To use a referal code go into your options menu then there should be a list of options with the title of other to the right hand side of the screen on that list there should be a button thats says refer a friend click on said button.

You will be exited out of the options tab and put into the main menu with a yellow-ish box in the middle put the referal code of your choice into the small rectangular text box, press confirm and presto you have successfully used a referal code!

If you are looking for your referal code it should be above the text box that I have mentioned above.

EDIT: The new update added more ways to refer someone the easiest one is at the bottom right corner of your screen a button occasionally saying refer a friend will appear press that and you will see the yellow-ish box that I have mentioned above. when you press the multiplayer icon. After you press the multiplayer icon there should be a button saying refer a friend press that and the yellow-ish box that I have mentioned above will be there.

Feel free to put this referral code into the text box: Y82R-YD5I
