Author/Opus: This is the 153rd puzzle from Clover, part of the Genuinely Approachable Sudoku (GAS) team.

Sandwich Sudoku by Philip Newman

(This post is part of the Genuinely Approachable Sudoku (GAS) series.)
Sometimes a good old-fashioned PB&J hits the spot. As a toddler, my wife actually ate PB&Js — with a side of grapes and cheese puffs — every. Single. Day. If peanut butter and jelly sounds good to you right about now, then it’s time to gobble up this Sandwich Sudoku.

Theme: Peanut Butter Jelly Time

Author/Opus: This is the 133rd 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). A value outside of the grid is a sandwich clue — it tells you the sum of the digits between the 1 and the 9 in that row or column, not including the 1 and 9 themselves.

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 10:00; One party hat (🥳): 20:00. All other solvers earn a 🦕: Xylophonic Xianshanosaurus.

Author/Opus: This is the 131st puzzle from Bill Murphy, 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, an arithmetic series must be formed along each line so that numbers in adjacent cells have the same difference. Different lines may have different common differences. (For example, a sequence line could be 1-2-3-4 (difference of 1), 1-5-9 (difference of 4), or even 5-5-5 (difference of 0) as long as it obeys other Sudoku rules.)

GAS Time Standards (highlight to view): Two party hats (🎩🥳): 7:00; One party hat (🥳): 13:00. All other solvers earn a 🦕: Thankful Tazoudasaurus.

Author/Opus: This is the 130th puzzle from Bill Murphy, 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). The clues outside the grid reveal the first odd or even value appearing in that direction in the row or column. Any number of values of the opposite parity (even or odd) may appear before the first odd or even number.

XY-Differences Sudoku by clover!

For the second time in about a month we have a “Diamond Ring” puzzle from clover!; we expect this variation may lead to a sharper puzzle.

Theme: Diamond Ring II

Author/Opus: This is the 151st 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). If a diamond is given between two horizontally adjacent cells, then the two numbers in those cells must differ by X, where X is the first number in that row. If a diamond is given between two vertically adjacent cells, then the two numbers in those cells must differ by Y, where Y is the first number in that column. Pairs of cells without diamonds can have any relationship. For instance, the difference between R7C3 and R7C4 is equal to the value in R7C1 (= 1).

Author/Opus: This is the 129th puzzle from Bill Murphy, 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). 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. At least one of the numbers along the path in each arrow must be repeated. (E.g., 1 + 1 + 7 = 9 would be a valid sum but 2 + 3 + 4 = 9 would not, as no number repeats.)
