But he has also suffered some agonising defeats at the Crucible.
His 13-12 loss to John Higgins in the last 16 on Monday afternoon barely seemed believable when he cruised 9-4 clear on Sunday evening, but missing several key balls came back to haunt him as his old rival completed a remarkable comeback.
Where does his defeat to Higgins rank in his all-time list of shock World Championship exits?
10. Lost 10-9 to David Gray, first round (2000)
O'Sullivan had yet to win the sport's biggest title when he faced former English amateur champion David Gray in the first round.
Qualifier Gray, 21, was a 200-1 outsider, but he upset the form book despite watching O'Sullivan produce five centuries. O'Sullivan led 5-1, but saw the world No. 60 complete a rousing comeback to advance.
"It's David's day, and good luck to him," said O'Sullivan. "He played a great match. He was superb, and deserved to win.
"I never really took the match by the scruff of the neck, even though I made five centuries. It's hard to take, but that's the way it goes. That's snooker."
Indeed, it is. Gray would lose 13-1 to Dominic Dale in the second round, amassing only 208 points, a record low for a best-of-25 match in Sheffield.

9. Lost 13-3 to John Parrott, second round (1994)
Teenager O'Sullivan was the UK champion, following his totemic 10-6 win over Stephen Hendry five months earlier, when he washed up in Sheffield for the second time in 1994.
A match with the 1991 world champion John Parrott looked tricky, but nobody envisaged the young Rocket Ronnie suffering an 8-0 session whitewash from trailing 5-3 as the Crucible provided a punishing experience.
It was the first of six straight wins Parrott enjoyed over O'Sullivan, ending his career with an 8-4 winning record against the snooker GOAT.
"John Parrott was that player for me. I think he beat me the first seven times we played," said O'Sullivan in citing problematic opponents.
"He played great, and I never used to play against him. That’s sometimes what happens, you know."
8. Lost 18-14 to Mark Selby, final (2014)
Mark Selby decimated The Rocket's dreams of a sixth world title when he recovered from trailing 10-5 to win the first of his four Crucible crowns world final in 2014, a defeat built on starving O’Sullivan of chances and momentum.
In an attritional battle bogged down by tactics, O'Sullivan missed a simple pink to a middle pocket to lead 12-11, a crucial juncture in falling behind and slowly out of contention for a third straight world crown.
"The match I’d like to play again would be Selby in the 2014 final, because I’d have played it differently," he said. "I would have done everything I could to not get bogged down, and keep the game open.

"When I looked back, I thought I’d got sucked into his game. It wasn’t until after that game that I thought, ‘yeah, I might lose to you, and I probably will lose to you again, but it’s going to be on my terms’."
As it was, O'Sullivan gained a measure of revenge by running in breaks of 138, 71 and 64 from 16-14 down in the 2020 semi-finals on his way to claiming the sixth of his seven titles.
7. Lost 13-12 to Barry Hawkins, second round (2016)
O’Sullivan put a brave face on somehow losing 13-12 to Barry Hawkins in the last 16 a decade ago.
The tournament favourite was edged out by his fellow Englishman in the final match of the second round, after recovering from trailing 12-9 to force a deciding frame with stirring breaks of 124, 88 and 63, only to come up agonisingly short.
It was a match O'Sullivan felt he could and probably should have won, having lost several close frames that could easily have gone the other way amid some of his usual heavy break-building, which also included runs of 139, 88, 103, 68, 118, 82, 89, 93 and 70.

Hawkins slotted a red into a baulk pocket before compiling 56 to set him up for a rare win over an opponent who overcame him 18-12 in the 2013 world final, and drubbed him 10-1 in the Masters final in January.
"It was a shot to nothing," said O’Sullivan. "He wasn’t leaving anything on if he missed, but it was a good pot, and he made a good 50-odd break. All credit to Barry, and I wish him well for the rest of the tournament."
6. Lost 17-7 to Zhao Xintong, semi-final (2025)
After changing the tip and ferrule on his cue overnight before resuming his semi-final against Zhao Xintong, level at 4-4, O'Sullivan lost all eight frames in a farcical morning session on Friday.
Having led 4-3 on Thursday afternoon after producing four 60+ knocks, it meant the seven-time champion lost nine straight frames before being eliminated from the Sheffield event with a session to spare, as former UK champion Zhao eased through to the showpiece final with a clubbing victory.
Zhao applauded his revered opponent, who had inspired and helped him to pursue a career in the sport. It was a poignant moment, but one which signalled a changing of the cue rather than the guard.

"I have lost what I used to have. I’m so confused. It feels really a struggle," said O'Sullivan after suffering one of his worst beatings in his 33rd straight appearance at the Crucible.
"I don’t know if it was me, the cue tip or the ferrule. I didn’t know where the white ball was going."
It was only the fourth time he had lost all eight frames in a session in Sheffield since his tournament debut in 1993.
5. Lost 13-12 to John Higgins, second round (2026)
Despite defeating Higgins 18-14 to claim his first world title in the 2001 final, O'Sullivan has encountered plenty of problems in trying to quell the threat of the doughty Scot.
He suffered a session whitewash in the 1998 semi-finals with his opponent moving 12-4 ahead from 4-4 to complete a 17-9 victory, and also lost two quarter-finals to the Wishaw man in 2007 and 2011.
But his loss to the four-time world champion this year was probably the worst because of the nature of it in encouraging an opponent clearly struggling with the occasion.
O'Sullivan had sparkled, with breaks of 137, 116, 95, 91, 86, 82, 80, 76 and 55 helping him dominate the first two sessions to lead 9-4.
But missed chances at key moments in the final three frames of the session proved his undoing as Higgins somehow escaped only 9-7 down.

