# Puzzling Grids

## Solution

The title and flavour text hint at Binary Puzzle. The grid at the top looks like a Binary Puzzle module, so we should solve it first.

Note that the third row of this grid is relevant in the solution below.

The title also hints at Binary Grid, so we have to use its manual to solve the puzzle.

One of the secondary keys is labelled with the third row of the binary puzzle. By finding the letters in the bottom grid using the six black squares and reading them in reading order, we get the answer to the puzzle.
