Cut the Rope Om Nom's Playground DELUXE SET instructions
This is the most maddening set of the Playground sets so far. As the largest set you are given lots of pieces, but getting them in the right places, not so easy. The illustration on the back is not much help, as you have to go a level higher, to get it to sort-of work. Once constructed, it only half works anyways, as things need to fall, land, and spring perfectly for a win. Still though, I had fun as it challenged me so much. Look for it at Toys R Us and give it a try if you dare!
