Third party software consists of unapproved apps that manipulate gameplay. By altering game functionality, third party software aims to provide unfair advantages while potentially putting accounts and privacy at risk. 

Third party software includes:
  1. Hacks, “mods”, or programs that unfairly alter game functionality
  2. “Bots”, or gameplay automation services or scripts
  3. Any other programs that aim to modify or provide unearned progress
Any use of a bug or glitches in game system, ratings and level design etc. by a player to their advantage in a manner not intended by the game's designers is also classified as a form of cheating.

Please remember that using all listed above will cause blocking your account without the possibility to recover it! Even if you used it "only one time" or "it's my friend who did that, not me".
