Magic120Cell

 

Here you'll find a fully functional 120 Cell permutation puzzle, which can be considered the 4-dimensional analogue of Megaminx.

 

This is one example view of it scrambled
(some layers have been cut away).

 

This puzzle has an obscene number of parts (2641 pieces with a total of 7560 stickers).  It also has a comically huge number of possible positions (2.3 x 108126).  David Smith calculated this for us and has provided all the digits of this number and a high quality explanation of how he derived it.

Rest assured that Magic120Cell is solvable!  After the first release on May 4th, 2008, it was a little over 7 months before the first successful solution, but by December 13th Noel Chalmers had done just that!  He currently is the only person with this claim to fame - here is the log file of his solution.

Solve any of the available puzzles and I will also include your name and log file on the site as well (just like is done for the cube puzzles in the The MagicCube4D Hall of Fame and The MagicCube5D Hall of Insanity).  And no worries because there are features to help you along your way.  Below are some screenshots showing:

- how you can turn sets of cells off to focus on portions of the puzzle (in this case only 3 of 12 cell rings are left displayed).

- how you can highlight only certain piece types.  Like the 4-dimensional Rubik analogue, there are pieces with 0, 1, 2, or 3 different colored stickers attached.

(These pics show one of the simpler puzzles with repeated colors on cells in the solved state.)

2C pieces highlighted

 

2C + 3C pieces highlighted

Only 2C pieces not highlighted

If you're going to try to solve the full puzzle (highest difficulty with 120 different cell colors), and I hope you do, here is an indispensable hint to help you distinguish between the large number of colors.  Shift+Ctrl+Click provides piece finding functionality.  Full info is on the help menu in the program.

 

There is more to see and discover, so install and take a look around.  I hope you enjoy!

These were written for the non-puzzle version of this program, but some info there may help you until I am able to write out notes for this.
