The towers made purely of metal bars take all the fun out of the game. It becomes too frustrating to knock them down and I end up quitting rather than trying to beat them to move on. This game was fun because of the destruction of the towers, not the endless trial and error to find that perfect spot to hit something.
too much luck involved. i can be ahead by 3000, and the computer will do a ton of rolls that lead to free spins and boat loads of points, while i'm stuck getting singles and double pairs of 1s and 5s. little to no skill involved.
