The first 4 rounds are from a set I was going to create but packed in which was going to be for kids. The last 11 rounds are a chance for a no ship bonus. An indicator will show you which side of the screen you need to be to get the bonus. After the last brick is destroyed at the end of each level you have 1 second to remember which side you can get the no ship bonus. Is it worth losing the ball for? You decide. Oh and before I forget some of the rings are a bit hard to get.
Level sets are graded in Ricochet Infinity.
