Roblox is full of things to do and, as a result, there are tons of places/games to look through. Occasionally you may find some that you enjoy more than others and may wish to favorite them to be easily found later.
To favorite a place, start out by viewing its details page. There, simply click the star icon under the Play button. The star should change from an outline to filled-in indicating that it is now a favorite! To unfavorite it, simply click the star once more.
Once a place has been favorited, you can quickly find it above your feed and below your Recently Played games on your Home page or by selecting the My Favorite filter on the Games page.
