At least seven players have missed the final black on a score of 140: Robin Hull, Ken Doherty, Barry Pinches, Mark Selby, Michael White, Thepchaiya Un-Nooh (twice in the 2015–16 season), and Liang Wenbo in a qualifying match at the 2018 World Championship, after he had already made a maximum earlier in the same match. Breaks above 147 are possible when an opponent fouls and leaves a with all 15 reds still remaining on the table. A break greater than 147 has happened only once in professional competition, when Jamie Burnett made a break of 148 at the qualifying stage of the 2004 UK Championship. Jamie Cope compiled a break of 155 points, the highest possible free-ball break, during practice in 2005. Alex Higgins is said to have attained the same feat by some players.
