Unfair rigging of machines

Although I enjoy frequently this place, they are very unfair with their scoring system. Just because we could beat the scores on 3 different occassions, they tampered with the scoring system and increased the points needed. Needless to say, this puts a damper on our spirits because we are out to have fun, not be weighed down with people who can't believe that some of the games are beatable. It's very unfair and takes the "Fun" out of the Fun Company!!!
