You know the ones…

what is the capital of england….
what do you call the big clock in London…

That sort of thing. Well if your a CSI viewer you'll know they have a really stupidly easy question at the end to win pots of cash, ring in now only £1.50 per second calls last 3 days etc etc.

You can send in a postcard or enter online for free. My neighbour did last week and got a letter telling her she'd won £5k!!!! 😀 Cheques in the post in next 28days. Phone call from CH5, name on TV next night as a winner.

I always had them down as a bit of a con, but hey ho, in it to win it etc..

Just about any competition like that (including the ones you get on food packets, drinks, newspapers) should have a free entry option. So the competition on a tin of beans should have the option to enter without buying the tin of beans. "No Purchase Necessary". Otherwise its a lottery, and not just anyone can run a lottery. Strictly speaking the question should be difficult enough to get wrong (and a good proportion of people entering should actually be getting the answer wrong) otherwise its a game of chance – a lottery, rather than a game of skill.
