My new Houdini has over 120 plays on it, and if you really look hard thru the invisiglass you can find about a dozen barely visible shallow dimples.
And thats the way it is with balls flying fast and bouncing all over, it is not a slow game. Nobody can convince me that playfield dimples in number are a normal thing after owing this game a few weeks. Higher quality playfields than Stern's CAN be made and its doubtful American Pinball will release their manufacturing secrets, and it is doubtful that Stern will spend the extra money to make their playfields with matching quality.
