In this current age and Time, it has become extremely hard to keep kids away from something that is widely done like gambling we just have to educate the kids on the fact about gambling and how hard it is to get out of gambling once you become huck to it, and to avoid that kid's needs not to be greedy and should not stake money on games unless if the regular computer games.
The internet is part of the major reason why kids get involved in gambling, we live in an era where the internet is stormed and dominated by teenagers and casino owners are taking advantage of this using this means to lure them into gambling, after seeing their favorite celebrity or model advertising a casino site and displaying fake wins what would you expect from them. They should be shielded from this lifestyle instead of trying to entice them to get into it. Awareness programs aren't enough to keep them away, they must also be restricted.
