**Welcome to The Rubik Zone**, a site for all things related to the famous Cube of Erno Rube.

I got my first rubik’s cube as a gift from my uncle. It looked cute and innocent – a bunch of brightly colored squares. A few twists later, and it was messed beyong repair, and stayed that way for months.

Now, more than 20 years on, **The Rubik Zone** is here. Check out the menus to see what we have.

On the original packaging of the first Rubik’s cubes sold, the distributor boasted

*More than 3 billion combinations!*

This has been compared with McDonalds boasting

*Over a hundred and twenty hamburgers sold!*

In actual fact, there are over ** 43 billion billion** combinations. This is a number just a bit too big for most people to grasp. But it’s actually not as big as you might think.

For example, it’s the cost of only 70,000 Iraq Wars, measured in Iraqi Dinars. Now 70000 is a number I can wrap my head around.

Alternatively, imagine

- you start buying Rubik’s cubes, messing them up, and posting them off to other people.
- Suppose you kept doing this until you had posted a cube to every single man woman and child on earth.
- Suppose also you persuaded
*everybody else*to start doing the same.

*just over*43 billion billion cubes lying around. And guess what? There’d be about a 2 in 5 chance that

*one*of those cubes was actually solved, by pure chance.

*Alpha Centauri*.

**a new, Rubik moon!**It would have its own gravity – not strong, admittedly, but strong enough that a visitor couldn’t just jump off. The only problem would be that if it fell back to earth, the shock wave would flatten 90% of the trees and buildings on the entire planet.

How do you calculate the number of combinations for e.g. a 3, 4 or 5 size cube?

Hi everyone, I am currently working on a project that would eventually create a Rubik’s Solving machine. We are in the programming stage and would like to know all the possible legal permutation and orientation of the 3 by 3 cube. i.e. so we can let the computer know what cases to ignore and what to consider.

Cheers!
