There are also flying ones which are really fun too, listed my favorites below. Best of all most of them are free! Though if you like them, support the developers with an IAP (in ad purchase). Please, please, please check out Light the Night below! Sorry Android users most of these seem to be for iPhone with the exception of Temple Run Brave/Temple Run.
My favorite. Has a wonderful color palette, much more rich and vibrant than Temple Run. Updated regularly and they have listened to fan feedback as well. Designed for both iPhone and iPad. Don't forget to watch videos for free coins!!!
Found this one to be very fun, but they are big on an in app purchase (IAP) for the Pro Version. Not sure if that is worth it, but they did just add a lot of new for the Pro users. End of the world theme. Very colorful and fun watching the world degrade the more you play. Will give a Pro shot when I earn my next giftcard. Designed for both iPhone and iPad.
Also, here is a link to the original Temple Run. It is FREE! Android and iPhone/iPad
