GRCL Method

The Grant Rowan Connor Luna method, or GRCL (pronounced gurkle) is a combination of the best parts of several methods, including Grant’s OBC method, Rowan’s OBC method, Luna’s cell blockbuilding technique, and Connor Lindsay’s P4L algorithms. The name GRCL was proposed by Hypercubers Discord member Jasper on July 18 2022.


  • Orient Both Cells using either Grant’s method or Rowan’s method (whatever looks better in that particular scramble)
  • Separate the oriented colours of both cells while orienting 2 layers on those cells by holding the puzzle vertically and using Luna’s method
  • Permuate both layers of both cell using Rowan’s updated version of Connor’s P4L algorithms
