Apparently, Temple Run is a "runaway" success on Android as well as iOS. The amazing little game that has already been downloaded 45 Million times on iOS over the last 7 months, just launched three days ago on Android. In that time-frame it has already been downloaded over 1 Million times. Furthermore, besides the high download rate, the game is also garnering high marks and praise. Over 46,000 people have already commented on it and it's average rating is 4.3 out of 5 stars.
You can grab the game for free on Google Play, although sadly, it does have some compatibility problems with the Droid RAZR and the Droid Bionic, so keep that in mind. Hopefully, the game devs are working to change that.
