These 3 puzzles are fun to play with.Bright colors,hard plastic and smooth surface .Just like the average cube the goal is mess them up and then return them to have each side all one color.Not the average square cubes though.The different shapes give it a new twist! Easy to rotate and smooth motion when rotateing. Keeps you occupied for a long time. #RankboosterReview #Sponsored #Playwin https://www.amazon.com/dp/B010N111KS/ref=cm_cr_ryp_prd_ttl_sol_4
