Ragetester. The prize is still not claimed. Based on the number of votes of this post I would say there would not be many trying.

My only tip at this stage is that it's just as important to mark the blanks as it is to mark the blacks. For example if you have a run of 4 blacks and you know that there couldn't possibly be another black after it (because the list says 4) then put a mark in that square so that when you are looking from another direction you can use it to help you.

And never mark a square unless you are 100% sure of it. Making assumptions at the start could lead to a big problems and it's very hard to back track.

It should be solvable. I did it using Excel with conditional formatting and a couple formulas to help check things along the way.

If no one has made progress by tomorrow I might post some more squares so its a bit easier.

I ended up erasing a part or what was the biggest mess...and tactics with covering used numbers backfired...
not sure I can finish this, here is what I got now, I don't care if someone uses my progress:

well done ragetester. you made it a fair way.

unfortunately i can't give away too much because there may be others working on it in secret.
I have put a yellow dot on the squares that are not correct.

If i do another one in the future I will make it a bit easier. I know it takes a very long time to solve. However this post doesn't look like it will get much of a payout so I probably wont do many more.

I hope you enjoyed the challenge in getting as far as you did.

Oh my, I was sure those were correct...
Challenge was interesting, but as I said it didn't even fit my laptop screen, had to scroll up/down...
All the upvotes here on steemit are a nice reward, I never tried paper wallets, don't want to make you pay any fees that are not required...
In the end I failed to solve it...
