The Favorite Button
Do you love a particular hat? Do you really like a place you just visited? Favorite it!
For most types of items, you can select a gold star as shown above to favorite it. You can then find it again easily in the favorites section of your profile. Favoriting a place is also very useful. Why? Because you can sort the Games Page to show your favorite places, in a nice, big list. This list will also show how many players are currently in the game.
