Our seven year old son got City of Zombies for Christmas. He already had a smaller card based version.
It's a fantastic fun cooperative game which helps children and grown ups improve their mental arithmetic.

We picked this up and playing with our seven year old and the year old joins in where she can, great game and already established as a favourite.
Great recomendation!
