The IGN Free Game of the Month is Trivia Crack (Ad Free version) which costs$2.99 on the App Store.
For those who are new to it:
Trivia Crack is the international smash hit game that pits friend against friend in different categories to determine who has the most trivia knowledge. Each of the six categories (Science, Entertainment, Art, Geography, Sports and History) has a corresponding character, and the game is won by being the first to obtain all six.
The game is designed for both iPhones and iPads. It also offers a nice quick-fix game for your Apple Watch which I have been wanting it for quite some time.
You can get a free redeem code on IGN’s website here. Enjoy!
