Every time you explore a location successfully, solve a puzzle, visit a friend, or complete a quest you earn experience points (blue stars) that advance you toward the next level. You can also get experience from trophies on your desk.

 

Talismans such as the Owl Figurine increase the experience you earn when exploring locations.

To see how many experience points you still have to earn to reach the next level, tap the blue percentage bar next to your avatar. The first number on this bar is your current experience points, and the second number is the total amount experience you need to level up.
