Looking for something to keep your child's brain churning during summer? Look no further! I purchased this for my kids a few years ago. It is a "toy" that causes the user to begin to think using the same logical approaches that coding uses. It has puzzles to solve from very easy at the beginning to advanced by the end. The unit itself is built to last. It is recommended for ages 8+. It sells for $70. Our set is in pristine condition. All the parts are there and there is no damage. The book is free of markings ready to be used by another future programmer.
