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. diff --git a/src/FourByFour/scores.txt b/src/FourByFour/scores.txt new file mode 100644 index 0000000..0ebc31a --- /dev/null +++ b/src/FourByFour/scores.txt @@ -0,0 +1,20 @@ +1 Bart Simpson 5283 +2 Dwight Eisenhower 5105 +3 Ken 5061 +4 Barbie 2883 +5 DoubleMint Twins 2195 +6 Robin Hood 1772 +7 Jack Benny 1604 +8 Anonymous 1550 +9 Duke 1501 +10 Jack Paar 1499 +11 Barney 1488 +12 Mick Jagger 1472 +13 Howard Hughes 1329 +14 Bugs Bunny 1328 +15 Suzi Chapstick 1302 +16 Forest Gump 1244 +17 Alfred Hitchcock 1231 +18 Roman Polaski 1168 +19 Missy Giovi 1106 +20 Bill Joy 1002 |
