If you want to share the current game state with anyone, you can do the following:

•  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: Manage game files.
   
• The game files pane comes into view. It shows the name, the comment, and the saved status of the current game:
  • × - the game is not saved at all yet. If you click on the icon, saving is performed.
  • ● - a previous state of the game is saved. If you click on the icon, saving is performed.
  • √ - The current state of the game is saved.
•  Press this button to perform sharing with the send email pane. If the button is not visible, you can press this button  to show the list of secondary commands and select the appropriate command from there. If you have selected only a single file, it will be shared as it is. If you have selected multiple files, they will be first packed into a ZIP archive, before the ZIP file is then shared. In any case, the file to be shared is still placed in the folder of the Log files before the send email pane is displayed to send it.
  If the current game was not saved yet, this was done automatically before.
