This resolves to PROB = Percentage of humans able to solve easy Sudoku puzzles
Standard 9-by-9 Sudokus, comparable in difficulty to easy games on https://www.latimes.com/games/sudoku
No help may be used for the mental task of solving the Sudoku, meaning "just pen and paper allowed" in most cases, definitely no solvers, counseling, tutorials, training, strategy guides, etc. Explaining the rules is allowed.
Those criteria are not final. I'm trying to keep a wider range of options on how to tighten this up with additional criteria by waiting for some community feedback. I'd advice against huge bets for now. The question's intent is to find the share of humans able to solve an easy Sudoku in a reasonable setting with reasonable incentives. The close date might be postponed if, by my judgement, there is reason to believe we will get important data, for example via some study.
Questions and suggestions concerning resolution criteria are welcome and encouraged!
