Of course no. Underages children shouldn't be allowed to gamble.It's not expected that our future generation became gambler. Allready bans players from gambling advertisements in some European countries. To protect them I think  no road should be left open for them to engage in gambling.  And for this, when you allow children to be connected with mobile or technology, it is necessary to monitor them properly. And if parents are aware of this, it is possible to protect children to being a gambler. Yes an overage people can take gambling as a entertainment but it's also not good that being addicted in gambling.
