Nearly three quarters of people in the UK now do some sort of puzzle, from newspaper crosswords and coffee-break teasers to puzzles in magazines and even taking part at home in TV shows like Countdown on Channel 4.
A MORI poll conducted to mark the launch today (Thursday November 19) of a new puzzler magazine, Carol Vorderman's Puzzle Challenge, also found:
One in three women in Britain spends more time doing PUZZLES than making love to their man.
And nearly half the women who do puzzles every day devote more time to solving them than to sex.
- Q If you currently have a partner, lover, boyfriend or girlfriend, which of the following do you spend more time doing?
It is not just women who are hooked on puzzles. One in four men also spend more time wresting with puzzles than between the sheets with their partner.
But women are found times more likely to do puzzles IN bed than men are.
Half of those who tackle puzzles do them every single day.
While most spend less than 60 minutes a day on their hobby, a fifth admit devoting more than a hour on them every day.
That is more time than the average women spends preparing meals in a day.
People in the North of England and Scotland spend more time doing puzzles than Southerners.
Even youngsters are mad on puzzles - 75 per cent of 15 to 24 year olds do puzzles. More than 25 per cent try and crack a puzzle every day.
- Q How much time do you spend doing puzzles?
Pollsters also asked people where they do puzzles. Nearly a quarter tackle them while they are watching TV.
One in 12 people solve their puzzles in bed - that's the same number who do their puzzle-solving in the kitchen. The sitting room is still the most popular place: 62 per cent do it there.
A third of people who admit they do puzzles on the loo spend between 38 minutes and an hour there.
Other unusual locations include the garden shed and a lecture theatre.
Only one in a hundred do them in the bath and just four per cent, mainly people who live in the south, solve them on the way to work.
But more than one in ten admit they find time to do puzzles at work. Men are three times likely than women to do their puzzling in their boss's time.
- Q Where do you normally do puzzles?
MORI also asked which celebrities would be good at puzzles. Countdown star Carol Vorderman comes top, followed by Newsnight inquisitor Jeremy Paxman and PM Tony Blair.
Anthea Turner scored well but only seven per cent of people thought Cilla Black and Coronation Street's Vera Duckworth would be good at puzzles.
While soccer hardman Vinne Jones, Gladiator Wolf and Posh Spice Victoria Adams were branded as flops at solving puzzles.
- Q Which of the following people do you think are most likely to be good at doing puzzles?
Carol Vorderman said: "I know from presenting Countdown that people in Britain love puzzles and this survey has proved it.
"It also shows that it is not just old people who do them. The poll has revealed that lots of young people and working mums are regularly doing puzzles.
"I also wanted to find out how much time people spend of puzzles and where they do them. The results were an eye opener. My idea of heaven is to relax in a hot bath and do a puzzle".
Carol wanted to bring out a puzzle magazine that would appeal to all sorts of puzzle fans.
So each puzzle in her new magazine comes with Carol's Challenge - a time to beat and also a difficulty grading.
Between November 6th and 9th, MORI interviewed a representative sample of 2,029 people in Great Britain aged 15 and over.
