This the second time we’ve posted this variant (this link will help detect its twin). Can you make all the sums work out as marked?

PDF

Author/Opus: This is the 95th 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 R3C7 has a left arrow, either R3C6, R3C6 + R3C5, or R3C6 + R3C5 + R3C4 must sum to the value in R3C7 = 8.)

Bill has one more Zipper Lines puzzle to add into the conversation; can you find your way to the one solution?

PDF

Author/Opus: This is the 93rd 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). For each line, the numbers in each pair of cells an equal distance away from the center of the line must sum up to the value in the central cell of the line. (In this puzzle, the lines that cross go straight through those cells; this means, for example, R3C1 + R3C3 = R3C2 from the Zipper Lines rule.)
