So you need so much coins or unlimited coins, (you can get unlimited coins through hacks, mods and apks) Hunger potion and Max potion. Ok so first buy hunger potion and Max potion as much as you can (Make sure they are equal in number) Second drag the hunger potion to Pou and after that drag the max potion and again drag the hunger potion to Pou and after that drag the max potion and just do it all over again. You will see that your XP will grow and you'll level up in no time! I always do this so that I will level up in a minute! Awhile ago I did this thing for hours and from Lvl. 20,I got all the way up to Lvl. 69 which is awesome.
