If you watch the piece this takes the two of them, splits them rotates them, and aligns them reorientated on the top layer. The Block's unique mechanism and different sized blocks result in the Cube changing shape with every move you make. You may recognise this as the Mirror Cube – but add some recognisable Rubik’s colours and this makes for an exciting new addition to the range.

Rubik’s Blocks, Original 3x3 Cube with a Twist Challenging

With 4 flipped edges I rotate the middle vertical slice 90 degrees, rotating the bottom edges into the front. Once the bottom edge pieces are put in place, either one or three edge pieces are flipped, due to the flipped medge. But if you want something that doesn't touch the F2L at all AND is quick to execute, then you'll have a harder time finding them. If the first 4 bottom slice turns were 3 clockwise and one counterclockwise, the next 4 need to be 3 counterclockwise turns followed by a clockwise one.Solving the Mirror Cube is exactly the same as solving the Rubik's Cube, however it is harder to identify each part because the size difference between the puzzle's parts is less obvious than the color difference of the original puzzle's stickers. An intuitive solution is to remove both the corner and edge, splitting them up, then move them back in an intelligent way. When only 2 edges need flipping I orient them so they are in the bottom opposite one another, one in the bottom front of the cube, the other at the back. A way to solve this is to replace the flipped edge by a random block and then put the edge at its right place.

Rubiks | Solve it

I rotate the medge piece into the final layer and in the process rotate a placed/oriented piece out of the final layer. Simply rotate the medge that needs flipping into the unsolved layer and perform the double edge flip as described above. This is done to create either 4 flipped edges, in the bottom layer, or 2 flipped edges, opposite one another. I personally put a random buffer-piece in and then solve it, the thing you want to prevent (hence this comment instead of an answer). While having the exact same mechanism, the Rubik's Cube parts all have the same size but differ from one another with the help of colorful stickers, the Mirror Cube is the exact opposite.You now need to rotate the moved middle edge back into the middle slice and in the process the relocated bottom edge back into the lower slice. Additionally, it is not nearly as efficient as simply removing the corner/edge pair, since you'd have to do this anyway to solve F2L from this position. Then the vertical slice is rotated once more but the bottom slice on the fourth rotation is turned opposite to the previous three times.
