БрейнТизер: Британское телешоу-головоломка

British television series
the type of puzzle

BrainTeaser was a British game show based on the original Dutch format of Puzzeltijd (English: Puzzle Time). The show was broadcast live, with phone in viewer puzzles being announced and played during the show in addition to the studio game. During its run from 5 August 2002 to 7 March 2007, it aired on Five Mondays to Fridays, usually for an hour around lunchtime, and was fronted by various presenters rotating with one another (most notably Alex Lovell, who was the only presenter to front the show for the entirety of its run). Beginning in August 2005, a version of the show that exclusively focused on viewer participation was broadcast in a four hour long block on YooPlay TV (A joint venture between Five and YooPlay) every day after the Five broadcast, as part of a thirteen week trial. Channel 5 suspended the programme on 8 March 2007 after it was revealed that the production company, Cheetah Productions, had misled viewers regarding winners of the viewer puzzles (which were entered using a premium rate phone number). Actions included publishing fictional names and presenting a member of the production team as a 'winner'. On 26 June 2007, Channel 5 announced that the show had been cancelled after 1122 episodes after media regulator Ofcom fined the channel £300,000.

Initially, the show was presented by Alex Lovell and Craig Stevens, who alternated with one another week by week. They were joined later in the show's run by Rachel Pierman. After Stevens' and Pierman's departure in early 2004, Lovell alternated with Jonny Gould. At the end of 2005, Gould left the show and was not replaced, leaving Lovell the sole presenter apart from occasional breaks (which were usually covered by former regular host Craig Stevens).

The most recent format ran from 15 November 2006 until the show's suspension and its eventual cancellation. In each show, there were four contestants, all of which play the first three rounds. The lowest scoring contestant is eliminated after each of the third, sixth and eighth rounds, so that only one is left standing for the Pyramid. Except for Word Wheel and the final Pyramid game, all rounds are on the buzzers, with the opponent given a chance to answer if the player who first buzzed in answers incorrectly.

Words of eight or more letters are partitioned into four or five pieces, rearranged and presented to the contestants, who must unscramble them. Only five points per correct answer are scored in this round. In all other rounds, each correct answer scores ten points.

This is a general knowledge round. Contestants must identify something (a famous person, TV show, film, place, etc.) from the clues. First the category appears, followed by four short clues revealed one by one. If a contestant buzzes in but fails to give the correct answer, the clues continue to be revealed. When all players but one have attempted to answer it, all four clues are revealed for the remaining player.

Three letters are given. Contestants must give a word that contains the three letters in the given order. This is similar to the main game principle in Catchword and the In a Spin round of Masterteam. However, there are two differences:
The first given letter need not be at the beginning of the word. The second and third letters may not occur prematurely, even if they also occur in the correct sequence. For example, given the letters C L O, the word "colour" is not allowed, since an O occurs before the L.
After the end of Trio, the contestant with the lowest score is eliminated, and the other three contestants continue, with their scores set back to zero. For the first few days under this format, the scores from the previous rounds were retained at this stage, and reset to zero only after Word Wheel.

The players are shown a word with the letters in the wrong order. Letters drop one at a time into the line below in the correct place, until one contestant buzzes in with the right answer.

The players are shown a word and three possible definitions. The players must buzz in and select the correct one. If the player gets it wrong, he or she is frozen out and that definition is removed. The remaining two players are allowed to buzz in and offer one of the remaining definitions. Often, there is a common theme to the definitions given for a word. The principle is similar to Call My Bluff or the board game Balderdash; the words are generally less obscure than those featured in these games, but still unusual enough to challenge most players.

A word of at least ten letters is shown in the correct order, but on a wheel so that the letters are arranged clockwise in a circle. The contestant who buzzes in with the answer receives 10 points. From then on, play moves from left to right with no buzzing, beginning with the player who identified the word, and each player in turn must offer a word at least four letters long, and they receive one point for every letter of the word. For example, from RATIONALLY the players could offer TRAY for 4 points, TRAIN for 5 points or RATION for 6 points. For the first few days of this format, there was an additional twist: Any player who failed to give a word when his/her turn comes round, or gave an invalid word, was frozen out for the rest of the round. Should all players be frozen out before the end of the round (this happened only once), a new word would be given and all contestants would be back in play. Now, all three players who reach this round remain in play throughout the round. One contestant is eliminated after this round, so that two remain. The scores are again set back to zero.

This is a general knowledge crossword game. The computer randomly selects the first clue to be presented to the contestants. The player who correctly answers each clue then chooses the next clue to be solved. If neither player can give a correct answer, the answer is revealed and the next clue is chosen randomly again. Prior to 2005, this was not a quick fire round. Instead, one player had control at a time, starting with the player who scored the most points in Scramble. The player who has control had the first attempt at answering each clue, and control passed only when a player failed to answer correctly. If neither player could give a correct answer, the control stayed with the second player to whom it was offered.

Contestants must find a word with the given number of letters and the given first and last letters.

Before the change to the most recent format, only two contestants played at a time. The first three rounds were Scramble, Crossfire and Trio, and these were played in two heats, therefore all four contestants played these three rounds. The winner of each heat went into the "semi final", comprising the rounds Clued Up and Wordstorm. (The "final" is the solo Pyramid game.) Prior to 2005, Wordplay was played instead of Trio, and Wordstorm preceded Clued Up in the semi final. Wordplay had two differences from the round in the more recent format:
If one contestant buzzed in and failed to give the correct solution, only one more letter in the solution was revealed for the other player. The letters did not disappear from the original anagram as they were revealed in the solution as they did more recently (this does not directly affect the gameplay).

In light of the ICSTIS investigation of the use of premium rate telephone numbers in various interactive British television programmes as part of a phone in scandal, Cheetah Productions (a division of Endemol), who created the BrainTeaser format, admitted that some of the show's contestants were fake. On 8 March 2007, Channel 5 resultantly suspended all shows involving premium rate services, claiming they knew nothing about the scam. However, a simple procedure checking daily winners would have easily identified the fraudulent activity instantly. Channel 5 later admitted that the channel's senior producer was informed by Cheetah Productions that several winners had been fake. The channel ignored this advice and continued to broadcast the show until the ICSTIS investigation was concluded. During this time, Avon and Somerset Constabulary reviewed the reports from Channel 5 and the ICSTIS to see if there were any allegations or evidence of criminal wrongdoing contrary to the Fraud Act 2006. Once the ICSTIS investigation was completed on 26 June 2007, Ofcom handed out a record breaking fine of £300,000 to Channel 5 for the phone in scandal. The channel cancelled the show, after 1122 episodes. The Ofcom report found the use of fake winners had begun as an expedient to help the continuity of the live format; as such, fakery was not used frequently until 2007 when with the introduction of the Quickfire format to the viewers' quiz led to time constraints on sourcing contestants becoming more pressing. A system was in place that labelled callers Blue, Red or Green; these represented a caller with a correct answer ('blue'), a caller with a wrong answer ('red') or no winner could be found ('green'), in which case a fake name or staff member would be substituted. Endemol claimed their original intention when using 'green calls' was to select a genuine winner after the show; however, this only happened once. Both Channel 5 management and Endemol UK have subsequently apologised.
