I have purchased numerous ThinkFun games. Our favorites include all versions of Rush Hour, Sudoku, Clever Castle, Zingo, S'Match, and Chocolate Fix. I've tried a few others which we like, but those are my favorite. This is a new one to add to the favorite list! Having spent the summer learning how to play Chess, I am very excited that we can use the rules of the chess pieces to solve logic puzzles. It is really, really well done! The goal of each card is to have the chess pieces capture the other pieces until only one is left standing. The game is set up in a grid, so that you can look up the answers in the order at which you need to move the pieces. Ex. A2 moves to B4, etc. etc. The chess pieces are in a sliding drawer underneath the case which holds the challenge cards. Just beware, the cards are difficult to get out at first. It took some effort to slide them out.
