Dotted Region Sum Lines / Gepunktete Region-Summen-Linien
(Published on 16. October 2022, 17:08 by PDN777)
Normal sudoku rules apply. The digits along a blue region sum line must have the same sum in each 3x3 box entered by the line. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

Thanks for the puzzle. It has a nice consistent level of difficulty throughout.

I did it! Really struggled, cause (spoiler) thought that sequence of four cages connected by black dot gotta be 1248 in some order. Then it struck me and everything was fine and dandy afterwards
** Yes, those black dots make a turn! :-) Thanks for the solve.

Thanks everyone for the solves and comments! Region sum lines seem to be getting more and more popular, so I hope this easier puzzle was a good introduction. Have a super day! :-)

My first region sum lines puzzle, too. Took me two attempts as well, but had a great time. Thanks a lot!

I really liked it. Also did a mistake, so i had to restart. But 2nd try was a smooth solve. Thank you!

Fun to solve. Took me around 55 minutes. Not that hard but on the other hand no so easy for me. Maybe my thinking was a bit slow.

Despite 2 dumb mistakes being made by me early on, it was a smooth solve path. Very nice puzzle!

After two failed attempts (don't really know what I did wrong) I managed to solve it. As always, big fan of your puzzles. Not too hard, not too difficult.
Thanks.

Nice puzzle - it was my first region sum lines, flowed very nicely.

I think the puzzle is less than a two star puzzle if you know region sum lines and kropki dots well. I really enjoyed the flow of the puzzle.
** Thanks for the solve, and it's clear you were correct about the difficulty. :-)

Really fun to watch all the pieces fall into place on this puzzle. If you've done region sum lines before this one should be a cakewalk.
** Glad you enjoyed, and yes, it seems this was easier than I thought. :-)
