Magic Cube 7D is a fully functional implementation of seven-dimensional analogue of the Rubic's Cube and some other puzzles.
Now there are twelve of them: hypercubes ranged from 3^{4} to 5^{7}.

What you see in the picture is a solved 3^{7} cube.
The display shows 7 of its 14 sides at a time plus parts of six more (seven-dimensional cube has 14 sides!)
One side is always completely invisible. If you scramble the puzzle, picture will be more interesting:

If you think that it's difficult to find something in this picture, you are right. But the program can help you to hide some pieces of the cube and make some others transparent:

Look more understandable? I also think so. Indeed, 3^{7} has only 2172 moving pieces with 10206 visible stickers (and 15309 of them may be on the screen at the same time).
This puzzle has about 3.37 x 10^{8935} possible states, one of which is the solved cube. There are only few people who could solve it. But if the above puzzle is not enough for you, you may try something bigger:

It's a 5^{7} cube. 78110 moving parts, 218750 visible stickers... May be somebody will solve it, say, in ten years or less.

Are you ready for the adventure? Download the program here. Unpack it in one folder and double-click the .exe file. It requires Microsoft .NET 2.0. Now program works in Windows only (and there are no plans to convert it for Linux). See the instructions here.

Magic Cube 7D took many ideas from MagicCube4D project. I would like to thank its developers Don Hatch, Melinda Green, Jay Berkenbilt and Roice Nelson for this wonderfull puzzle and for the very interesting 4D Cubing Group!

Some links:

- MagicCube4D - Not only cubes. There are many other 4D puzzles inside one program, most of them are still unsolved
- MagicCube5D - 5-dimensional cube. If you want to work in 5D without fractal unfolding of extra dimensions, this is the way to go.
- Magic120Cell - 120-Cell is one of two largest regular polytopes in 4D. This puzzle is a 4D analogue of the 3D Megaminx.
- MagicCube4D Hall of Fame - Most of hypercubists started with 3
^{4}cube. Now there are more than one hundred of them. - Extended Hall of Fame - When you are solve something more interesting than cubes, go there. This page has enough empty lines.
- MagicCube5D Hall of Insanity - They solved MagicCube5D puzzle. They are heroes.

Good luck!
