I bought this game because I thought my son, 5 years old, would really enjoy it. He loves playing with the game and has even been able to do some of the 3-D pyramids by himself. It is a great game for teaching spatial relationships. My daughter (7 years old) whose spatial skills are not as good has a harder time doing the pyramids, but enjoys the game as well. The adults in the family like it too. It has been brought out at parties and is a good challenge for everyone!
