### Crazy 3x3x3 Mercury - Reduction

The Crazy 3x3x3 Mercury is one of the "Crazy Planet Cube" series.

This solve will be using a Reduction method, where we reduce the cube to a circle cube. This means we'll first place the circle edges, then solve the outer edges, and then attach the circle corners to their respective outer edges. Once that's done, we'll complete the solve as we would for a circle cube, by solving the outer corners.

Understanding Crazy 3x3x3 Mercury

First, take a look at the diagram below.

You'll see that Mercury is listed as "1", and on the picture, the white face is different to the other 5 faces. The "1" means that when you turn the white face, the center parts turn with the face. When you turn the other faces, the center parts do not move. So they're "0" faces.

But yours may have a different colour as the "1" face. (Apparently the factory just puts them together with the correct face specification regardless of colour.) It's a good idea to make yours the same colour specifications as the original. This site will be using the correct colours. This video will show you how.

The Basic Plot
1. Solve circle edges
2. Solve outer edges
3. Attach circle corners to outer edges
4. Solve outer corners
Step 1: Solve Circle Edges

Solving the circle edges on this cube is particularly simple. We place the yellow edges first and then hold the cube with the white face on the bottom. Turn in the middle layer edges using the white face. Once they are all done, the upper and lower layer edges will turn into place with at most two turns. This is because they cannot leave their orbits.

Step 2: Solve Outer Edges

The outer edges are also straightforward. We use edge piece series, and make sure not to turn the white face.

Step 3: Attach Circle Corners to Outer Edges

This is the longest part of the solve. It is, however, still quite simple. The goal is to attach the circle corners to their outer edges.

We'll make use of a circle corner 3-cycle with which we can attach all the circle corners to their outer edges.

First, attach the upper layer circle corners. Next, attach the lower layer circle corners. Do this by turning the cube over so that the white face is on the top. But before attaching the circle corners, turn the middle vertical slice so that the white center is on the bottom.

Once the upper and lower layer circle corners are attached, the only circle corners left are those on the white and yellow (top and bottom) faces.

Step 4: Solve Outer Corners

At this stage, we have what is equivalent to a circle cube. The only things left to solve are the outer corners. We place these using corner piece series, and make sure we don't turn the white face while doing it.

And that's it. Your Crazy 3x3x3 Mercury is now solved. I trust this site has been helpful. If you have any questions or want some clarifications, please use the comments to do so.
