My husband and myself love this game. I am not a good speller and I can play this game and win. It can be a pain at times because of some of the rules but we bend them from time to time!  You can build any where from 2 letter words to 10 depending on the stage of the game you are on. Some times the smaller words will bring the most points! We have 2 sets now! I keep one at work to play at lunch. Yes you can play solitaire! But I play like it's 4 people playing and I don't cheat to win a hand. Love it love it love it!
