(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
Following an earlier puzzle this week, today the Rossini rules are in full effect meaning there is an inverse rule and non-arrow rows/columns cannot have any of Rossini’s trademark crescendos/decrescendos in the form of increasing or decreasing series of numbers.

Theme: William Tell

Author/Opus: This is the 78th puzzle from Clover, 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). Whenever an arrow is given outside the grid, the first three numbers in that row or column must increase in the direction of the arrow. For example, the arrow at the left of row 3 means R3C1 < R3C2 < R3C3. Also, all possible arrows have been given so where there are no arrows on the outside there cannot be an increasing or decreasing series (i.e., the middle number is the largest or smallest of the set of three numbers). GAS Time Standards (highlight to view): Two party hats (🎩🥳): 7:30; One party hat (🥳): 14:00. All other solvers earn a 🦕: romantic Rhabdodon.

Thomas Hits the GAS (highlight to view): 3:00, 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.
