Instructions
Have the Sim who is the best cook "Serve Breakfast" on the day of the party. Do not let your Sim go to work on the day of your party. Make all your Sims participate in an entertaining group activity like watching television or going out to the pool. Have your Sims sleep on the couch or bed for at least four hours.
Get a mechanical bull, bubble blowers, a DJ Booth, balloons, strobe lights, dance floor, buffet table, punch bowl, go-go cave, club code thrill light, pool table, television, couches, dining table, toilet, hot tub and pool for your party.
Call the Caterer and hire him for $350 per day. The Caterer will refill the buffet tables and punch bowls periodically during the party. His workday ends at 11:00 p.m., which is when you should start dismissing your guests.
Pick up the phone and choose the "Throw Party" option. Five neighbors will arrive. Do not open the door, even if they ring the doorbell. Within 60 minutes, each neighbor will find a way inside by themselves. If you open the door, they will all come in at once. In "Sims: House Party," it is best to start small by having only one or two guests enter your home at a time. Invite five new neighbors every hour.
Hire a female or male entertainer to pop out of the Fancy Feet Cake Treat. Eat food from the buffet tables if the guests are not already helping themselves. They will follow your lead. Make all your displeased guests leave and invite new ones. Unhappy guests pull down the mood rating.
