*** TODAY'S PUZZLE ***
Oh my goodness tonight's sudoku is a Worldie from Rosie called Feeling Rough. One look at the grid will hint at what's going on but figuring out how to actually enter anything is another challenge altogether. This is REALLY REALLY good.
Play the puzzle at the links below:
https://sudokupad.app/nmzsv3jbx9
Rules:
Normal sudoku rules apply. The grid is partially covered in fog. Placing a correct digit might clear some of the fog somewhere in the grid. No guessing is required. A digit in a circle indicates roughly how many circles contain that digit i.e. X in a circle indicates that X appears in either X+1 or X-1 circles (but not in exactly X circles). All circles are visible i.e. no circles are hidden behind fog. Orthogonally adjacent circles must have different entropy i.e. a digit from a different set {1, 2, 3}, {4, 5, 6}, or {7, 8, 9}. Digits along an arrow sum to the digit in the attached circle.
