I can hardly say enough good things about this fun and thought-provoking game (which a good friend gave to my son for his birthday a few days ago). Each of the 50 playing cards presents a puzzle scenario which you set up on the gameboard with the train pieces. The object is to move the pieces around until you can get the red locomotive off the board. The puzzle scenarios gradually increase in difficulty, but all of them are fun and challenging (even for parents!). Our family has already enjoyed many hours with this puzzle and, given the large number of puzzle scenarios, the variety of challenge levels and the keen interest to a broad range of ages, I'm sure we'll be enjoying and learning from it for a long time to come. Our children as young as six were able to play the game.

Although there are a number of pieces, they are big enough to not get lost too easily or be terribly dangerous for little ones (although I wouldn't trust those in the choking-range with the pieces). We punched holes in the card deck and keep them together with a binder ring. My only complaint is that the colors of the playing pieces didn't match the colors on the playing cards very well.
