Algorithm
Keyboard: U D L R F B turn a face, with Shift for the prime (U'). Y turns the whole cube. Backspace undoes.
Find the colours that moved. Which face has a stripe of another colour? The face that did NOT change colour in the middle of that stripe is the one that turned.
Reading a cube is a skill: a turned face keeps its own colour, while the four faces around it each get a stripe from a neighbour. Spotting which face turned — and which way — is how you check your moves when you follow an algorithm.
Chapter 1 — Learn the moves: Every move has a letter. Learn U, D, L, R, F and B, the prime (') and the double (2), and meet the three kinds of pieces.
