Differences Count
(Published on 14. November 2024, 10:29 by marty_sears)
Rules: Normal sudoku rules apply. Digits separated by a black dot are in a 1:2 ratio. The difference between two adjacent digits on a coloured line indicates exactly how many pairs of adjacent digits along that line have that exact difference.

Wow what a fun ruleset. I found 1 & 2 to be very quick and easy, but 3 to be MUCH harder. Didn't feel like i could break in at all, then finally found a crack and chipped away and it all came down pretty naturally after that.
My jaw dropped when the top kropki was solved. Very cool :)

I had already done sujoyku's lovely 6x6 series Neverending Story on these lines, but only realized when CtC featured this I hadn't solved the original set! Having that experience under my belt probably made this easier than it would have been otherwise, but still love it all!

Good and interesting line type. Great puzzles!

I like the new concept with States that you need to solve it in parts.
As well as the new constraint.
Nice flow, at some point i overlooked a thing and needed to backtrack. But other than that it flowed nicely.

A wonderful experience. I really liked the way the new line is introduced along puzzles. Even the final grid had a great solving pace filled with great moments

Thank you for this nice puzzle, dear marty_sears and sujoyku! :) It was hard for me to get used to the new rules, but then I really enjoyed it! :)

Excellent new rule set and introductory path, as others have commented. It's interesting that in some ways the shorter lines are more powerful than the longer ones. Thank you both for the puzzles.

Awesome! Took me a little to spot the break in to part three but it was very smooth from there

Very good introduction to a line type I hope to see again and the kind of logic it can lead to.

Very satisfying. These lines are more straightforward to me than some other counting rulesets while creating some very neat interactions! Thanks :)

As others already mentioned this is a perfect introduction of a very interesting idea. Thank you very much for creating and sharing.

That was a beautiful solve that flowed from start to finish. Great new variant idea and superbly constructed. Thank you both.

Simply amazing! I have to admit I had more problems with the 2nd grid than with the 3rd lol

Loved this. I broke it a number of times before I prevailed, but it was an extremely enjoyable tussle. Lovely rule set, and I did appreciate the inclusion of smaller introductory puzzles. Thanks very much to both of you.

Congratulations for the birth of this new line. You both must feel very proud. Did you ever decide on the name of this baby line ? CD line maybe ? Let us know.

Thank you for this wonderful collaboration, Marty! It is incredible with what ideas you came up for the new Counting Differences ruleset. I hope there will be many more occasions for us to work together!

Great invention. Great set of introductory puzzles. Felt lucky to find a quick break in to the final one. Very smooth. Great fun thx you both.

Thank you so much for the 3 parts that allowed me to gradually discover the key aspects of these lines before applying them in the challenging final puzzle! I really enjoyed that.

Very cool lines! This puzzle sequence is also a great way of teaching the rule

Enjoyed this a lot. Certainly takes a bit to understand the secrets of these lines. Nice presentation with the puzzles linking to one another!

Very interesting and simple new line type!
