Free Cell

Finally found a game with a genuine challenge and on a level playing field. I enjoy the challenge of the hard level but Im not sure one should be able to do an "undo" more than once. I sometimes make a mistake because I have difficulty with color recognition and I like to be able to "Undo" once, but that should be enough. I love the game. Thanks.
