  • Head to Settings by pressing the Settings Icon on the game screen
  • In the newly opened window select Code Redemption
  • Input our code exactly as we shared it

Broken Code!

Don’t worry this is typically down to one of two issues. Either the code has expired and we haven’t moved it over yet (sorry…). Or it isn’t being input correctly. Don’t forget that codes are cap-sensitive so they need to be written into redemption the exact same way that we shared them!
