My grandson started playing this when he was 4 years old! He was captivated by it and quickly learned all state capitals and positions and shapes! His older sister was a bit jealous.. he loved the stacking challenge too( as does grandma!). He moved on to stack the countries. He knows way more than I do about where everything is. I asked him one time "what country is between Russia and China?" He immediately answered "Mongolia"--- and I was amazed! He thought everyone knew that
