FreeCell (Microsoft, PC)

FreeCell is another all-time favorite among lazy workers. It managed to spawn quite a lot of clones seeking to improve upon the original.

Windows XP and earlier


Unlike its sister game Solitaire, the debug menu is still accessible here. Press Ctrl + Shift + F10 to trigger a dialog box offering three options: Ignore, Retry, and Abort. Ignore just closes the message box, Retry causes you to lose when you make your next move, and Abort induces an instant win.

The menu was likely there to check whether the win/lose stuff works properly, as there doesn't seem a point in cheating in a game like this.

Windows Vista/7


On the other hand, like Solitaire, FreeCell was rewritten for the release of Vista. Versions since then have an internal g_debugEnabled variable that when set to a non-zero value replaces the normal menu with this one. "Toggle Hint Rankings" and "Tweak" have no code behind them, while "Toggle Cheat Keys" enables the ; key which lets the game play the next move.

Setting the g_debugEnabled variable also enables the cheat keys allowing any move, block and pause modes, and logging as described on the Solitaire page.
