Theme: Nesting Birds

Author/Opus: This is the 61st puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: This puzzle combines three grids and rule sets. Within each grid, each cell will contain a number from 1-N (either 1-5, 1-7, or 1-9) so that each row, column, and in the larger grids each outlined region has all the numbers exactly once. The top and bottom rows of these grids overlap as shown (including along the dotted lines); the same numbers complete the respective spaces of two grids.

1-5 Latin Square with Thermo rule: Numbers must be strictly increasing from the round bulb to the flat end of each thermometer shape.

1-7 Sudoku with Kropki Pairs rule: If a white circle is given between two adjacent cells, then the two numbers in those cells must differ by 1. If a black circle is given between two adjacent cells, then the two numbers must have a ratio of 2. Pairs of cells without circles can have any relationship.

1-9 Classic Sudoku: Follows the basic number entry rules above with no extra rules.

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 12:00; One party hat (🥳): 25:00. All other solvers earn a 🦕: Thankful Thotobolosaurus.

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).

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.

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.)
