The name of the players are displayed as buttons on a scrollable panel. Player panel is on the right side of the Button Panel. Above the button panel, we have Dice Panel.
Improve Property button is used to upgrade a property. Draw Card button is below the Buy Property button, it is used to draw an action card, such as a Community Chest Card or a Chance Card. The button becomes unpressable if the square that the player on is not a property square or if the property square is already owned. Buy Property button is used to buy an unowned property. Roll Button is used to roll dice and move the player. In the middle part, we have the Button Panel. The board is displayed on the left side of the screen. The game starts after the Start Game button is clicked.
Regardless of whether you create a new game or join to an already established game, in the server screen two options are displayed: Start Game and Quit Server.
So, if the game is played between different computers, their IP addresses should be known. If you click on the Join Server button instead, the address that you want to join into will be asked. You can either start a new server by clicking the Start Server button or join to an already existing server by clicking the Join Button.
