relays for game button circuit

hello guys...im totally a newbie here.. so this is what i went here for. my sister asked me to create a game buzzer device.. i mean. two buttons,1 light each button. when you hit your button.. your light will switch, and the when you push the other button it wont work. simply game buzzer button circuit.now without any knowledge ive been looking for a do it your self circuit..or is there any relay that i could use for that?like a first come for serve relay? thanks for your reply and suggestions guys... PS: i really want it very simple to the point that youll just put them together and thats it. :)Be Like a Tire Which must go on even the road is rough

Google (two button) quiz circuits. I suggest viewing Images. Maybe the simplest is from electronicdesignworks.com reflex action game; namely: Usually they use SCRs as per the Quiz Timer circuit at zaleski.org's from 101-200 Transistor circuits.pdf - ie:

ok im confused about the last sentence he said.. "Similarly when S1 is pressed first, the lamp(L2) associated with S1 will glow preventing L1 to glow. Since, at a time only one lamp will glow, this circuit will always give correct judgment." i thought it was when you pressed S1 the L1 will glow and it prevents the L2 to glow even if S2 is pressed?Be Like a Tire Which must go on even the road is rough

S1 turns on T1 which illuminates L1. T1 turning on raises p to a higher voltage (maybe 5V) hence if S2 is pressed, p is too far above 0V (GND) to turn on T2. T1 & T2 are PNP transistors which need their Base thru S1 & R2 or S2 & R1 to a reasonably more negative voltage than their Emitter (to +6V via S3) to turn on. Maybe I'm wrong else he's confused the circuit sides, but either way, it should be easy to check during testing or swap leads after assembling.

Thanks for the reply sir! thanks you so much. now ill try to build one of these circuit for more/most enjoyable christmas party :)Be Like a Tire Which must go on even the road is rough
