I Have found online few hack tools that probably work but in the middle of the hack it asks for an activation code and then I got redirected to an offer page which even if completed it never gets me to the conclusion and no activation number is given to me.
So I decided to pay for someone to develop the tool so I can get free gems for my clan members and myself.
Thanks.
