ciao 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 te pause your game.)
Scroll through all the cheats. te might not have every cheat bacause te don't have the right game. To exit the cheat bar, (did te know that "exit" is a cheat code?)type in exit and press enter. And BOOM! te have awesome cheats.

Happy Simming!
