We can consider that it is wrong for the kids who are playing gambling whenever there's already a money involved . They do and play it as a game not the way as it should be and much better to avoid or do not let play some card games or any gambling related games because i assure you that if ever they found it very entertaining they will start to try something new which is there would be a money that is involved .
So better to not introduce them in gambling as long as they are not responsible enough , i mean as long as the kids are not in the right age we should not teach them some games related to gambling . This should be the fault done by adults not by the innocent kids . If we would educate them right they are going to do this things .
