The brute-force-method caused a major headache but it works! I can solve all Sudokus in theory, but for more than a couple 0s, it takes longer than a few seconds. I’m generating a list of 0s and their possible numbers, then recursively trying out all possible combinations. So far without “cleaning up” the list as the process happens, so it’s highly ineffective. My next goal would be to manage solving any board in an “awaitable” time.
