rule, Littler told Sky Sports: “It’s definitely becoming a frustration in a good way.
“Obviously, as soon as you make the switch to the treble 19, your eyes light up.
“I heard the camera pan around to the winner, so I’m sorry whoever you are! I’ll try again.”
