Build the left 1×2×3 block
Roux starts by building a 1×2×3 brick on the left: the red center, three red edges (white-red on the bottom, green-red at the front, blue-red at the back) and the two white corners between them. Hold the cube white-down, green-front, and keep it that way. The lessons go from “what even is a block” to full solves: identify the pieces, build a 1×2×2 square, expand it, then handle real scrambles.

Practice from real scrambles
Fresh random scramble every attempt. Build the left 1×2×3 block by tapping moves (or keyboard on desktop) — the trainer checks the real cube state after every move and tells you when the block is done.
