Hi Rebecca,
I had occasion to watch some of this show the other night - and I must admit, I was fascinated by the business model they use.It does seem like a licence to print money.
1.As a prospective caller, you face two random lotteries - The first is to be selected to be placed on hold. The second is to be the number put through to the studio from all the callers they have on hold, selected randomly. ( 10,50, 100, 200?)
2. Each call you make will cost you 75p, irrespective of whether you are successful in being placed on hold, or even more rarely getting through to the studio.
3. The presenters are very good at ratcheting up the excitement, with "call rushes", countdowns, and, of course, big prizes of �40-�60,000.
4. The puzzles, particularly the mathematical problems, are deliberately ambiguous, and any one puzzle can have multiple "correct" answers, depending on which interpretation of the question the producers have selected for that night... so as a caller, you face a 3rd lottery, which is to get lucky identifying which particular solution they have decided to use.
5. If you do plan to play, it would be worth your while watching it from the beginning and noting all the wrong answers... in the time I was watching it, at least 5 callers gave answers which had already been dismissed as incorrect!
