The word building game is a well known game all over the world. It is also called as scrabble. In this network-supported game, four players can play the game together sharing the same matrix board. Players can join their corresponding opponents directly by searching. I have used UDP sockets for searching the hosted game and TCP sockets for game processing. This game can be played within the subnet.
