Today marks our 100th Mini Sudoku post on LinkedIn. If I had a paperclip for every time someone has played Mini Sudoku over that time, my guess is I’d have somewhere between 100 million and a billion paperclips? That seems pretty cool. (Note to self: never become a billionaire in the currency of paperclips.)

While the variant name seems like a mouthful, it comes from the origin with an anti-rule that doesn’t apply here. Today, just recognize that arrow clues describe increasing or decreasing series for the first three numbers in that direction.

Theme: The Barber of Seville

Author/Opus: This is the 77th 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 4 means R4C1 < R4C2 < R4C3 and the arrow at the left of row 9 means R9C1 > R9C2 > R9C3. (The absence of an outside arrow clue has no meaning in this puzzle unlike “standard” Rossini Sudoku.)

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 6:00; One party hat (🥳): 11:00. All other solvers earn a 🦕: operatic Orkoraptor.

Thomas Hits the GAS (highlight to view): 1:40, with SudokuPad replay file shared as a download for now (requires loading via settings menu with improvements expected before people should use this regularly).

If you really care about symmetry, then you might think Bill’s theme here is a B A D I D E A as the patterned clues outside the grid seem to be missing something. We expect you’ll find today’s GAS to be G R E A T anyway.
