Author/Opus: This is the 71st 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 XIII or VIII, reflecting the numbers 13 or 8 in Roman numerals, is placed on the edge between cells, the numbers in the two adjacent cells must sum to exactly 13 or 8.

More seriously: Today’s GAS combines the puzzle style Skyscrapers with Sudoku, forcing you to think of each number’s height when making your placements. Less seriously: Did you also look at the theme and wonder “6 7 8?” Kind of an adult version of “6 7?” You’ll have to think to get these three numbers in the grid.

Author/Opus: This is the 70th 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, as in the puzzle Skyscrapers, each number in the grid represents the height of a building and the clues on the outside of the grid indicate how many buildings can be “seen” when looking from that direction. Taller buildings block the view of smaller buildings. For example, if a row contained the numbers 198432675, then two buildings are seen from the left – 1 and 9 – and four buildings from the right – 5, 7, 8 and 9 – with the other buildings blocked by taller buildings in front of them.

The sum constraint insanity continues. When, across these Serbian Frames and XxVx Pairs puzzles, can we agree to just put the normal representation of sum values directly on the edges of the added cells? Maybe those comments to simplify Sudoku variations are for another day; enjoy thinking about all the VII and XII values today!

What some may have seen as a typo of a 6 for a 5 in an earlier XV Pairs Sudoku by clover! may have merely been a new “portal of discovery”. Here we have XIs and VIs and the logic still has a certain kind of rhyme.

In this Sudoku variation, some special “slingshot” cells show how far one number above/below the cell is slung to the left/right in the next row. Can you follow all the leaps of logic?

Author/Opus: This is the 65th 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 4 is in R2C2 (the slingshot cell), and if the value in R1C2 pointed at by the circle is 3, then there would be another 3 four steps to the right of the slingshot in R2C6.)
