I seen a kid maybe 7 or 8 drop about 4 or 5 dollars into one of those operate a crane and catch a prize machine. That is a gambling on the odds deal.
Kids sit in these game rooms and drop loads of money into a machine to beat the odds.
Lottery is entertainment too.
Old enough to have money old enough to spend it.
Kids make enough money they are taxed on it too even if they are a minor. Should have the same right as anyone.
