# 3LLL

From Speedsolving.com Wiki

The **3** **L**ook **L**ast **L**ayer involves completing the last layer in 3 steps or *looks*.

## 3-Look Last Layer Methods

- It usually consists of a 2-Look OLL, followed by a 1-Look PLL which requires knowledge of 31 algorithms in total (including mirrors) with an average of 26 moves. Sub 12 is possible with this 3LLL method.

- Another method is BLL, which is an LLEF followed by a OCLL-EPP and finally a CPLL which requires 26 algorithms in total (24 if excluding a possible reuse of an algorithm) with an average of 27 moves.

- ZZ-reduction is a ZZ variant that can be a 3LLL if employing superphasing. This consists of 1 algorithm to permute last layer edges, 7 OLL algorithms that preserve EP, and 4 PLL cases (Aa, Ab, E, H) for a total of 12 algorithms.

- Other 3LLL methods may exist.
