I found this game very frustrating and not much fun; that is until I found the two player turn-based variant on the Geek. It completely changes the game to a very tense, fast, race game where one is trying to get all of their colored chits first.
With the original rules I give it a 5, with this variant it is hovers between a 9 and a 10.
Check it out, especially if the game has lost its appeal for you. Its a totally different and, IMHO, much better game.
