Sudoku Binary puzzle!

Question

Posted (edited) · Report post

While I was relaxing on the sunny shores, a messenger brought me a letter from an eyeball giant who is apparently stuck on a sudoku puzzle. Since she has no eyestalks, she invariably sucks at math, being forced to use a binary system for calculus.
Here is the puzzle in question, a great eyeball giant with as many as 16 eyes!

5A 3 26 D

1 7 B 5E

7B 63FC A

40 1 8
5 3F 8 2 0C
3 87D A
8 C7 6 F 50
4 D 5A B3 C E

OK I've worked on this for a while.

Convinced it has no solution.

BTW it's Hex, not binary.

Bonanova, as you say you believe it has no solution, I infer that you believe you know what the problem is! All I can tell is that there's a 16x16 grid (Thanks to your reformatting!). Perhaps it could be viewed as a 4x4 grid of 4x4 cells (without lines). I can't tell how it relates to Sudoku, which I think of as a 9x9 grid. What is your interpretation of the problem? At least I can learn from that :-)

Of course, we could see each hex digit as a 2x2 bit matrix, but I don't see that that helps, either...

The objective of this puzzle is to solve this hexadecimal sudoku. Instead of 1-9 digits in 9x9 grid it uses 0-F digits in 16x16 grid.

Good to know it can be solved. I'll keep working to solve it myself. :thumbsup:

I'm wondering if the solution is unique. It will be interesting to see if another solution presents itself.
