Debug Mode#
Like many other games include with Windows Vista/7 have an internal g_debugEnabled variable. When this variable is set to a non-zero value, it replaces the normal menu with this debug one. The options are pretty self-explanatory. They allow you to see the opponents' hands, test the AI, and choose whether to win or lose.
Setting that variable also enables the very same block & pause modes and logging as described on the Solitaire page.
