Make sure that the button to start Activity (begin a game) is not a styled anchor element but a button.
The issue is that currently user could open that in a new window and that would fail, because the current approach uses the POST action to either determine the URL of the existing game or starts a new one.
This could lead to a situation when user gets an error screen with no apparent reason.
