The H perm
The front and back edges trade places, and so do the left and right edges. Seven moves put every piece home.
The last layer is all yellow on top, and every piece of the first two layers is home. What remains is position: the front and back edges trade places, and so do the left and right edges. This is the H permutation, one of the twenty-one ways an oriented last layer can still be shuffled.
Turn the cube in your fingers and look for headlights, a matching pair split by an odd sticker, face the front and the right and the back and the left.
On average one solve in seventy-two ends here. The algorithm runs seven moves; play it slowly first, then step through it turn by turn with your own cube in hand.
Checked by simulation before publishing: the position shown plus the moves shown must produce a finished cube, and the algorithm must touch nothing outside its own job. The diagram and the player are drawn from the same simulated position, so they cannot disagree.
