Abstract
Abstract A flipper game having a plane-sloped playing plate arranged in a housing on which obstacles for the run of the ball are arranged. The ball enters at the head end of the playing plate and runs in the direction of the slope down to a target opening arranged at the foot end of the playing plate. The slope of the playing plate can be regulated thereby altering the running velocity of the ball for production of varying degrees of difficulty. The slope of the playing plate can be manually set or incremented automatically depending on the score.
