This project is based on game connect. It is single player game. The code is very simple. Please follow the instruction to run this game properly..

it hase two files : COMM.h and Game.cpp

COMM.h should be place in include directory to make this code work. After copying just compile this and enjoy the game…

The keypads are as follows:
-the LEFT AND RIGHT arrows to move on the board;
-and the ENTER key to launch a CHIP;
