Huge Rubik Cubes
YongJun MoYu 13 Layer, made in China, 2015.
(plastic, 5+1/4", over 1000 pieces, weighs 5+1/3 pounds)
This cube goes improves the 11x11x11 design with extra tabs on the ends of some pieces.
Tony Fisher
does an impressive job in a video
showing a complete
disassembly
of the cube,
and a second video showing a
reassembly;
he identifies
38 piece classes.
Even larger Rubik's cubes have been custom made with 3D printing.
In February 2011
Oskar Van Deventer
presented
a Rubik 17x17x17 cube called
"Over The Top"
(using
Shapeways
3D printing technology),
In 2016
Coren Puzzle
made a
22x22x22 cube),
with 2,691 pieces,
and in 2017
Grégoire Pfennig
demonstrated this 33x33x33 cube with 6,153 pieces (and 6,534 stickers):
The reduction to a
Rubik 3x3x3
solution used for
Rubik 4x4x4
and
Rubik 5x5x5
solutions can be used
(in principle, with enough patience)
for solving large cubes of any size.
