I need more details from you:
What platform/programming language are you looking for? Web app or Window App or Mobile App?
Do you want me to provide you the design and content, or I will code from your design and content?
Looking forward for your clarification
How will i do it:
1- A server app will manipulate the connection between the multiplayers
2- Html,javascript and php code to design the webpage through which players will play
Note: if the game is to be played not from the browser (No need to design webpage) then it's recommended that the client app will be in Java
The game can be any simple game as you suggest
