Dude! Where's My Givens?

(Published on 10. August 2021, 18:13 by RockyRoer)

In this fun sudoku variation - the 'given digits' have been hidden. The solver must determine their locations. Note, don't skip the example puzzle! It's a very fun little puzzle that will likely teach you some logic that will be helpful in the 8x8. Also, if someone wants to create a full 9x9 - please do! My summer vacation has run out and so I won't have time to get to it. I'd love to see what someone else could make with this idea!

The Rules:

  1. Normal sudoku rules apply.
  2. Given PairsThe ordered pairs in the grid indicate where the given digits are. The ordered pair in box 1 indicates the row and column where a 1 occurs. The ordered pair in box 2 indicate where a 2 occurs, and so on...
  3. Variants: (not all X/V/kropki possibilities are given)
    • A white dot separates cells that are 1 apart.
    • A black dot indicates cells with a 2:1 ratio.
    • An X separates cells that sum to 10
    • A V separates cells that add to 5.
    • A less than / greater than symbol points to the smaller cell

An Example:

The ordered (5, 2) in box 1 means that there must be a 1 in the Row5 Column 2. (note: this may not be the actual digits in those cells if you try the puzzle!)

The Puzzle: (8x8) https://f-puzzles.com/?id=yfkfmjrc

Solution code: The location of all 8 givens, in order. That is, the ordered pair in box 1, then box 2 box 3... (16 digits) (The solution code for the example puzzle would be 3241366412)

What a wonderful ruleset. I haven't found it particularly hard so far - almost solved it (famous last words) - but I can see how it could be very challenging on a proper 9x9 grid with even more devious logic built in. Looking forward to seeing what the community does with this rule set.

I did have to break out a piece of paper to keep track of stuff in a chart, but the logic was very smooth and enjoyable.

Cool concept! :-)

Sweat equity. Nice puzzle, albeit not for the faint of spirit!

How about a 9x9 grid with no given digits, no extra rules, only kropki dots, Xs, Vs, or inequality signs between the elements of the ordered pairs? That should be hard to construct.

Very nice!

Added solution to 6x6 example, and German translation, via Google Translate. Let me know if anything seems amiss. I'm especially unsure about how the mathematical term 'ordered pair' gets translated into German.
