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

Happy Simming!
