Start with five balls that only count as used when shot. you also have infinite balls when playing bonus levels. either the powerball and extraball bonus are possible only if you direct hit them. you can hold up to 10 balls which five are only extraballs. it means that each level you beat you can have another shot up to five possible. so, in order to get all the 10 balls you must hit the extraball cans and turn them into bubbles. when running out of lucky, there are quite few stuff you can do like combos and prizes from hitting the bell. use up all your balls and the ring bell will tell you when the game is over.
