I played this as a child and teenager 20 yrs ago.  I watched all my younger four siblings play it and love it.  I now had a 4 yr old girl that LOVES it!!!  I bought it when she was three and I was sick of candy land.  She picked up on her numbers very quickly when I told her she could play if she remembered her numbers.  She understands the small amount of strategy.  I played the younger child rules where they can leave the outer two cards face up about four times.  During those times my husband and I played the older child rules.  She quickly caught in and wants to play like us.  I have been using this game for homeschool preschool math.  She understand higher and lower numbers with no problem now, and it was a very fun way to teach it.  We own hundreds of games at our house and this is one of my favorite two games for her age group.  I would recommend for any family.  While it is simple to understand for an adult, most adults are willing to play many rounds with my child.  Each round takes less than five. Minutes and the game can end after just one round.
