The 2010 world champion has pulled the plug on his console addiction to focus on landing a second Crucible title.
The 35-year-old, now based in England, fired breaks of 70 and 76 to make sure of his place in the last 16.
"It was taking over and affecting my life and it is a serious issue".
"Once I turn the computer on I can easily play them for 12 hours straight". In China there are gaming addiction camps where they take kids that are hooked.
"This time past year I was talking here after a first-round defeat, so I am very pleased to be through to the next round".
"I've got quite an addictive personality and I've decided to just make a clean break from them".
"The years I had the 100 centuries, I should probably had around 120 because I got addicted like hell to Federation Internationale de Football Association 14", Robertson said.
And Robertson urged Trump to look at the example set by the late former Masters champion Paul Hunter, who even when suffering from cancer before his death in 2006 did not neglect his off-table responsibilities.
But if Robertson had not been so engaged with the gaming culture as a teenager, he believes his career would have taken off sooner.
"I was heavily addicted to a game called Diablo II".
"I've had really good application in my practice after dragging myself away from playing too many video games", he said. It got to the point back home in Australia that my mum would have to create an account and log on to see if I was on it instead of playing snooker.
"So all of a sudden I would see "Alison has come online". And I'd be like, "Oh my god, quick, get out", then she'd start typing and I'd be busted.
However, Robertson says he has managed to wean himself off them but like any addict counts getting through each day without playing them as a success.
"If you are a single guy and work in a normal job you can get around it. But you can't win professional snooker matches when you are exhausted".
