Dot
DotNo yellow edges at all on the top face — only the centre. All four edges are flipped. Whatever the corners are doing in the picture is incidental; this step ignores them.
10 cases
Orient the last layer in two steps using ten algorithms instead of fifty-seven.
A route through OLL for people who do not want to learn 57 algorithms yet. First make the yellow cross with one of three algorithms, then orient the corners with one of seven. It costs a few moves and one extra pause compared with full OLL, and it gets you almost all of the benefit for a fifth of the memorisation.
No yellow edges at all on the top face — only the centre. All four edges are flipped. Whatever the corners are doing in the picture is incidental; this step ignores them.
A horizontal line of three yellow stickers across the middle of the top face: the left and right edges are already oriented. Read the edges only — the corners can be anything.
Two adjacent yellow edges with the centre, making a small L. As drawn the arms point to the right and towards you. As with the other two, only the edges matter here.
A bare yellow cross with a loose corner sticker at each end of the front face and each end of the back face. Nothing at all shows on the left or the right.
A bare cross with two yellow corner stickers sitting together on one side face — the left as drawn — and a single sticker at the far end of both the front and the back.
The cross plus both back corners, so the top shows a solid bar of three across the back. The front face carries a matching pair of yellow stickers — the headlights.
A fat bar down the right of the top face — the cross plus both right-hand corners. One lone yellow sticker sits at the left end of the back row and another at the left end of the front row.
The cross with two diagonally opposite corners already yellow. The two twisted corners show one sticker on the left face and one at the right-hand end of the front row, pointing away from each other.
The cross with exactly one corner already yellow. As drawn the finished corner is at the back right, and the other three show their yellow on the left face, at the left end of the front, and at the front end of the right face.
The cross with exactly one corner already yellow. As drawn the finished corner is at the front left, and the other three show yellow on the back face, on the right face and on the front face in turn.
