Lets play a game.
It's like bitcoin mining but for your mind.
I have deposited $5 (USD) of bitcoin into a paper wallet. The private keys to the wallet can be determined by solving my puzzle below. If you are the first to solve the puzzle you own the wallet keys and can take the money.
This is a grid-shading puzzle, each square is either black or white. Some of the black squares have already been filled in for you.
Each row or column is labelled with a string of numbers. The numbers indicate the length of all consecutive runs of black squares, and are displayed in the order that the runs appear in that line. For example, a label "3 1 2" indicates sets of three, one and two black squares in that line, each of which will have at least one white square separating them (but may be more).
To claim your prize simply sweep the contents of the paper wallet into your wallet. To sweep private keys in an electrum wallet go to Wallet menu -> Private Keys -> Sweep. Enter the private keys in the appropriate field. Leave the ‘Address’ field unchanged. That is the destination address and it’ll be from your existing electrum wallet.
Important! - Others may get the private keys to this wallet. Don't keep any bitcoins in there!
If you were the first and won the prize comment below. I will be keeping an eye on the contents as well and will let everyone know when they are gone.
I think this will take a fair while to solve (it certainly took a fair while to make).
well even if I solve this I can't scan QR codes...nice nonetheless
found a way to scan without phone lol... https://webqr.com/
Sudoku on steroids
why not? Any mobile phone QR scanner will work.
derp my screen too small and I don't have a smartphone
Has anyone claimed this yet? I tried to solve offline, and ran into dead end, must have made a mistake and can't figure it out...
Might I ask for help on the right side lol...
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...
