Author/Opus: This is the 164th 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). Additionally, wherever two numbers are given outside the grid, they must appear in either order in the first and last three cells in that row in symmetric locations relative to the center. For example, if one of them appeared in column 2, the other must appear in column 8.

Theme: Semiramide

Author/Opus: This is the 183rd 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 7 means R7C1 > R7C2 > R7C3. (The absence of an outside arrow clue has no meaning in this puzzle unlike “standard” Rossini Sudoku.)

Theme: 159159

Author/Opus: This is the 182nd 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). Also, the cells marked in red are column indexers. In this puzzle, 1, 5, and 9 are the column indexers. If the number X is in a red cell in column Y in a given row, then in the same row the number Y is in column X. (For example, if in the third row there is a 3 in column 1 in the red column indexer, then the 1 in that row is in column 3; similarly, if there is a 5 in column 4 of the third row, that would mean column 5 of the third row contains a 4 because of where the 5 would be indexed.)
