When it comes to safely packing numbers into a grid, some might consider the 28th and 29th constraints (the diagonal bands) last since they seem “extra”. How will your filling of this Diagonal Sudoku go?

Theme: Don’t Get Mad, Get Even Sandwich

Author/Opus: This is the 99th 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 clues outside the grid indicate all numbers in that row or column surrounded by even numbers on both sides (“sandwiched”). Clues can be given in any order, and all such numbers are given. If no clue is given, there may be any count of values (including no values) sandwiched between even numbers in that row or column.

This quirky combo is new to GAS, though its components aren’t: clues outside the grid are both X-Sums and Sandwich clues!

Author/Opus: This is the 80th puzzle from Philip Newman, 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 indicate the sum of the first X numbers placed in the corresponding direction, where X is equal to the first number placed in that direction (e.g., if R9C3 is 4, then the four numbers in R9C3 (i.e., 4), R8C3, R7C3, and R6C3 all add up to 10). Clues outside the grid also give the sum of numbers in the cells between the 1 and the 9 in that row or column.

Today’s GAS involves a bit of neighborly addition: Each outside clue shows the sum of the numbers (one or two) around the nine in the row or column.

Theme: Sums Are My Favorite Things

Author/Opus: This is the 98th 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). Clues outside the grid indicate the sum of the number(s) immediately adjacent to the 9 in that row or column. For instance, R8C7 and R8C9 sum to 6. If there is only one number next to 9, the outside clue gives the value of that number.

If you haven’t tried a 159 (or other Column Indexer) before, you might check out the previous GAS featuring this variant. Today’s offering adds Arrows to the mix!

Author/Opus: This is the 79th puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS) team.

Rules: Standard Arrow 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. Numbers can repeat within an arrow shape.

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 second row there is a 2 in column 1 in the red column indexer, then the 1 in that row is in column 2; similarly, if there is a 5 in column 7 of the bottom row, that would mean column 5 of the bottom row contains a 7 because of where the 5 would be indexed.)
