They needed help getting started but soon learned how to play the game and they absolutely love it. It challenges their minds. Money well spent. 4 of 4 customers found the following review helpful: Great Fun, 2007-09-24 I play this with my 6 year old twins who love it. We have just completed all 101 of the training ones. I got this as opposed to 1.0 because of the training set and am glad I did. The others are a lot trickier but they enjoy the challenge and applying their ideas. I think there is a junior addition to this which I will have to get. Good fun challenging game for all the family 1 of 2 customers found the following review helpful: Great thought provoking fun, 2007-09-21 This game is not only fun to play but is a great way to learn science and physics principles. Figuring out how things work and then applying that knowledge to solve fun and interesting problems has kept me and my children playing this game for hours. We all love it! 1 of 2 customers found the following review helpful: great brain game, 2007-08-28 I love adventure and puzzle games, this one is one of my favorite puzzle games!
