HOW TO USE THE SHANGHAI: DYNASTY "SHANGHAI CHEAT."
> 
> 1. Create a file in the game's directory named "cheater" (The file's
> contents do not matter)
> 2. Go into the product and start a new game of Shanghai or Tournament
> or whatever (do NOT try this in a game of Pandamonium or Dynasty, as
> this will cause bugs to occur).  
3. Press control-Y
>  in a game of Pandamonium or Dynasty, as this will cause bugs to
> occur).  
4. Press the spacebar to remove a pair.  Do not use the mouse to point
and click on tiles, as this will cause bugs to occur. 

> The way the cheat works is that the game creates a guaranteed winnable
> arrangement.  Pressing spacebar follows the one known guaranteed path
> to winning.  Removing any other tiles manually will throw everything
> off and may result in an odd number of tiles at the end.
