  • Make cross (frur'u'f')
    • dot
      • frur'u'f' with any face
      • will lead to l shape
    • l shape 
      • frur'u'f' with one leg of l pointing towards you, and the other pointing to the right
      • will lead to line
    • line
      • frur'u'f' with line horizontal
      • will lead to cross
  • Align cross (ruur'u'ru'r')
    • two sides should be lined up
    • colors are on opposite ends
      • ruur'u'ru'r' hold with one color on front and one on back
      • will lead to colors at right angle
    • colors at right angle
      • ruur'u'ru'r' hold with one incorrect side on front and one on right
      • all four sides will be lined up
  • Place corners (l'uru'lur'u')
    • place corner piece in between the three correct centers, not necessarily correctly oriented
    • all corners incorrect
      • l'uru'lur'u' on any face
      • will lead to one corner correct
    • one corner correct
      • l'uru'lur'u' with correct corner on front right face
      • repeat once again.
      • will lead to Rotate corners
  • Rotate corners (ruur'u'ru'r'l'uulul'ul)
    • three corners incorrect
      • ruur'u'ru'r'l'uulul'ul with correct corner on front left
    • two incorrect corners on opposite corners
      • ruur'u'ru'r'l'uulul'ul with one incorrect corner on front right with top color facing right
      • will lead to two incorrect corners on same face
    • four incorrect corners
      • ruur'u'ru'r'l'uulul'ul with two corners incorrect with top color on front and back on the right face
      • repeat once again, will lead to two incorrect corners
    • two incorrect corners on same face with top color on front and back
      • ruur'u'ru'r'l'uulul'ul with two incorrect corners with top color on front and back on the right face
      • will lead to two incorrect corners on same face with top color on same face
    • two incorrect corners on same face with top color on same face
      • ruur'u'ru'r'l'uulul'ul with two incorrect corners on right
      • will correctly rotate the two corners
