I have a kindle fire hd. For money cheats I log into the party boat for neighbours.
Go back to one of my houses, open the furniture store and go to social furniture.
I have seven neighbours so I get the item with the most neighbours I can have which in my case is a record player. Fill as many houses with them (they cost nothing by the way) and then log out of Facebook. To do this go to the ... tab and click the Facebook icon and then log out. Then you go back to your houses that you have filled and sell them all. For the record player you get over a thousand simoleons for each one you sell. You must remember to log out of Facebook though otherwise they will sell for nothing! Hope this helped! It will definitely work for people with kindle fire hd. Not sure about just the kindle fire though!
