Green level 48 solution or walkthrough

I don't understand this

Someone explain plz!??!?!?!?

This doesn't make sense and the answer you replied to others here doesn't make sense either.

I see the pairs, but how do you know which pairs to select next? The two blocks have the same number of trees and branch stack, but they don't point in the same direction or even at the same block

This makes no sense. Your reply to everybody doesn't make sense either.

Okay, the explanations on this video are horrible, so here’s my take.
(For reference, when I refer to ‘boxes’ it means the black squares only, while if I use ‘squares’ it means both the black boxes AND the green spaces inbetween. Also, I call the indicators ‘trees’, but you could also call them arrows).

Each box has one or two trees attached.
Let’s use the top box of the first left column as our first example.
It has a tree with two branches on the right side of the box, and a one branch tree on the bottom. This is ‘pointing’ at a specific square, which is exactly two squares to the right and then one down from the original.
You can also count one down and two right, as it doesn’t matter what order you count in, you should reach the same square regardless.

Another one is the right box of the top row. With a single branch tree pointing to the left, and a two branch pointing down, it leads you one square to the left and two down, which happens to be the same square the first example led to as well.

They both point to the same place, so that makes them a pair. Basically, your job is to find two boxes that both point to the same square like this.
Enjoy.

A full video should be provided for this. There are too many images looming above the directions that it's impossible to follow the solution!
