Theme: Go West

Author/Opus: This is the 85th 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, numbers along each line must have values strictly between the values of the two numbers in the circle cells bounding that particular line. (For example, R3C2, R3C3 and R4C2 must have values strictly between 1 and 4, the values in R4C1 and R2C3.)

Theme: A Long Time Coming

Author/Opus: This is the 106th 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). Clues outside the grid indicate the sum of numbers in that direction starting at the first cell in the row/column and continuing to either the first odd number or the first even number in that direction. The solver must determine if a clue refers to an even or odd number as the stopping point. (For example, possibilities for the left of row 2 include 643 as 6+4+3 = 13 and 3 is the first odd number, or 76 as 7+6 = 13 and 6 is the first even number. A one-digit outside clue could reference just the first cell, since that would be the first odd/even number in that direction.)

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

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

Author/Opus: This is the 82nd 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). Arrows in the grid indicate that there is a run of cells in the given direction that sums to the number in the cell containing the arrow, starting from the first cell seen by the arrow. Not all arrows are given. (E.g., because R4C2 has an up arrow, either R3C2, R3C2 + R2C2, or R3C2 + R2C2 + R1C2 must sum to the value in R4C2 = 4.)
