Rat-a-Tat Cat

Annika loves this game - probably because she can beat me every time. Somehow it takes a level of concentration that my 9-year-old has mastered, but I have not. You have to pay attention to your cards, and trade out to get the lowest score... but you don't get to see what your cards are! You can only see what you have when you swap a card from the draw pile - but then you have to remember what it was, and where you put it.

The age recommendation is from 6 years, but you do have to be able to add and keep track of your score by yourself. Having four numbers in your head and keeping track of their sum... I would say 8 years would be better.
