Hey Simmers!
Okay, my friend's friend showed her a cheat that reveals EVERY SINGLE CHEAT!
It's really simple accually, just bring up the cheat code bar (ctrl+shift+c) and type in:
help
Press enter.
(I recemend you pause your game.)
Scroll through all the cheats. You might not have every cheat bacause you don't have the right game. To exit the cheat bar, (did you know that "exit" is a cheat code?)type in exit and press enter. And BOOM! You have awesome cheats.

Happy Simming!
