2x2 EG1 S 3 algorithm
2x2 EG1 S 3 algorithm: 10 turns, opening with y2 F 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 S 3 belongs to the S group in EG 1.
Recognize this starting position
In the inverse-derived training position, the upper-face color points upward at these corner positions: UFL. Reading each side’s upper corner stickers left to right when facing that side gives F: L U; R: F U; B: L U; L: R B. The letters identify colors by their reference faces.
Execute the algorithm
y2 F R' F' R U R' F' R2 U R'
The opening is y2 F R'; the final segment is R2 U R'. This version contains 10 face, wide, or slice turns and 1 whole-puzzle rotation.
