You can visit your friends in the game and look at their Town, houses and other locations. To visit a friend, find the friend’s picture in the friend panel at the bottom of the screen and click it. The game will take you to your friend’s town. At the top of the screen, you can choose the location you want to visit, such as Anna’s house, winter or tropical map and Lumio's house (if your friend has already unlocked them).
To return to your own town, click on the “Go home” button in the bottom right corner of the screen.
