Have a united aztec ball bowler. Everything is in good shape, but when you bowl, it gives you a strike every time. The appropriate pins go up if your shot is off, and if you play flash or one of the bonus games it does give you different point values for a strike as opposed to a miss. You can only throw one ball and then it cycles as though it was your second shot. The kids like the fact that they can throw a gutter ball and still get a strike, but it doesn't lend much to competition!! help would be appreciated. Thanks, Jeff
