About


You are now looking at the home screen on Backgammon Studio. The default version is a lighter version where most of the content is hidden away in the menu system (top left corner).
You can configure this home screen in many wonderful ways by the cogwheel icon in the bottom left corner. You can also switch to different homescreens and menu systems and also change many other parts of Backgammon Studio in the settings that you can access in the top right corner.
Good luck! Best regards, Terje Pedersen
