There are a few ways to earn free Gems
in Temple Run 2, although understandably the developers make it as hard as possible for you to get them without paying! The first is that you can earn one free Gem for liking Temple Run 2 on Facebook. Also, you can get 250 Coins for following Temple Run 2 on Twitter. Although this isn't going to make a great deal of difference to your overall numbers, every little helps.
There are no cheats for Temple Run 2, as the developers want you to spend your own money on the game. If it was possible to get infinite Gems
, clearly no one would ever pay! The best way to succeed at the game is to practice and play a lot, saving up your Gems for that ultimate run when you need them the most.
