					Four By Four

Description:

	 A three dimensional game of tic-tac-toe on a 4x4x4 cube.

Object:

	 Be the first to score four in a row.

Instructions:

	 1.  It's you versus the computer.

	 2.  There are five skill levels. Press the "Skill Level" button to select your level
	      of play. The program defaults to the hardest level. Changing the skill level in
	      the middle of a game will force the start of a new game.

	 3.  The screen on the left is a 3D window. A mouse drag in this window will rotate the 
	      view to any desired position.

	 4.  The screen on the right is a 2D window which displays all 18 faces that exist in the 
	      4x4x4 array.

	 5.  Click on any of the small gray spheres (in either the 2D or 3D window) to select a position. 

	 6.  Positions owned by you will be marked in red. Positions owned by the computer will be 
	      marked in blue.

	 7.  Click the "Undo Move" button to take back a move.

	 8.  Clicking on any of words "Face X" in the 2D window will cause that particular face to highlight
	      in the 3D window. Clicking the word again will un-highlight the face.

	 9.  The final score is based on skill level, number of moves, and time. Select the button
	      "High Scores" to see a list of the top 20 scores. There is no penalty for using the
	      undo button.

	10. Good luck.

General Strategy:

	 1.  There are a 64 positions from which to choose. In total, there are 72 possible winning 
	      combinations. 

	 2.  The outer four corners and the inner "core" of eight have the most winning combinations,
	      7 each, and should perhaps be chosen first.

	 3.  Use the 2D window to keep an eye on all the faces.

	 4.  The computer plays well at the highest skill level (the default). There are, however,
	      faults in it's logic that can be exploited. Thus the human player can win even at the
	      highest skill level. In the beginning, however, you may want to start at the lower skill
	      levels and work your way up.
