Chapter 6: Finish the cube · Level 17 of 20

Level 17: Top edges: the last swap

Goal: Cycle three top edges into place with R U' R U R U R U' R' U' R2 and solve the cube. 2 tasks · ★★★ = fewest moves.

Task 1 of 2

The solved bar is at the back. Do the algorithm to solve the cube!

Your cube, unfolded

Goal

Your moves

Algorithm

    Keyboard: U D L R F B turn a face, with Shift for the prime (U'). Y turns the whole cube. Backspace undoes.

    💡 Need a hint?

    Find the side whose top edge already matches (a full bar of one colour). Hold that side at the BACK and do R U' R U R U R U' R' U' R2. If the edges went the wrong way round, do it once more.

    What you learn here

    The corners are done, so only the top edges are left. Usually one edge is already right: its side is a full bar. Hold the bar at the back; the algorithm moves the other three edges round in a circle. Do it once or twice — and the cube is solved!

    Algorithm: R U' R U R U R U' R' U' R2

    Chapter 6 — Finish the cube: Move the top corners, then the top edges, to their places — and the cube is solved.
