or solve online (using SudokuPad)
Theme: Line of Succession
Author/Opus: This is the 50th puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules (Insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Also, cells sharing a corner cannot contain the same number (as if adding a chess king’s move constraint to each cell). Also, if a white circle is given between two adjacent cells, then the two numbers in those cells must differ by 1. Pairs of cells without circles can have any relationship.
GAS Time Standards (highlight to view): Two party hats (🎩🥳): 8:00; One party hat (🥳): 16:00. All other solvers earn a 🦕: Micromanaging Microsaurops.
Thomas Hits the GAS (highlight to view): 2:17, with SudokuPad replay file shared as a download for now (requires loading via settings menu with improvements expected before people should use this regularly).
Solution: PDF; solving video with explanation to be added later from GAS team.
