Fast Simoleons, Genuinely works in The Sims FreePlay

1. Log into the party boat part.
2. Go out then back into the party boat so that you get your NBRs, you will see them at the top by your simoleons.
3. Go to a house or an empty lot.
4. Go to the store and select I think the third tab along, the one with the NBR picture on.
5. Depending on the amount of neighbours you have, select the object you can buy. For example if you have three, you get the swing.
6. Repetitively buy the object and place them down on the property.
7. Pick them up and put them in your inventory.
8. Log out of Facebook through the sims.
9. Go to a property, place them down and sell them.
This actually works. I get quite a lot from them but it takes sometime.
Hope this helps!
