#goldenwide Mirror Cube (Toy) So much to make me feel so ignorant. Haha haha. The older I get, the more important it is to keep my brain active and busy. You know what they say. Use it or lose it. Unfortunately, I think I've not been using my brain as much as I should.. These puzzles help me keep my brain functioning through activity. Each puzzle offers critical thinking and fine motor skills. There are six different puzzles that provide hours of fun. The smallest is a two by two square with four different colors. You would think that with so few squares in the puzzle to get mixed up would limit the number of combinations possible, making it easy to solve. You would think..................... but no. Each puzzle offers different levels of difficulty but none are simple. Not for me anyway. The movement is smooth with each of these puzzles. The plastic is tough and holds up to repeated droppings. Yes I said repeated. Some "drops" we're even intentional, Hahahahaha. I was given for free in exchange for an honest unbiased review. I consider quality of materials, workmanship, safety, and ease of use when evaluating each product. I appreciate all questions or comments. Thank you for reading my opinion.
