Impara il linguaggio del cubo. Capisci cosa significano R, U, L, D, F e B.
Per leggere gli algoritmi e risolvere il cubo, devi capire la notazione standard. Ogni lettera indica una faccia del cubo e come ruotarla.
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.
Mosse di Base
Una lettera da sola significa un quarto di giro in senso orario. Una lettera seguita da un apostrofo (ad esempio R') significa un quarto di giro in senso antiorario. Una lettera seguita da un «2» (ad esempio R2) significa un mezzo giro.
R
Ruota la faccia Destra in senso orario.
R'antiorario
R2180°
L

U
Ruota la faccia Superiore (alto) in senso orario.
U'antiorario

D
Ruota la faccia Inferiore (basso) in senso orario.
D'antiorario
D2180°
F
Ruota la faccia Frontale in senso orario.
F'antiorario
F2180°
B
Ruota la faccia Posteriore in senso orario.

R
Nessun modificatore
Orario 90 gradi
R'
Antiorario (apostrofo) — es. R'
Antiorario 90 gradi
R2
Mezzo giro — es. R2
180 gradi (in qualsiasi direzione)
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
Mosse Larghe
La minuscola o il suffisso «w» significa ruotare quella faccia più la fetta interna adiacente insieme.
RwFaccia destra + fetta centrale (uguale a r).
UwFaccia superiore + secondo strato (uguale a u).
Mosse di Fetta
Singoli strati interni, senza toccare alcuna faccia esterna.
MStrato centrale, stessa direzione di L.
EStrato equatoriale, stessa direzione di D.
SStrato verticale (standing), stessa direzione di F.
Rotazioni del Cubo
Ruota l'intero cubo senza girare alcuna faccia.
xRuota l'intero cubo sull'asse R (come una mossa R).
yRuota l'intero cubo sull'asse U (come una mossa U).
zRuota l'intero cubo sull'asse F (come una mossa F).
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.
