Change the Game Appearance

If you want to change the font size, the color theme or the card design, you can follow the steps below:

Press this button on the app bar of the game view to show the list of secondary commands. On a PC, you can use the menu of the title bar alternatively. This menu is more detailed than that of the app bar, so you can reach almost all the panes directly.
Select the command: Change settings.
The game settings pane comes into view.
Click this button to go to next pane. Alternatively, you may press the key combination Alt+Right arrow.
The global settings pane comes into view. The options on this pane are applied to all games. In addition, the global settings are synchronized across all devices you are logging in with the same account.
Click this button to go to next pane. Alternatively, you may press the key combination Alt+Right arrow.
The local setting pane comes into view. The options on this pane are valid for the current device only. Here you can vary the font size. Changing the font size has an immediate effect on the display.
Click this button to go to next pane. Alternatively, you may press the key combination Alt+Right arrow.
The game appearance pane comes into view. Move to the theme, card face, or card back you want and select it. The change is applied immediately to the game view. The game appearance belongs to the local settings and therefore has to be set individually on each device.
If the selected card back contains a photo frame and you want to replace the photo, you must click the photo and perform the exchange as described here.
