2x2 EG1 U 3 algorithm
2x2 EG1 U 3 algorithm: 7 turns, opening with F' U2 R. Case recognition, the complete sequence, and practical execution notes.
Solve the remaining 2x2 corners when the completed first face has an adjacent swap in its layer.
EG1 U 3 belongs to the U group in EG 1.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFR, UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: F F; R: R L; B: U U; L: R L. The letters identify colors by their reference faces.
Execute the algorithm
F' U2 R U2 R' U2 F
The opening is F' U2 R; the final segment is R' U2 F. This version contains 7 face, wide, or slice turns and no whole-puzzle rotations.
