This is perhaps the easiest and the quickest way to lose your money.
I simply gave the option to the OP if underage then answer is no. And if above 18, and have some pocket money left then can try the risk, if make money you can go and if you lose that money then forget the trips and all. Then you have to sacrifice it.
Lets not look upon the age instead the reality of the outcome , Look he is aiming to earn legitimately but he was looking for illegitimate option?
Gambling is not the right way looking for income instead this is for fun and the win will only a bonus.
