Loop With A Difference
(Published on 5. May 2023, 00:09 by Scruffamudda)
Normal sudoku rules apply.
The solver must draw a single loop which travels along the grid lines but not on the outer perimeter. The loop must not branch or touch itself.
A digit in a blue cell shows the number of that cell's corners (grey dots) which touch the loop.
Pairs of digits separated by the loop have a difference of 1.

Such a beautiful puzzle! Tough, but there's a logical solve path throughout, and I never got stuck for too long.

Brilliant idea. I couldn‘t believe that the high digits would solve uniquely, but they did. Thanks

Absolutely a joy to solve. It was a bit harder for me than a 3, but I was solving at 1 AM, while tired.
The loop and difference rule was very interesting. I found myself constantly wondering how is this going to solve. And then I spottet a bit of logic that progressed the solve. And that just kept repeating

Just solved the 6x6 and it brought me back to my slitherlink days! I'll save the main puzzle for later. I was never good at the corner-counting variant of slitherlink though, so we'll see how I go!
