Plus, it's super engaging. Before you even try it (or find a method to help you solve it), it feels like it should be relatively easy to solve, right? After all, it's small enough to fit into your ...

No matter how mixed-up it is, the Rubik's Cube can be solved in 20 moves or fewer, say a team of researchers who used computer time donated by Google to run complex algorithms to prove it. That means ...

A Rubik’s cube solver has become the first person to show proof of successfully combining the final two steps of solving the mechanical puzzle into one move. The feat required the memorisation of ...

The Rubik’s Cube has only six faces, each presenting only nine cubelets, but the end result is to offer a mind-boggling number of permutations, only one of which embodies the desired solution. The ...

* First they divided the set of all possible starting configurations into 2.2 billion sets, each containing 19.5 billion configurations, according to how these configurations respond to a group of 10 ...
