TUTSTOMB (for Windows 3.0 or 3.1)

  Playing instructions:

  Tutstomb is also referred to as "Pyramid" or "Thirteen".
  The object of the game is to clear the tableau by matching
  two exposed cards that equal 13 points.  Kings are worth 13,
  Queens are 12, Jacks are 11 and all other cards are worth their
  numeric value.  Aces, therefore, are worth 1 point.

  Using this synopsis, an exposed King could be eliminated all by
  itself, simply single click on it.  A Queen and Ace can be eliminated 
  (they equal 13) by dragging either of the two cards on top of the other 
  and releasing the mouse button.

  Continue in this manner until the tableau is empty or until no
  further plays are possible.

  Enjoy!
