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).
