The file contains a hint and a bi-directional array. You have to check for each position in the array all the numbers in the sorrounding, considering only values sorrounded by *even* numbers.
You can write a [script](https://raw.githubusercontent.com/m3ssap0/CTF-Writeups/master/DarkCTF%202020/Minesweeper/minesweeper.py) to solve it.
