Max.org - Coin Run

In YoVille, players can get "coins" by visiting friends. You can visit friends by clicking their avatars at the bottom toolbar.

When you are taken to a friend's room, you will be shown 6 options: Kiss, Joke, Send Free Gift, Dance, Fight and Message. You will usually get 15 to 20 coins per visit when completing an action. Some players prefer to select the Message action as it is quicker to finish. It is a norm in YoVille to leave "Coin Run" or "CR" for this purpose.

In addition to the 6 options, you may pick the Exit button instead. Then you can click the View Guestbook icon at the bottom right corner, and leave a gift to your friend from your inventory.

You can not earn coins indefinitely by visiting friends, however. There is a daily limit of 400 coins for visiting 25 different friends.
