"Broken" Kropki XV Sudoku Tic Tac Toe

(Published on 4. January 2021, 00:38 by Ryx)

This puzzle was my submission for this month's Discord puzzle theme: "broken"


"Broken" Kropki/XV Tic Tac Toe Sudoku
  1. Normal Sudoku Rules apply
  2. All Kropki and XV clues are made up from only digits within the same box. These clues are forbidden from appearing on a box boundary.
  3. In all but box 5, all black Kropki dots, separating digits with a ratio 1:2, are given (negative constraint applies). No white Kropki dots are used in this puzzle.
  4. In all but box 5, all XV clues, where the adjoined digits add to 10 or 5 respectively, are given (negative constraint applies).
This Sudoku puzzle is also a game of Tic Tac Toe. Normal Tic Tac Toe rules apply, with the following exception: "X" and "O" do not take turns, they win a box by dominance of XV or Kropki clues within each box. If there are more XV clues than Kropki clues in a box, the box goes to "X". If there are more Kropki clues than XV clues in a box, then the box goes to "O".

So, as you can see, the game currently in play is in a deadlock, with "X" having won all four corner boxes and "O" having won boxes 2, 4, 6 and 8.

So, to comlete the Tic Tac Toe game and find a winner, you must complete the puzzle and determine the winner of the center box. Though, I fear this puzzle may be broken and there might not be a winner.

Loved the puzzle but I did not like the way it ended, as I thought the last disambiguation should give XV the edge over the dots.

Ryx: Well, glad you loved the puzzle. And I agree, I always think X 'should' win

Zum Glück ging es auch ohne Tic Tac Toe gut durch ;-).

Very pleasant, easy puzzle! Well done :)

@rachelushy Thanks for the feedback. I am just testing out my next one. Same theme (Tic Tac Toe-duko) ... might be a tad more challenging than this one. But, If I can solve it, most everyone can ;-)
