I'd love to play it to be honest. Even it's possible to win a lambo with a penny, I think the chance is extremely low and the house don't want to lose their money, so a lambo for gambler would be about two or three lambos for the house. Is this unfair thing?
The problem is that such raffles depend on the honesty of the organizer. The organizer decides to take all the money and run away, but you will not find it. And then no matter how much you could buy houses for one lambo.
