OLL1 (a center dot)

(R U2’ R2 F R F’) U2’ (R’ F R F’) (bar on R&L-faces)

This is a symmetrical case, so I use only this one. It has Sledgehammer (R’ F R F’) two times and easy to turn and memorize.

Although I don’t use the following one, it is also easy to turn. Interestingly if you change r U’ r’ to r U r’, that is one of the algorithms for OLL2.

(R U’ R2’) D’ (r U’ r’) D (R2 U R’) (bar on F&B-faces)
