We have been pleased to try out a new kind of puzzle this month. This self contained puzzle was created by Enlivenze LLC. We received one FlipStir Puzzle--Statue of Liberty. There are currently 5 puzzle choices with 2 levels of difficulty. Level 1 puzzles have pieces with straight edges and level 2 puzzles have wavy edge pieces. Level 1 puzzles include Rainbow Pencils and T-Rex. Level 2 puzzles include Statue of Liberty, Solar System, and Periodic Table of Elements.
