Part 1 - This is a "best of" a couple sets. Some levels have lots of bricks; some have worms or snakes; and some have both. But the means to overcome these is provided; so it shouldn't be too objectionable. The challenges are pretty simple; especially if you look at what's going on and understand the "rules". After all; I won them; or they wouldn't be here! I hope you have fun!
Level sets are graded in Ricochet Infinity.
