Ubisoft announced its latest initiative to celebrate the company's 30th anniversary, '30 Days of Giveaways'. In it, they'll give away something everyday (including games) for 30 days. It started yesterday, November 24, and will continue till December 23. The first gift was Rayman Classic for mobile.
To claim your gift, you need to visit the official page and login to your Ubisoft account. Then click on the calendar looking, square shaped button to reveal your gift. It's a lot like opening a Christmas present, if you ask me. So, go and get your gift!
