How to play video game secretly?

So I'm not allowed to play a game but I really want to play it so I'm planning on buying and downloading it on my xbox. My problem is that my brother will see it on the console when he goes to play mincraft and my parents might recognize the game when they see me playing it. How can I play it without getting caught?!

Try to do a search on Google, maybe that will work out

Well let's see. From your lack of information given and your obvious need to play this game, you should probably:
A: Wait to play the game if you will be allowed to eventually. If you just want to play single player then you can definitely wait.
B: Install the game, play it, and uninstall it every time you play. I'm not sure if this would delete your saved data though.
C: Just play it anyway.

First world problems.

I doubt there's any way to hide a game. You're just going to have to risk it, I guess. That, or don't even bother trying. Depends on the risk and how bad it will be if you're caught. Hopefully you're smart enough to think it through.

Kids these days lol

Get someone to buy it for you from gamestop so you can hide the game in your closet or something when your brother gets on.
