In just four days Temple Run 2, the follow up to the incredibly popular endless runner, has garnered over 20 million downloads in the iOS App Store alone. Not only that, but despite being free, it’s already become one of the highest grossing apps because of in-app purchases. People sure do love buying little knick-knack things.

To show just how incredible Temple Run has been for Imangi Studios, an app like Angry Birds Space amassed 10 million downloads over a three day period—and that was across multiple platforms. Temple Run 2 hasn’t even hit Android yet

This is one of those cases where a simple (and old) idea was executed to perfection. There’s nothing particularly innovative about either game, but they’re entertaining as heck, and perfect time wasters.
