The game is simple. As stated above, it is a scoring game and the competitor who scores 100 points rapidly (in short steps) is the winner. For scoring, one has the option of pressing either switch S2 or S3. Switch S2, when pressed, makes the counter count in the forward direction, while switch S3 helps to count downwards.
Before starting a fresh game, and for that matter even a fresh move, you must press switch S1 to reset the ci cuit. Thereafter, press any of the two switches, i.e. S2 or S3.
On pressing switch S2 or S3, the counter”s BCD outputs change very rapidly and when you release the switch, the last number remains latched at the output of IC2. The latched BCD number is input to BCD to 7-segment decoder/driver IC3 which drives a common anode display DIS1. However, you can read this number only when you press switch S4.
The sequence of operations for playing the game between, say two players “X” and “Y”, is summarised below:
Several players can participate in this game, with each getting a chance to score during his own turn.
Construct the circuit using a multipurpose PCB. Fix the display (LEDs and 7-segment display) on top of the cabinet along with the three switches. The supply voltage for the? circuit is 5V. You may use three batteries with series connection to operate this game scoring display circuit.
