Lär dig kubens språk. Förstå vad R, U, L, D, F och B betyder.
För att läsa algoritmer och lösa kuben måste du förstå standardnotationen. Varje bokstav syftar på en sida av kuben och hur man vrider den.
Hold the cube the same way every time
Before any letter means anything, agree on how you are holding the cube. Pick up the cube with one colour on top (this becomes U, Up) and one colour facing you (this becomes F, Front). The other four faces fall into place: the face on your right is R, on your left L, away from you B (Back), and underneath D (Down). Hold it like this and the six letters never change meaning, no matter how scrambled the cube is.
The standard view: U on top, F toward you, R on your right. Every algorithm assumes you are holding the cube this way.
Grunddrag
En bokstav ensam betyder ett kvarts varv medurs. En bokstav följd av en apostrof (t.ex. R') betyder ett kvarts varv moturs. En bokstav följd av en ”2” (t.ex. R2) betyder ett halvt varv.

A single R turn, looping. Watch the top-right edge swing away from you — that is clockwise.
Read a real algorithm
Reading an algorithm is just two questions, one move at a time: which layer (the letter) and how does it turn (the symbol). Nothing more. Let's decode the most famous beginner trigger on the cube — the Sune, named by Swedish speedcuber Lars Petrus. It twists three corners and reads like this:
Watch it run, then read the seven tokens left to right against the list.
R — no symbol, so turn the right layer 90° clockwise.
U — no symbol, turn the up layer clockwise.
R' — the prime means turn the right layer 90° counter-clockwise.
U — up layer clockwise again.
R — right layer clockwise.
U2 — the 2 means a 180° turn of the up layer.
R' — right layer counter-clockwise to finish.
Naming pieces and slots
The same six letters name the pieces too, by listing the faces a piece touches. An edge touches two faces (the edge between U and F is UF); a corner touches three (the corner of U, R and F is URF). For a piece, order doesn't matter — FR and RF are the same edge. But corner names are read clockwise, so URF, RFU and FUR all name the same corner. When you need to talk about a single sticker, the first letter is the face you are looking at: the U-sticker of that corner leads with U.
UFedge — touches 2 faces (order doesn't matter)
URFcorner — touches 3 faces, read clockwise
Breda drag
En liten bokstav eller suffixet ”w” betyder att vrida den sidan plus det intilliggande inre lagret tillsammans.
RwHöger sida + mittlager (samma som r).
UwÖvre sidan + andra lagret (samma som u).
Lagerdrag
Enskilda inre lager, utan att röra någon yttre sida.
MMittlager, samma riktning som L.
EEkvatorlager, samma riktning som D.
SStående lager, samma riktning som F.
Kubrotationer
Rotera hela kuben utan att vrida någon sida.
xRotera hela kuben på R-axeln (som ett R-drag).
yRotera hela kuben på U-axeln (som ett U-drag).
zRotera hela kuben på F-axeln (som ett F-drag).
The three notation mix-ups everyone hits
M “looks backwards.” The middle slice M follows the L face, not R — so an M turn goes the opposite way to what you'd expect from R. Judge slice direction by the left face.
Lowercase isn't a secret move. On a 3×3, u and Uw are the same thing (a wide turn). It only changes meaning on bigger cubes.
A double turn has no “wrong” direction.R2 and R2' end in the same state; the prime only tells your hands which way to spin.
