Author/Opus: This is the 137th 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 cells are marked with gray lines pointing out from their centers; in the directions of those lines, the numbers entered N cells away must be identical where N is the value in the cell with the lines. Not all possible gray lines are given. (For example, since R1C4 = 2 with lines going left and down, R1C2 and R3C4 must contain the same number.)

This Emitters Sudoku by Bill Murphy has cells with a “don’t go over the value” sum constraint, leading to some interesting deductions to find.

Author/Opus: This is the 134th 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 circled numbers are “emitters.” In each orthogonal direction from an emitter, a line is drawn as far as possible to show the largest set of values that can be added together without exceeding the value of the emitter. (E.g., below R5C3 is a two-cell line so R6C3 + R7C3 ≤ R5C3 and R6C3 + R7C3 + R8C3 > R5C3.)

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.)

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.

While an Arrow Sudoku may have some numbers repeating on the arrow paths, in this variation there absolutely must be a repeat.

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.)

Author/Opus: This is the 128th 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). Each value greater than 1 that is in an orthogonally connected, decreasing, consecutive path that ends in 1 is shaded gray. (E.g., 4-3-2-1 would make a valid path, but 6-5-3-2-1 would not, as 5 and 3 are not consecutive.) Paths may overlap each other. All 1s must be in white cells and all possible shaded cells are given.
