What is this code?

What is this code? I see everyone is talking about this. What does it do? Please kindly explain.

they are codes that give you free chests for rewards, you may enter them in the code tab

Thanks bro but where to get them?

you may search threads that cover "gamehag codes" or just "codes", there are plenty of them ,and try them one by one, most of it are already expired though, but there are recent ones

i already used all of them

I think you should take a look at treads. That someone may post it. Don't forget to join discord sever for upcoming code and more!

Thanks bro for the info

You can also search for the monthly and seasonal codes in the Giveaways section!
