# 4x4 PLL Parity

When you are solving a 4x4, PLL parity can significantly slow down a solve. Luckily, there are some tricks you can use to minimize the damage without learning too mamny new algorithms.

Some algorithms in this set are similar to PLL algorithms you already know, except there is a parity algorithm mixed in. By doing the parity algorithm strategically, you can turn a slow PLL into a fast PLL.
