Triangle Inequality
(Eingestellt am 7. Dezember 2025, 08:00 Uhr von Kaktuslav)
Rules: Normal sudoku rules apply.
Triangles: Three digits connected by a triangle represent the side lengths of a valid triangle (i.e., the sum of any two sides is greater than the third). No two triangles in the grid have the same sum of their three digits. Every blue triangle has a greater sum than every orange triangle.
Lösungscode: Row 5

Very nice construction! Easy with the blue triangles when you get the implications, but very resisting with the yellow ones. Absolutely amazing how it all comes together, let alone how to come up with such an idea.

Loved it! Very tough and required me several visits, but it slowly showed itself with very elegant steps

Fantastic! Hard, but absolutely fantastic, and the rather low rating doesn’t do justice to this little gem!

Missed opportunity to say no two triangles have the same perimeter XD. Splendid & amazing puzzle despite me doing too much arithmetic at the start before seeing the geometry of the triangle.

Once again, Santa dropped a box too early under our trees. This is more than an advent treet. What a big forgiving heart Santa has, also passing through troll villages.

This is normally a bit above my difficulty level but I made my way through in the end and I'm glad I did! Spectacular puzzle with some really cool and original logic.

Very fun with plenty of moments that made me feel very big-brained. Helpful to have solved with pen and paper handy; curious how I would've fared without that.
