Hi, Sometimes developpers give promo codes to download their games for free. My question is how do we use them?
On Itunes go to the Itunes Store scroll all the way down and click on 'Redeem' under 'Manage' Put the code in and you'll get a free copy of the game. Always remember not to say what code you've get and never say thanks in the thread (being sarcastic, just lots of people do this, take a code and dont say thanks/or what code they've used !)
And on an iDevice, open App Store and the featured tab, then scroll down and press redeem. Type or paste the code and then sign in and it'll begin to download soon.
