Semi-official results

Official cubing competitions are run by the world cube association (WCA), but there are many more puzzles out there than the ones the WCA officially recognises. This is not because the WCA hates the other puzzles, just that being an official governing body of a billion different puzzle types is hard.

Because people still get competitive about the other puzzles they like to solve, there's a website called cubing contests where rankings for other popular puzzles are posted. There are different categories as well, depending on how "official" the result is (did you do it at home, or at a judged competition?)

Personally, I have only competed in one unofficial event, which is 15-puzzle. Individuals do not have cubingcontest profiles, so let me just point you to the UK 15-puzzle rankings and you can check for yourself whether I'm still joint 3rd in the country alongside shadowslice!
