Here are the steps: 1. Go to Settings of Temple Run. 2. Put it on Tutorial mode. 3. Play Temple Run on tutorial mode. 4. When it reaches the first turn to the right, swipe 3 times very fast to the right of course. 5. Then there. No obstacles or anything. 6. If you wanna end the game swipe to the right 2 times then the monkeys will eat you.
If you activated the advertisements that appear in Temple Run to get more coins, and now want to get rid of them, you can do so by going into Settings on the home screen, then General, then Date and Time, then set it years into the future (5 should do it).
The adverts are set to disappear eventually, and this will speed it up!
On Tutorial Mode, when it says slide (on the second time your sliding your finger) you will slide your finger twice for a never ending path. The only way you die is if you tap to into a wall then the monkeys will get you.
To run for ever you turn on your tutorial, than you go in and play the game and than when it says to swipe. Instead of swiping once, swipe twiceand than you can just set the iPhone or iPod or iPad down and just let your person run forever.
NOTE: These codes have been reported to only work on version 1.3 of Temple Run, also possibly only on jailbroken devices where you can get the keyboard to appear (allowing you to enter the cheats). There are no other cheats for Temple Run, so if you cannot get the keyboard to appear on your version, there is no way to get these cheats to work for you.
The original cheat was to unlock invincibility and additional characters, using the codes below while on the Title Screen:
