OLL7 (Lightning shape)

(r U R’ U) (R U2′ r’) (vertical lightning shape & a block on R-face)

(l U L’ U) (L U2 l’) (vertical lightning shape & a block on L-face)

These are the reverse procedures of OLL6 (Square shape).

All 4 algorithms of OLL7 & OLL8 use Sune patterns, right & left hands, and back & forth start. Sometimes it is confusing which algorithm should be used.

The following tip is useful to avoid it.

1) which hand to turn first? -> hand on the side of a block.

2) which direction to turn first? -> toward the colored edge of Lightning.
