Easy, You just type in the code "Stealth" or "Metal Fusion" and then create a beyblade. After that you battle people until you get the amount of stars you want. There are other codes I do not know that increase the amount of stars in battle.
we should have lots of stars one way is by turning to a new level or have lots of codes
