http://roguepinball.com/index.php?action=downloads;sa=view;down=466A new VP 9 build of the 1949 Williams game De-Icer.
This is the FS mod of PBecker1946's desktop.
Even at this early stage of figuring out how to use flippers in his game design, you can see several of Williams' inventive directions already beginning to show. Most obvious is his use of asymmetry, something that became much more extreme in his games just a few years later. Another feature is the TILT reset which was a Williams invention and exclusive feature for several years. Harry Williams had invented the original TILT feature many years earlier, and how tilting interacted with game play (i.e. how much nudging was allowed) was something he remained focused on. De-Icer was one of the first games where tilting didn't end the game, but only the ball in play.
