Hi! You make money a couple of different ways- you go to the Widget factory to 'work' every 6 hours, play tictactoe or rock paper scissors with people (you only get $ if you win or tie), and you can visit your friends- you get more $ if you leave a message instead of doing to other things.
In order to get more rooms in your apt you have to level up but earning points. You earn points the same way you earn $. To change the walls or put in furniture you have bought or rearrange stuff you click on the Edit button.
I have kinda gotten burned out on Yoville since getting into Farmtown but still play occasionally.
