+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.
