These neat puzzles fill your time and mind with wonder as you move them around with ease and then think "How did i do that?" or " How do i fix it?" I like how they are not the basic cube form. The colors and shapes are bright and fun to play with. #rankBoosterReview #Sponsoned #Playwin https://www.amazon.com/Playwin-Aliens-Pyramid-puzzles-Collection/dp/B013UA91QK
