The Teraminx (7x7x7), is one of the Megaminx's higher-order variations. Similarly to the Megaminx, it is a face-turning dodecahedron-shaped twisty puzzle. The difference is the amount of "layers" each face has (3 instead of 1 in the Megaminx) resulting in no less than 372 center pieces, 20 corner pieces, and 150 edge pieces which together create an enormous amount of possible combinations. It was invented by Andrew Cormier in 2008 and was firstly mass produced by cube4you in 2009. This version of the puzzle weighed almost 0.5 kilogram (1 lbs).

Solving the Teraminx is quite similar to solving the Rubik's Cube 7x7x7. True, it takes much longer and a lot more work than a Rubik's Cube 7x7x7 however the general method is the same. The Teraminx however, does NOT have the edge parity case. One recomended method for solving it is the famous "reduction" method. First solve the pentagon center of each of the faces, then group the edges together and finally solve like a regular Megaminx. 

The Teraminx is not an official WCA puzzle however the unofficial record for fastest solve belongs to Frenchman, Matthieu Aubert and is 23:04.94 minutes.

shuffle: instant regret

Crazy cuber

That just looks so stressful to solve

Babb

Hats off to all the people who can solve this

Bruh this looks impoppable

RYAN

I DID I IT ONLY TOOK 84259827396879487 DECADES

i broke the record in 12:15 seconds, though it was hard you just need to learn a lot of algorithms.

ican never solve this

when you look at each corner it looks like a normal 3x3

bro

i just scrambled it but then I SOLVED THE ORANGE SIDE

uwu

i did it so i can flex on my friends who dont realise that cubes dont get harder as they get bigger

...

I solve it in 4 second Just with refreshing the page

Label16

i made a pattern with this dodecahedeon

Coolguy

Yay! I solved it in 6246395427276257934288225837353387358336387336892851469.8364272927252882714158 years!

da best kuber

bruh i solved it in four seconds

El Goblino

I did it in 4 hours. Yay :D

JPERM2.0

bro i can solve a petaminx this is EZ. (although petamix takes me about a year)

Youssef

do it more bigger it is so easy

aaxolotl

i solved it with solve button 😂

Haha

I can’t even get one side

aaxolotl
