Title: XV X VX
Type: Sudoku
Link: F-puzzles link to XV X VX Sudoku
Variants: XV, Modified VX, X
1) Normal Sudoku
- Place the digits 1 through 9 once each in every row, column, and box.
- 2.1) An X either sums or multiplies two adjacent cells (being simultaneously a sum and a multiplication is permitted).
- a) When X acts as a sum, the two cells sum to 10.
- b) When X acts as a multiplication sign, the two cells are multiplied together with their product immediately following to the right for rows or downward for columns.
- i) All sums of 10 are given. Negative constraints apply.
- ii) All multiplications are given. Negative constraints apply.
- 2.2) A V either sums or represents an inequality between two adjacent cells (being simultaneously a sum and an inequality is permitted).
- a) When V acts as a sum, the two cells sum to 5.
- b) When V acts as an inequality, the one cell is greater than the other in the direction of the V.
- i) All sums of 5 are given. Negative constraints apply.
- ii) Not all inequalities are given.
3) X Sudoku
- Digits along each diagonal must contain all of the digits 1 through 9 and must not repeat.
Solution code: Please enter the nine digits of column 5 from top to bottom then the nine digits of Row 8 from left to right. No spaces between

Cool concept! Quite a mental workout to keep up with everything, especially considering the negative constraints that apply here. It was rewarding to get through it though.
The rules here and on f-puzzles differ slightly: here it states that all multiplications are given, while the rules in f-puzzles state the opposite. You might want to fix that. Also, for clarity, it might be helpful to add ', or both' to the first sentences of 2.1 and 2.2 (e.g. 'An X either sums or multiplies two adjacent cells, or both'). When I started the puzzle I wasn't sure whether this meant it could or could not be both, but looking at the solution it can be both.

Great suggestions that I will incorporate. The rest of the series is slightly different in that I change the digits to 0 through 8 to create even more possibilities and mental exercise. Thank you for solving my puzzle. ~ZH
