I don't think gambling was made for kids. They have better things to do than bet on this kind of game. Gambling games are for adults that have total responsibility over your own acts and know how to spend their money.
I also do not think that gambling is made for kids because that can end up being bad for them they need to learn how to control there money and not spend it on gambling.
It is better for your kids to not gamble because if they will there are going to gamble if they are older as well.
