The

**Mastermorphinx**is a tetrahedral shape mod of a 3x3x3 Rubik's Cube.## StepsEdit

Here is a small step by step guide, based off of the Petrus Method, that may help you:

### #1 - Build a "cross"Edit

- To do this, first orient 3 centers in the proper direction (so you have yellow to blue, blue to red, red to yellow) on the 3 edges going clockwise.
- Now insert (using F2L,) the corner with one of the edges (yellow, red, or blue)
- Repeat the step above for the same corner 3 times (once for each edge).

### #2 - Build the corner and 2 outer edges of 2 colorsEdit

- Place together one corner and edge, and then place the second edge and insert them into place.
- This may take some practice. You may end up with it inversed, but it is not a parity. Just reverse one of the edges with the following algorithm: R U2 R' U2 L U' L'.

- Build this on 2 of the colors from your 2x2x2 block (red/blue/yellow in this case).
- Insert the last F2L pair if required.

### #3 - Build the last layerEdit

- Make sure that the edges are correctly oriented, and detemine if you have the bar case or the crooked bar case.
- Think of the top layer as if it were the regular Rubik's Cube. Turn the top layer 45 degrees so you have it facing you just like a side on the Rubik's Cube.
- Remember! There are 2 sets of 2 identically colored edges! Use this to your advantage (U-perms).

## TipsEdit

- To rotate one center 180 degrees, use the following algorithm: [R U R' U] x6. This will keep all other pieces oriented.
- To rotate one corner 120 degrees, use the following algorithm: [L' U' L U] [L' U2' L] [R U R' U R U2' R'].
- Some notable algorithms from 3x3x3 include:
- J-Perms
- T-Perm
- U-Perms
- A-perms
- 2-look OLL cases (Sune/Bar/L-shape)
