The Most Extraordinary Sudoku In YEARS

** TODAY'S PUZZLE ** Mark was so convinced Simon would be blown away by tonight's sudoku that he asked him to open it live on camera. It's a Kaktuslav puzzle called Forcing but it's also mad. Despite being a "chaos construction" (ie a sudoku whose 9-cell regions can be any shape and need to be discovered rather than given as 3x3 boxes), the ruleset is just a single paragraph long. This has been hewn out of nature itself and is surely one of the most remarkable constructions we've ever showcased. Play the puzzle at the links below: https://sudokupad.app/jcdh680q0f Rules: Divide the grid into nine non-overlapping regions, each consisting of nine orthogonally connected cells. Place the digits 1–9 once each in every row, column, and region. In each region, place a circle in the leftmost cell of its topmost row. Every circled digit counts how many cells of its own region (including itself) are visible in its column (region borders block the view). The nine circled cells together form an extra region, i.e. they are orthogonally connected and contain the digits 1–9 once each. ▶CLASSIC SUDOKU 2: OUR BRAND NEW APP ◀ We've released the long-awaited sequel to one of our most popular apps (the original Classic Sudoku).
