Author/Opus: This is the 185th 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).

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.)

Will your puzzle solving find its target or miss the mark in this Slingshot Sudoku?

PDF

or solve online (using SudokuPad)

Theme: Short Shot

Author/Opus: This is the 176th 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, there are some “slingshot” cells marked in the grid with a circle and arrow. The circle indicates an adjacent cell whose value will be slingshot in the direction of the arrow. The number in the slingshot cell indicates how many cells away that circled cell’s value lands in the arrow’s direction. (For example, if a 3 is in R1C4 (the slingshot cell), and if the value in R2C4 pointed at by the circle is 5, then there would be another 5 three steps to the left of the slingshot in R1C1.)

If you solve in SudokuPad, the blunt end of an arrow will serve the same function as a circle shown here.
