Having age restriction in online gambling and real life gambling is really important, kids should not be in the casino because that is so wrong for kids to be exposed in gambling because they are still not thinking so well. There are so many things that kids may do, more productive, more useful and knowledgeable, they may read some books, watch movies, bonding with family, play toys. That is greater compared to gambling.
The government can restrict the ages of playing gambling in real life casino. Still, I don't think that they can do the same in online gambling because once the kids using the mobile phone or computer or laptop, they can use it without anybody knows. We know that now, many kids already know how to operate the gadget. They don't have any problem browsing on many websites, including porn and gambling. The only way that we can do is prevent them from using the gadget for a long time, and we need to watch closer beside them so we can know what they do.
