pairing up edges and wings can be done almost entirely with the method shown below, the idea is a very familiar one to cubers, fix something, replace it with something else that isn't fixed to move it out of the way, then restore what part of the centers were broke while pairing up the edge and wing. this is a great beginner method as you don't have too much to keep track of, and after every piece the centers are brought back to solved state, so cube rotations aren't a problem.
this method is the advanced method for pairing up the tredges. it is faster, but requires great look ahead and recognition. it also allows for the centers to be off after each piece, so any mistakes can result in the centers being messed up again, usually resulting from a cube rotation, or a deep cut. The idea is to use the M or E ring (as you prefer) to pair up the wings with their matching edges, then "store" the completed tredges on the L and R (or U and D) faces depending on the building area you use. at this time i know most of the top solvers are using the E area for building and storing on U and D. for this reason i will show it like this, but the M ring and storing on L and R is also very usable for great times. Once you have eight sets of tredges stored you go on to solve the last four in groups of one or two if you can. this applet will give you a single edge view, for a compete walkthrough, check out this video.
last edge groups
now when you get to the last two, three, or four sets of tredges, this can get a little tight because there is not always an extra set of pieces to trade out, but these can be fixed easily with some of the following algorithms in the complete last two tredges index. There are also other useful algs included that work on more than one or two edges, allowing for a faster resolution of the last four tredges.
|first 8 edges progress gauge|
|master edges||<45||every turn is optimized to postition or match pieces up, there is no delay between peices, and a consistent smoothness is there while solving, the last 4 edges are solved more efficiently, fixing as many things at once as possible.|
|intermediate edges||<90||finding pieces is getting faster, but there are still delays between some pieces. try slowing down and optimizing moves, all insertions can be 3 or 4 moves. again smoothness is the key, speed comes automatically when you you're smooth. last 4 edges are probably being solved one at a time, experiment with last 2 edge algs and commutators to really improve.|
|beginner edges||>90||it is difficult to find matching groups and delays between every piece. try solving a specfic set for a while (like all the orange or white edges) to improve finding ability and learn insertions.|
