You need to play the Daily challenge to move up a level. So I suggest you should take care of your monster like feeding it, taking it out for a walk and play games in the puzzle palace so you can work your way up to level 20.
You unlock level 16 the same way you unlock all the other levels, by earning XP. It just takes more XP to level up the higher your level is.
To earn XP:
Play with your monster.
Keep your monster feeling well.
Feed your monster.
Earn points playing the Daily Challenge Puzzle.
Earn points playing the puzzles.
Earn points by decorating your room.
Complete Quests to earn experience points (XP).
Remember, you can only earn a certain number of points each day.
You can see how far you are away from the next level by looking at the progress bar below your level number. Just remember, you can't level up unless your monster is feeling well enough!
