Master Pyramorphix

The Mastermorphix (4-color version) is solveable just like the 3x3x3. but here is a small step by step guide that may help you based off of the petrus method!

build a 2x2x2 block

   * To do this first orient 3 centers in the proper direction (so you have yellow blue - blue red - red yellow) on the 3 edges going clockwise for example.
   * Now insert using f2l the corner with one of the edges (yellow red or blue)

   * repeat the above for the same corner 3 times (once for each edge.

Build the corner and 2 outer edges of 2 colors.

   * For example, build on yellow by placeing together one corner and 1 edge, then place the 2nd edge and insert into place on the yellow face. (This will take practice - you may end up with inversed triangle around your face - this is NOT PARITY) [Just reverse one of the edges i.e, 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.

Last Layer

   * For this step look at the actual orientation of the edges (correctly oriented vs. not oriented!)
   * Use the above to determine if you have the bar case; or the Crooked bar case
   * Think of the top layer as if it were the 3x3x3, turn the top layer 45degrees so you have it facing you just like a side on the 3x3x3
   * Remember! there are 2 sets of 2 identically colored edges! (use this to your advantage - U-perms)

Notes:

   * Rotate one center 180degrees ( [R U R' U]x6 ) - this will keep all other pieces oriented.
   * Rotate one corner 120degrees ( [L' U' L U] [L' U2' L] [R U R' U R U2' R'] )
