Mode switch:

Hidden food:
There is more than just the food you can make. For example, there is food that give your skills a boost, food that helps you in love (romance Sims only for their goals), and food not in the list. For example, you can make a pizza.

Easy money:
When you need some money and own a "Defective Arcade Genie Lamp" you can keep making wishes and you will get money eventually. However, the genie can also cause fire and make all the characters in the area of the lamp to pee themselves if you make him mad. When he is mad he will come out of his lamp with red colored smoke beneath him. However, if he is giving you something good the smoke will be purple or pinkish. It is best to perform this when you first get a house so that you can get your money and not risk losing any items you have purchased. Note: If you talk with the genie, he gives you small advice and hints occasionally.

Forced friends:
If you need friends, get a Hot Rock Hot Tub, or move to Tranquillity Falls where they already have one. Invite over who you want to be your friends and get them in the hot tub. Then, put objects around it so they cannot get out. Leave them in there long enough and they will become your friends. Note: Get out before your hunger goes all the way down or else they will die.

Sick meal:
With any meal you make using Llama, no matter what the effect, any Sim that eats it will vomit.

Energy boost effect meal:
Dangleberry, Yogurt, Strawberries and Cherries; or Ostrich, Eel, Strawberries and Mangosteen (expensive but works the best).

Avoid being fired:
If you accidentally miss your ride to work on your second day of missing work, before it says you have been fired, quickly find another job by looking in the newspaper or the Internet. Once you have avoided the call to get fired, you can change back to your previous job without being demoted and getting deducted skill points.

Raising motives:
To raise your Power, Fun, and Comfort at the same time, power nap on a couch with a television or radio on nearby.

Unlocking clothes:
Get your Sim's relationships to 100 with everyone. Every time you raise another relationship to 100, you will unlock a new article of clothing.
