Broken Clock

(Published on 22. November 2025, 11:15 by Wiggel)

I wanted to make a sudoku with as many different Roman numerals as possible.
To make it easier to parse, even for people not that fluent with Roman numerals, I used a clock as the base.
The result is a fairly approachable puzzle. Enjoy.

Solve on SudokuPad

Rules:

    Normal sudoku rules apply.
    Roman numerals: Digits touching a Roman numeral sum to its value.
    Kropki dots: Digits separated by a white dot are consecutive. Not all dots are given.

Solution code: Row 1 (left to right)

Nice one, but making the clock a lighter shade would help with pencil marks.

It would've helped if i hadn't kept trying to make 1-9 add up to XI. ;)

Took me a moment to clock what was going on but after that everything was smooth so unlike this device I didn't lose an hour.
