Author/Opus: This is the 86th puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Arrow Sudoku rules: Insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region).

Author/Opus: This is the 85th puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Arrow Sudoku rules: Insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). Some arrow shapes are in the grid; the sum of the numbers along the path of each arrow must equal the number in the circled cell. Numbers can repeat within an arrow shape. 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.

Today’s GAS features the full Battenburg dessert: the checkerboard clues show where an alternating even/odd pattern must appear and the absence of such clues indicates there is no such “pretty” pattern in that space.

Theme: Accentuate the Negative

Author/Opus: This is the 84th 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 a checkerboard clue appears at the intersection of four cells, the numbers in those cells must form a “checkerboard” pattern of odd and even (i.e., one diagonally opposite pair is odd and the other pair is even). All possible checkerboard clues have been given, so any sets of four cells without a clue cannot have a “checkerboard” pattern of odd and even.

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 8:00; One party hat (🥳): 15:00. All other solvers earn a 🦕: negative Neovenator.

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 a checkerboard clue appears at the intersection of four cells, the numbers in those cells must form a “checkerboard” pattern of odd and even (i.e., one diagonally opposite pair is odd and the other pair is even). Sets of cells without such a clue can have any arrangement of numbers and parities.

Sometimes the first workday after a long holiday (like the recent Thanksgiving in the US) can throw you for a loop. We don’t know if that is clover’s motivation today, but this combination of a Loop puzzle and a Sudoku will make you think more creatively than usual.

or solve online (using SudokuPad; this should now default to loading with the Pen tool on (people who already clicked may need to clear their browser cache for the short url). The pen tool looks like a square icon containing a circle and a bent line, next to the big 9 used to select the main number entry. Hitting those adjacent icons should let you alternate between entering numbers and loop segments. It is also at the top of the Settings menu (gear symbol) to turn on. Thanks to Michael in the comments for helping us get this on by default.)

Theme: Tangled Up in Loop

Author/Opus: This is the 81st puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

The loop must travel straight through every cell with an odd number and turn in every cell with an even number.

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.

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.

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.)
