ABSTRACT:
A child's toy for playing checker at a check out stand used in retail stores and the like. An on/off switch is connected to a battery power source inside a housing. The power source, via electrical leads, is connected to a red and green light mounted in the top portion of the housing. An item switch, which is temporarily engaged by different play items to be checked, is also mounted in the top portion of the housing and electrically connected to the power source and the red and green lights. When the on/off switch is turned "on", the red light is turned "on". When a child places a play item to be checked against the item switch in the top portion of the housing, the item switch opens electrical lead to the red light turning it "off" and at the same time closes the electrical lead to the green light turning it "on". The toy can also include a buzzer which sounds when the green light is turned "on". When the play item being checked is removed from engagement with the item switch, the green light is again turned "off" and the red light is turned "on". In this manner the child can pretend to play checker at a retail outlet.
