We bought this game in France this summer on a rainy afternoon, after playing it once in the toy shop. It is VERY addictive, and no two games are the same. Our seven year old and twelve year old can play it, but it is equally challenging for the grown-ups too! Two or four players can play, and the game enters a new dimention playing with four. I am just about to order one for my father-in-law's birthday present (who is in his sixties), and will order one for my brother in Australia next month for his birthday - although this is not just a game for the men! An added attraction is each game doesn't last too long - between 10 and 20 minutes, so family members can take it in turns, or it can be played when there are a few minutes to spare!
