Our family loves to play this stacking game and when I saw the oversized ones, I thought it would be super fun. It is, but with a caveat. Mainly it is that wood is not very smooth, and you really have to push on them to get them to move, so they don’t all come tumbling down! Even our youngest engineer figured out this wasn’t going to be an easy win. The product is made for 8 years up and our kids are 6 and 7. That may factor into it. We will try it outside with more friends and family  and that may loosen them up. The quality is good and the carrying bag is excellent.
