The 5th Doctor doesn't get released in the game until next Thursday so by entering you could get him way before anyone else!
The other 10 codes will be available tomorrow via our Twitter account, @GallifreyTimes, so make sure you are following us!
The question for today's codes is below:
What are you most looking forward to in Series 8 of Doctor Who?
To enter, simply comment on this article with your answer (minimum 50 words - to prevent short answers) and we will randomly choose ten entrants to receive a code!
Your answer must be submitted by 20:00 BST today. Any answers submitted after this time will not be included in the giveaway. Winners will be notified within an hour of the giveaway closing and your code will be sent to you sometime tomorrow (Tuesday). Any entrants found to be submitting more than one answer will be disqualified from both this giveaway and those in the future.
We wish you the best of luck! (Oh and don't forget to read our review of Doctor Who Legacy here!)
