Apprends le langage du cube. Comprends ce que signifient R, U, L, D, F et B.
Pour lire les algorithmes et résoudre le cube, tu dois comprendre la notation standard. Chaque lettre désigne une face du cube et comment la tourner.
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.
Mouvements de Base
Une lettre seule signifie un quart de tour dans le sens horaire. Une lettre suivie d'une apostrophe (par exemple R') signifie un quart de tour dans le sens antihoraire. Une lettre suivie d'un « 2 » (par exemple R2) signifie un demi-tour.

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
Mouvements Larges
Une minuscule ou le suffixe « w » signifie tourner cette face plus la tranche intérieure adjacente ensemble.
RwFace droite + tranche centrale (identique à r).
UwFace du haut + deuxième couche (identique à u).
Mouvements de Tranche
Couches intérieures uniques, sans toucher aucune face extérieure.
MTranche centrale, même direction que L.
ETranche équatoriale, même direction que D.
STranche verticale (standing), même direction que F.
Rotations du Cube
Fais pivoter tout le cube sans tourner aucune face.
xFais pivoter tout le cube sur l'axe R (comme un mouvement R).
yFais pivoter tout le cube sur l'axe U (comme un mouvement U).
zFais pivoter tout le cube sur l'axe F (comme un mouvement 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.
