Based on everything that I read so far, this seems like a high risk, high reward affair where you could get rich overnight provided that the luck is in your favor and the site should be willing to payout. Personally, I wouldn't take the risk here even if the site is legit.
Why? Because lotteries aren't worth it unless you play with miniscule amounts and since there are far better alternatives that improve your chances of getting rich overnight.
Or you have so many tickets you would probably win something nice, but I wouldn't do it too.
I don't know what risk you're talking about guys? A single scratch card costs £1!

Of course, I'm not saying that for someone this might be a large amount and they might assess the risk differently. But then they shouldn't even visit the casinos section, because many casinos won't even accept such a small amount as a deposit.
