The age of a person is really important in casino gambling, there are always restrictions for every casino but if you really want to gamble then you may choose to gamble online, you may change your identity there if the website requires KYC then you may use the information of your older brother or your parents as well.

At your age, below 18, you should try some other things than gambling, there are many other better things to do than to gamble. You better study first before getting into a gamble, that would be bad for you if you gamble at your current age.
