Seven "Eight" Nine
(Published on 1. October 2024, 18:53 by TimmyTpickle)
This puzzle idea comes from the classic English joke, "Why was 6 afraid of 7? Because 789."
Rules:
Normal sudoku rules apply.
Fog of War: The grid is covered in fog. Placing correct digits in the grid clears the fog in the surrounding 3x3 area. No guessing is required.
Killer Cages: Digits in a cage may not repeat, and the digits' values sum to the indicated total.
Modular Lines: Along a modular line, the set of digits in any run of three cells must contain one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
Six Is Afraid of Seven: The digit 6 cannot be adjacent to the digit 7 (orthogonally or diagonally.)
Because...
Seven "Eight" Nine: The value of any 9 digit orthogonally connected to at least one 7 digit is 0.
