Autoglyphs 4 (ESL)
(Published on 28. July 2025, 05:28 by juddimal)
A new series with digits made from lines, now introducing another limit on what digits can appear on a glyph. Autoglyphs roll out!
Normal sudoku rules apply.
EQUAL SPLIT LINES: Dots split lines into segments with equal sums.
KROPKI: Digits in cells joined by a black dot are in a 1:2 ratio.
AUTOGLYPH: Lines create shapes in the form of a digit. That digit must appear exactly once on the line.
ANTI-ROMAN: If an autoglyph represents the digit X, then 5-X ,10-X, and 15-X may not appear on the same line. The glyph 5 must have a 5 and has no negative constraint.

Here is a ""look-and-say" cage example of how the new rule works. The line in box 7 can be interpreted as a 2; that line must contain the digit 2, no digit 3 (sums to 5), and no digit 8 (sums to 10).
Solution code: Column 1 (9 digits)

It was very difficult for me. I’d be curious to see how someone smarter than me does it.

Additional rule for the digit 5.

Yes, 5 must have a 5 on it, but no negative restriction.

That‘s an elegant ruleset combined with a nice layout and a quite approachable solution (2* for me). Thanks for sharing.

Very nice puzzle, for me 3* but then I did use a cage calculator to help. The anti-roman rule gave me pause since it seems to contradict itself on the 5-glyph but I made the reasonable assumption it didn't apply to itself.

for ambiguity reasons might need to add that ANTI-ROMAN does not apply to the 5 glyph
