In its first four days since launch, Imangi Studios’ runner app Temple Run 2 for iOS raked in 20 million downloads in four days, with six million downloads on launch day alone. Also, the game skyrocketed up the charts to the No. 1 spot on the top free apps chart in a matter of eight hours.

The Raleigh, N.C.-based studio pushed Temple Run’s brand presence through licensing partnerships in 2012, which included Temple Run-branded apparel, digital comics, arcade machines, sleepwear and card and board games.

Founded in 2008, Imangi Studios’ original Temple Run has been downloaded more than 170 million times to date across the Apple App Store, Google Play and the Amazon marketplace. Other notable titles from the bootstrapped developer include Harbor Master and Disney Pixar movie tie-in, Temple Run: Brave.

According to our traffic tacking service AppData, Temple Run 2 is ranked No. 1 on both the top free iPhone and iPad apps charts, No. 3 on the top gross iPhone apps chart and No. 7 on the top grossing iPad apps chart. The game is scheduled to release on Android later this week.
