I was on the lottery website earlier buying a few Thunderball tickets and had a little bit of money left over so had a go at a couple of the "instant win" games as I do occasionally when I've got a bit of excess left on my account.
Of course, I now have none left 
but it made me wonder how many people really win on these things. The top prize on some of them is massive but if I ever win it's more often than not just the price of the game. The most I've won was £20.
So... have you or someone you know ever won a significant sum on the Instant Win section of the lottery website?!
