Snooker plusとは 意味・読み方・使い方

Snooker plus (sometimes spelled snooker-plus) is a cue sport based on snooker. The variant was created by Joe Davis, who added an orange ball (8 points) and a purple ball (10 points) to the set. The idea was that this would increase the maximum break from 147 to 210, and so help to attract a greater audience. At the end of the frame after the six normal colours were potted in their usual order, then they were followed by orange and purple. If the frame ends in a tie, then the purple was respotted on the black spot. The new format was introduced to the public on 26 October 1959 at the Burroughes Hall, London during the News of the World Championship. The variation failed to catch on, and the extra colour balls necessary to play the game are not available from any major supplier.
