I first obtained an East-sheen RD02 double 2x2x2 cube on Sat 23rd Aug 08. This is a tiny keychain of two 2x2x2 cubes that share a corner. I would've preferred a straightforward 2x2x2 but I'll take what comes across my path! A fascinating mechanism - there are only corner cubies! This can be quite confusing when you're only used to a 3x3x3 with its fixed centres. The two cubes sharing a corner made this a bit too fiddly to get serious with so I decided to wait 'til Xmas!
Dec 25th 2008: I received a white EastSheen 2x2x2 from puzl.co.uk as part of my self-directed set of Xmas presents and began my true exploration into this puzzle. The Eastsheen 2x2x2 has huge oversized cubies and is great quality -- it turns well from brand new and is a delight to handle. It suffers from the same annoyance of having pink opposite red instead of orange which can cause problems wih colour recognition. I recommend replacing the stickers with the proper colours from Cubesmith.
I'm terrible with algorithms so my 2x2x2 technique is a simplified 3x3x3 layer-by-layer method. With only 2 layers it takes the form of: -
Recently I've been trying to improve my 2x2x2 times by using the Ortega Method. It's not too hard to learn as it is basically the layer-by-layer method with one major shortcut and a few extra algorithms: -
Starting with week 33, I'm now using the Ortega method in the speedsolving.com weekly competition. I tis clear that I have a lot to learn as my times are similar to my LBL method although I am now colour neutral! A lot has to do with recognition of the PLL cases and I still make mistakes in the OLL stage!
As with a lot of these puzzles, speed comes with experience and recognition: here's some tips that I'm trying to follow myself! :-
OK, so being the geek that I am, I've created a nice printable OpenDocument drawing, with PDF and PNG versions: -
Feel free to copy them, change them, whatever you like! I think I got most of these algorithms from Erik's 2x2x2 pages - they seem to be down at the moment as he rebuilds his site: http://www.erikku.110mb.com
