If you like the endless runner game, Temple Run, you will have come across Temple Run: Oz.
It is a paid game, similar to the original Temple Run, but with better graphics and based on the Disney movie, Oz the Great and Powerful.
Run though forests, fields, the Yellow Brick Road and fly in a hot air balloon. The game has different environments which changes as you run for a certain distance, and each environment has a different obstacle, including the mischievous flying baboons, evil trees, and collapsing bridges. You can upgrade various power-ups by collecting coins.
And as a bonus for downloading the game. you will get 1500 coins for free. That is $.99 USD worth of coins to buy power-ups and other items.
The game is a 50 MB download and should run on all iPhones, iPads and iPod touch devices running on iOS 5 or later.
Temple Run: Oz normally costs $1.99, but you can get it for free for a limited time from the iTunes Store.
This is a limited time offer, so get the game while it is still available for nought.
Note: Even though it is (normally) a premium game, it still contains In App Purchases, but they are completely optional.
