My energy bar didn't refill entirely after leveling up

The energy bar will refill 24 energy after every level up. You can get free energy gifts from your friends and use up to 50 energy from your inventory per 24 hours. You can store up to 10 of each of the +1, +2 and +3 energy in your inventory. The price to play of each scene is displayed in the scene menu.

Energy is received as a gift from your friends, by visiting neighbors, purchasing it in the Marketplace, when leveling up, or automatically over time. 1 Energy is earned every 5 minutes, as long as you have less than the maximum energy available.

FastFind challenges currently cost 3 energy to play and scenes will require between 8 to 10 energy. The cost of each scene is displayed in the scene menu.

You can get 1 energy per neighbors visit per day and 2 energy on first-time visit. You can collect minimum 5 and up to 20 energy per day. Please note that it also depends on your reputation level so if your reputation level is 15 then you will receive up to 15 energy max when visiting your neighbors.
