This puzzle has been out for at least a week. I want to use the table for other things.
Resolves YES if fully solved and/or no more unsolved pieces exist. (If some pieces are missing because the puzzle isn't a complete set or because we lost some pieces, solving it as much as possible counts.) If I am cognizant of them solving the puzzle, I will immediately resolve this YES.
Resolves NO if I am confident they have given up or if they do not finish it by the end of the month.
Resolves N/A if a puzzle solver requests this market canceled. They don't know about this market at time of market creation.
I may provide status updates at whatever time intervals I choose. I am not actively trying to solve this puzzle.
The puzzle solvers are not active Manifold users. I will not trade on this market. Therefore, I believe traders need not worry about insider trading.
Initial state:

@retr0id I can't say for certain, but I want to say about 2 days ago? Maybe? Certainly last weekend they were attacking it.
