DS(4) loves UNO and to start with we would lay all our cards down (to be fair) which was great for helping teach strategy but now he lines them up in a gap in our wooden floor boards which stands them up smile
He also loves other games like snap, dominoes, snakes and ladders, guess who and jenga. I think it is great for learning fair play, being a gracious non-winner... Mind you in UNO he often wins, no need to help him smile
