This project is based on Arduino Platform. The game we choosed here is very common in casino, club and the indoor playing. This project uses three different coloured LEDs (RGB led) that show three different cases, these three cases are continuously changes with random blinking of different coloured LEDs, player will have jackpot when he/she will get all the three LEDs with same coloured cases. It is assumed that the reader has gone through the project how to get started with the arduino and interface LCD with arduino.
Here are some images of complete set up of Arduino based Jackpot Game.

Working
This is a simple and interesting LED game for children’s. The circuit of this game consist a 16×2 liquid Crystal Display for displaying the status for LED’s like JACKPOT, SORRY etc.
When player pushes the switch, LCD will display wait till the result gets displayed. LEDs goes on blinking randomly and after certain time it will get stop with randomly cases on those three LEDs, if player gets exactly same cases on all the three LEDs LCD will show JACKPOT otherwise it will show “try it next time”.

Connections of this circuit are very simple a 16×2 LCD is connected to Arduino in 4-bit mode. And data pin is directly connected to arduino analogue/digital pins (A0/14, A1/15, A2/16, A3/17). And control pins are connected to pin 11 and 12 of Arduino. A push button is directly connected to +5 volt for play game. And three RGB LEDs are connected to pins (2,3,4,5,6,7,8,9,10) of Arduino.
Programming of this project is also very simple. Here we used random number generator. C language already contains a function of generating random number.

Rand();
And calculation as follow.
temp=rand();
temp=(temp%100)/3.50;
it will generate a random number less then 28.
It generates a integer random number and then further some calculation we gets a random number for use. In program a 2 dimensional array defined for show pattern on LEDs.
