This application lets you play Connect4 (German: VierGewinnt) with your friends. You can either play a classic game with 6 by 7 field or customize the field to other sizes. Since this is a digital version of a game it allows for special modifications like adding bomb chips which you can enable optionally and they enable new tactics.

Windows:

• Client

The application is implemented in Java and also distributed through runnable .jar files. You need a Java Runtime Environment (8 or higher) to run the following programs:

• Client
• Server

The game is implemented as a Server-Client application. Thus there need to be one server where the clients can connect to.

1. Run VierGewinntServer
2. Press the button to start it (default port 1000 is used)
3. Configure port forwarding (if you have players outside your local network):
   • Open the config page of your router
   • Setup portforwarding to the computer where the server runs (find out its local IP) with port 1000 (default)
   • Important:
     • Players outside the servers local network must use the routers public IP
     • Players inside the servers local network just use its local IP (usually something like 192.168...)

1. Start VierGewinntClient
2. Click "Lobby" > "Verbinden"(Connect)
3. Enter a nick, the IP of the server and the port (1000)
4. Click "Verbinden"

1. In the Lobby click "Spielen" and configure your game
2. Click "Anfrage Senden" and wait for a reply of your teammate
3. You are read to go!
4. Controls:
   • Left/Right arrow -> Move chip left/right
   • Down arrow -> Insert
   • Up arrow -> Change between normal chip and bomb (if enabled)
   • Explosion: Double click on your bomb in the field when its your turn

Hint: The game chat is equal to the whipser chat
