========== Introduction ========== In cubing, the term "metric" means a system for counting moves. The most famous and common one by far is OBTM (outer block turn metric, also known as HTM, half turn metric) as it is the wca's official metric for NxNxN puzzles. Other famous metrics include QTM...

So I have had a wondering of how various algorithms are made and why people use them. Some are generated. Some are discovered and popularized. For example, the lefty Nb perm is said to have less overwork then the righty Nb algorithm. Why is this and how does it affect speedcubing? How are these...

Hey guys, I need an optimal skewb scrambler (function or plugin - Lucas Garron, this would be a nice time to add skewb to Mark 2) written in Javascript, or at least how to write one. I'll be implementing the scrambler in MinimalisTimer. Thanks!

Hello, I recently found the Ribbon Cube on Google Play. It looks like a normal cube (Google Image Search 'Ribbon Cube') but the moves does not affect face you are turning around, this also enables 1/8th of a full turn. The app uses the equivalent of qtm when counting moves, ie it it counts half...

Someone recently posed a question to me: can you solve a 3x3x3 without turning one of the faces? To respond to this, I first tried to figure out how to perform an R' without turning the R face at all. After coming up with a 50 move intuitive solution, I ran a program on an Amazon server...
