As any member of the PSE community knows, grid-deduction puzzles really aren't my forte.
In fact, I'd like to share one particularly disasterous attempt at designing a Slitherlink puzzle.
Disclaimer: This is a fictional story
So, I was working on a slitherlink late one night, and when I woke up, I realised that my sleepiness had caused me to put some wrong numbers into the puzzle! I had only miscounted these clues by one, but they were wrong nonetheless.
I took a sip of coffee to wake me up, and then I noticed something interesting about the way I messed up the puzzle. I had gotten exactly one clue in every row and column misnumbered by one!
In my excitement in thinking that the puzzle was salvagable, I stood up, and accidentally tipped my coffee onto the puzzle!!!
This rendered some clues unreadable, and I couldn't remember if some of the now unreadable clues were the ones that were wrong or not.
After finishing my coffee, I realised that this was still a solveable puzzle.
There's my slitherlink puzzle, after being misnumbered AND having some clues (possibly correct, possibly misnumbered) destroyed by my morning coffee.
Can you find the intended answer to the slitherlink?
