Abstract: A simulated football game having a magnetic disc rollable out of a chute onto a scrimmage field on which defense players having a piece of iron embedded therein are movably situated, a huddle being releasably retained to retain the disc in the chute. The disc is used for determining running play yardage, the disc being rollable into a defense player. A calculator wheel is rotated in only one direction by dual gears regardless of the direction of rotation of the gears and simultaneously moves a marker over a marker field to indicate the position of a football relative to the marker field. The wheel is used to ascertain yardage resulting from passing, and other type plays. A marble carrier is rotated a fraction of a complete revolution each time a plunger is depressed for indicating a play and releasing the huddle to allow a disc to roll out of the chute. The carrier in being rotated, at times, discharges a marble to roll onto the scrimmage field for indicating whether there is a penalty or a fumble.
