ZBLL (short for Zborowski-Bruchem Last Layer) is a step of a method which involves solving the entire last layer in one step, assuming that the edges are already oriented. This is part of the ZB method, but it can be useful for any other method which leaves the edges of the last layer oriented after F2L is solved (such as the Petrus method).ZBLL indeed sounds like a very useful step to learn, but the main reason that it is not in wide use is that it involves a massive 177 algorithms (counting inverses and mirrors are the same), or a total of 493 cases (including PLL). Only a handful of people have ever learned this step in its entirety. If you wish to learn it, it is useful to start by learning either OCLL/PLL or COLL/EPLL, so that you will always be able to finish the cube relatively quickly even if you do not yet know the ZBLL case.
英文水平拙计 蹩脚翻译了下
ZBLL(Zborowski-Bruchem Last Layer)是一种方法,它是让(魔方)的最后一层一步到位的方法,假设所有棱块色向都已经是对的。这是的ZB体系的一部分,但它可以是对于任何其他最后复原F2L以后所有棱色相都正确的解决方法(这里不知道什么意思。。应该指要用到F2L的吧)
