Since I ordered this game a year ago - without knowing anything about it - it's become the number one favorite board game of all my friends.  Most of my friends now own this game, and my monthly game group plays it almost exclusively.  I even play it over my lunch hour at work several times a week with some other Qwirkle fanatics.  One thing I like about the game is that two people can enjoy it as much as 4 or 5.  This is one of many very creative games offered by Mindware....check out their website.
