Help your friends get Santa coins

Or you could put 3-6 brown houses somewhere and leave them for the coin fiends.

It's not enough. 3 houses is good for 1 visitor to get 3 coins. If you've got 80 friends (and you don't like farming), you need to leave them untapped (to be good to your friends).

Also, if you don't log on for an hour, the brown houses won't be available since they were clicked by other friends.
