Starting Tuesday, May 29 at 11AM PDT, Twitch will air daily eight-hour classic Doctor Who marathons on TwitchPresents. That’s over 500 episodes of Doctor Who over seven weeks!

To add to the fun, Twitch tapped Muxy to create the Doctor Who Watch to Win Extension. All you have to do is opt into the sweepstakes and watch the show to be entered to win Doctor Who prizes.

Just watch for 10 minutes and you’ll get a raffle ticket, which will enter you to win weekly Doctor Who prize packs and a grand prize trip to London Comic Con to meet the Doctors! Enter up to 5 times per week.
