Normally gambling is only for adult but the problem of bitcoin is anonymous so they can't stop kids from gambling.
but i don't know why playing dice for example is like a kid game :p there is some games is not for kid like casino and others.
maybe it could damage the kids mind when he will interact with adult in gambling games.
I think they can play dice with a board of snake and ladder game, but with a dice game that is also money involve for kids, that is already that good for kids, so for those parents who is out there that didn't want to make their children addicted into it, supervise them so that they will not get hooked with it.
