The last-layer triangles are aligned with the U centre and everything below the U layer is solved. Orient the U corners without requiring their permutation. Orient the last three corners.

Proven optimum for every case.
5 writings are played from a representative position of the case. They reach the goal shown in the dialog without necessarily solving the whole puzzle.
Each case is drawn on a flat net of the puzzle’s faces. Grey marks the stickers that the case does not constrain.
Colours of the puzzle in the application. Grey marks what the case does not look at.
Lengths: each move counts 1, an inner slice 2, a rotation 0. The "setup" presents the puzzle as drawn and does not count.
In each case, the best available optimal algorithm comes first, then the others by increasing ease score. When no optimal writing is available, all algorithms are ranked by this score (lower is easier).
"Play" starts from a position of the case and runs the algorithm to the set’s goal. Usually, the starting position is obtained by running the algorithm backwards from the solved puzzle. For a partial goal, the player may start from a representative position of the case in the application; the puzzle is not necessarily fully solved at the end.
