Beats me.

You must sacrifice games to the masses of steamgifts, It is rumored that if you sacrifice enough you will ride above the karmic circle of gifting and achieve enlightenment.

Engage your pokemon in a lot of battles. It helps to have an EXP share

By doing giveaways. You can see more on the FAQ and you also learned a good leason here, most people here are trolls when you don't read the FAQ =p

As other's have mentioned, you will find all the information regarding levels in this post from CG. With that, welcome to the site! We would encourage you to read the FAQ and Guidelines as they answer many questions new users sometimes have here.

Slay worms for the first few levels, then go for werewolfs and single horned 2 legged kiwi things. Then go for trolls to achieve the max level.

If you yell for a long period of time, starting quietly and getting louder as time goes on, you can easily increase your power level over 9000.
