Of course, access to private games is restricted. For instance, in a public room, only the creator of the demo board can access it. In order to grant other players access it is necessary to use the Access List. In the top right of the board you will see a button named options. Press the options button, in the resulting dialog which appears, select Access List. You will now have a pop up appear, composed of 2 parts. On the top is a list of the names of those with the right to access. On the bottom is a text box. Type the names of those players you wish to grant access into the text box, then press the enter key to register their right to access.
