Long-running vehicle for blue-comedian-turned-good Jim Davidson to lark about and make silly voices.
Hot to pot

Host Jim Davidson, a UK stand-up comedian by trade, guides three teams through the rounds. Each team is made up of a contestant and a professional snooker player. In the first round, Red Hot, the contestants answer three rather easy questions in order to win time for their snooker playing partner who then has to "pot as many balls as they can" of the ten reds available on the table. The team who scores the least in terms of potted balls leaves the game.

At this point in the show, the leaving contestant gets the chance to perform a trick shot for a consolation prize. The trick shots, set-up by co-presenter and professional snooker player John Virgo, took a life of their own and a few (mostly awful) shows with purely trick shots were to appear in later years.
Pocketing profits

The cleverest round, Pocket Money, involved the skills of the contestant and snooker player rather more. The snooker player would try to make a continuous break, scoring ten times the normal snooker value in pounds (so a potted 7-point black earned 70 pounds). When the player did not pot a ball, or committed a foul, the contestant would have to answer a question. Each ball colour related to a particular category of question (yellow was The Past and so on).

The pockets on the table were coloured with the six snooker colours. If a coloured ball happened to be potted into the correct corresponding pocket, its normal money value would be doubled. For example, the pink usually earned £60 but if it was potted into the pink (top right-hand corner) pocket, it would earn £120. Virgo would often shout out e.g. "Double pink!" to alert players to the possibility of doubling their money.

Make or Break

The player earning the most money at this point went on to play Make or Break. The contestant answering up to five questions correctly allowed the snooker player to remove up to five red balls from a six-ball pack of reds. The snooker player would then have the remainder of the 90 seconds (whatever the contestant had not used in the question and answer section) to pot the balls that remained. The normal snooker rules applied, so after potting a red the player had to go for a colour before attempting to pot the coloured balls in sequence.
John and Jim cue up for a quick frame

The best thing about this final round was that the results were often very varied. Sometimes the pro would make a really good start and then spend the last 30 seconds trying to get one ball in. Sometimes the player would be able to win the star prize even though there were three reds still to pot before going on to the coloured balls.

A spin-off series, Big Break: Stars of The Future, featured teenage players and contestants with virtually the same rules (a bit more time here and there, and the kids only keep 10% of their winnings because the rest goes to their school).
Game over

The show ended around the same time Davidson's other show, The Generation Game, did. Perhaps the show was running out of legs, maybe indicating why the BBC tried out Full Swing in 1996, a golf show in the same vein as Big Break and produced by the same John Burrowes. Although Full Swing wasn't recommissioned, nevertheless Big Break was one of the most popular shows that the BBC had done in the 90s.
Key moments

Virgo's "it's foolproof" trick shots.

"Pot as many balls as you can"

"We ask you to make your break".

"The time will start the next time you strike the cueball".

"Hit it quick!"

Davidson and Virgo used to sign off each show with, respectively: "Say goodnight, JV!" - "Goodnight, JV!"

Many years ago, the BBC had a rather tacky quiz called Pot the Question. Hosted by Stuart Hall, snooker players would pot balls on a snooker table to earn the contestants questions. Big Break, invented by Terry Mardell, is a similar kind of idea but with a very different tone and has been far more successful.
Theme music

The theme music is The Snooker Song, composed by "Mr. Wombles" Mike Batt. It is sung by 1980s pop sensation Captain Sensible. It was originally written for Batt's musical The Hunting of the Snark in which Captain Sensible played the role of the Billiard Marker. Mike Batt also did the theme for Germany's biggest gameshow Wetten Dass...?, dontchaknow.
