I added 2 new Games: first i added Minesweeper. it includes 3 difficulties, win-detection, placing flags, not being able to accidently click on flagged fields, reset button and introduction into the whole jFrame; secondly i added connect4 for singleplayer and multiplayer. i used a lod of rendering code and an altered verion of the server form the chess game, so they look similar. i will try to make everything look similar, so that it is easier to understand for the user.
