Solitaire game available for my children, but parents also love

Offered by Santa to my daughters 6 and 9 years, it is the friend of my cousin (20 years) who spent his afternoon. He even said it was a good tool to take to the lecture hall with him ... My girls love their small size to take him in the car. They quickly understood the rules and love this puzzle game purchased at the same time as another "Puzzler" which also made many envious because everyone, big and small, want to try. Bring with you on vacation, as well as "puzzler".
