# Minesweeper
> Category: Misc> Description: ```I'm lucky to be surrounded by even-minded people from all around. Flag is not in the regular format.Submit flag in darkCTF{flag} format.```
# Analysis
From the provided file we have an array of arrays (matrix) and the challenge name points us to `Minesweeper` (I'm going to assume you know what this game is, if not please check this out https://www.microsoft.com/en-us/p/minesweeper-free/9wzdncrdk4km?activetab=pivot:overviewtab ).
```I'am lucky to be surrounded by even-minded people from all directions.Flag is not in the regular format.array = [[93, 91, 95,... 71], [83, 89, 73, ..., 69], ... ]```
So, it's pretty obvious this is not a coincidence, also from the description you read that 'surrounded by even-minded people', this called my attention and my initial though was that this was the 'bomb' condition.
So, I would have to find all cells that are fully surrounded by even numbers? Those then would be converte to ascii and hopefully I get something.This was the thought process, although you'd have to 'guess' the logic, it's kind of obvious in my opinion (save time, agree with me).
# Solve
I removed all text from minesweeper file and left only the `array = [` instruction, that way I can just load that to python (lazy I know, but works)
```python
with open('minesweeper', 'r') as fd:    line = fd.readline()    while line:                exec(line)        line = fd.readline()
arr = []
for x in range(len(array)):        print('Processing row {}'.format(x))
    if x == 0 or x == len(array) - 1:        print('Skipping row {}'.format(x))        continue     for y in range(len(array[x])):            print('Processing column {}'.format(y))
        if y == 0 or y == len(array[x]) - 1:            print('Skipping cell {},{}'.format(x,y))            continue         up = x - 1        down = x + 1        left = y - 1        right = y + 1
        if array[up][y] % 2 == 0 and array[down][y] % 2 == 0 and array[x][left] % 2 == 0 and array[x][right] % 2 == 0 \            and array[up][left] % 2 == 0 and array[up][right] % 2 == 0 and array[down][left] % 2 == 0 and array[down][right] % 2 == 0:                       # surrounded by even-minded cells, I must be relevant            arr.append(array[x][y])
print(arr)```
```... # several debug lines ommittedProcessing column 39Skipping cell 50,39Processing row 51Skipping row 51FLaGISYOUHaVEOBSERVaTIONaNDPaTIENCE```
From the found text the flag was `darkCTF{YOUHaVEOBSERVaTIONaNDPaTIENCE}`.
