The Ja perm
The two back corners trade places, and so do the back and left edges. 11 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 two back corners trade places, and so do the back and left edges. This is the Ja permutation, one of the twenty-one ways an oriented last layer can still be shuffled.
Turn the cube in your fingers and look for a solid bar of one colour runs across the front.
On average one solve in eighteen ends here. The algorithm runs 11 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.
