Slightly limited, but a favorite with 6 and 9 year old boys. We started with all cards face up and playing for the same goal as in the directions. Eventually, have made the game more and more difficult as we continue to play...the game directions way to play are pretty simplistic. There are ways to adapt this to make it even more challenging so I look forward to the family growing into this and using with math for high numeric values (which is not in the directions, but possible). Funny cards...good stuff here.
