I enjoy the randomness of the games because I never really know ahead of time how hard the game is going to be. I also personally play without solutions. I figure when the game is complete, it is right, so I didn't waste paper and valuable game space with the solutions. I hope you have as much fun with these games as I do.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Robert T.