It brought back stinging memories of his defeat to Selby in the 2014 final as a slightly disbelieving Higgins regrouped on a fresh cloth the following day to complete an unlikely recovery boosted by three centuries of his own.
Even in the final frame, O'Sullivan had the chance to claim the victory, but a questionable positional shot ended with jawing a tricky red in suffering a jarring exit that seemed eminently preventable.
"I missed too many vital balls all through that match, important shots I got tight and nervous," O’Sullivan told TNT Sports.
"When you are playing more, and winning more, that is probably what it is, you probably pot those clutch balls.
"That is the difference between winning the big matches and tournaments, you pot those balls under pressure. I missed far too many.
"It’s all about potting the big balls under pressure, and I just didn’t."

4. Lost 17-11 to Graeme Dott, semi-finals (2006)
Another year, and another session whitewash. Amid apparently terminal issues with his cue tip, Dott stretched away to a 16-8 lead from 8-8 in the last four, on his way to claiming the Crucible title in 2006.
It came only two years after he had filleted Dott 18-8 to lift the world crown for a second time.
"I missed too many balls, didn't make enough breaks, my safety was poor and my long-ball potting was awful," said O'Sullivan, who gave away his cue to a young fan following a match that was delayed for 15 minutes to enable him to replace the tip on it.
3. Lost 13-10 to Luca Brecel, quarter-finals (2023)
O'Sullivan, the defending champion from 2022, had numerous chances to finalise the victory, but squandered them all in shipping seven straight frames from 10-6 clear.
He was bundled out the Crucible stage door in only 79 untimely minutes, failing to make a break over 30 in the final seven frames.
It is fair to say, win or lose, The Rocket doesn’t do anything by half-measures in Sheffield, with Luca Brecel claiming the trophy five days later.
Higgins and Selby, grinders to the bitter end, were still negotiating their third frame of a gruelling second session on the other table while Ronnie was trying to make sense of a demise delivered with enough shock and awe tactics to leave onlookers dumbfounded.
"It’s hard to win this tournament if I don’t flow," he told reporters. "There is only so much hanging on you can do at the Crucible. It catches up on you. Eventually, someone plays well against you and puts you away.
"In some ways, it’s a blessing that I didn’t have to carry on playing because it was hard work. I wasn’t really firing."
2. Lost 13-11 to Peter Ebdon, quarter-finals (2005)
O'Sullivan, the fastest player on the circuit, had sped to an 8-2 lead over Peter Ebdon over the two-day quarter-finals, but somehow contrived to lose 11 of the next 14 frames against an opponent unwilling to yield in time.
The scoreline told only half the story, with Ebdon managing to win the contest, despite producing the highest break of only 60 in a match in which his average shot time crawled along at 37 seconds.
Clive Everton, the late celebrated snooker journalist and broadcaster, succinctly summed matters up in The Guardian newspaper.

"In the last eight frames, Ebdon asked for the cue ball to be cleaned 30 times," he wrote. "Excessively slow play, with the intention of unsettling an opponent, is against the rules.
"Referees are empowered to warn a player that the frame may be forfeited. Colin Brinded, the match referee, issued no such warning, but a sizeable body of opinion believed he should have."
O'Sullivan saw the funny side when he recalls the infamous contest that included a 12 break in the 19th frame that took Ebdon over five minutes and 30 seconds to compile - slower than his world record 147 break of five minutes and eight seconds in 1997.
"I think Peter holds the record for the world's slowest break. It is just fantastic. I think we should have a memorial award for him," said O'Sullivan.
"World Snooker should create an award for him titled 'The best worst slow break in the history of the game'. Ebbo would be proud of that.
"It was hard sitting through that. He kept getting the ball cleaned. And took five minutes to piece together 12 points.
"I made a 147 in around the same time it took him to make 12. You think, 'wow, that must have been slow'. Every frame seemed to go like that. I was glad when it was over for me in that match."

1. Lost 10-8 to James Cahill, first round (2019)
O’Sullivan returned to the top of the sport going into the 2019 World Championship, reclaiming the world No. 1 spot for the first time since 2010.
The then-five-time world champion entered the tournament as favourite in a season he also became the first player to reach 1,000 centuries.
"I don’t mind playing him. I don’t mind playing anyone. I know it’s the toughest draw,” Blackpool hopeful James Cahill told TNT Sports ahead of the first-round match.
"I’ve beaten Mark Selby, Neil Robertson, Ding Junhui and Shaun Murphy in the past. I’ve proved I can beat good players."
And so it proved, as O'Sullivan was on the wrong end of the biggest shock in Crucible history.
Cahill led 5-4 overnight and then moved 8-5 ahead in the second session. O’Sullivan, battling a virus, battled back to 8-8, but it was the 23-year-old amateur who held his nerve to reach the second round as the colour drained from O'Sullivan's face.
O'Sullivan - who was 1-50 to win the contest - revealed he was not match-fit.
"I found it tough, I haven’t felt physically great for a while now. I don’t know if I’m carrying a bug or something," he said.
"Some days I’m alright, and some days I feel really shattered and tired. My arms and my legs just feel like lead, and it was a struggle physically.
"Mentally, I just tried to hang in there and see if I could manage to get through the match, but it wasn’t meant to be."
