I day I received the game from ThinkFun I sat down to play it. My original intention was just to see how it worked as it has a very interesting look to it. However, I ended up playing for over an hour and worked through the first 10 challenges. I hadn't realized I had been sitting for so long because I was having so much fun moving the little cars around to allow the red car to move forward and out of the gridlock it found itself in. I had things I had to do, so I put it away, but no more than an hour passed before I had the game out again and worked through several more challenges. I found the game to be extremely fun, challenging, and addictive. I think that anyone of any age who loves puzzles or other similar games will love Rush Hour.
