I've Solved a Rubiks Cube
This may not be a major feat for some people, but I can now say that I've successfully completed a jumbled up Rubiks cube without resorting to peeling off the stickers...
Unfortunately, it wasn't all down to my own brilliant mind. I had a little help. Whilst this isn't the quickest or most efficient methods, at least it worked for me and now I can say I've done it.
Next challenge, try and do it myself without any help - one day :-)
