A minor is not allowed to gamble. So if you fall under the age of 18 do not try first. Because your account will be useless and in case you have won and they know you are not an adult, it would be forfeited.
You can submit the documents of your friend or relatives for verification. So they can be deceived and pass KYC without any problems.
This is a Scam, if you get caught, you will have serious consequences, at least blocking the game account.
If any minor uses his adult friend/cousin/relative to pass the KYC, this is morally not correct. Although the gambling site may not be able to trace it but it is not good for the minors to play gambling. They are not mature and can misuse the funds of their family.
