Suguru Chaos Deconstruction #5: Region Sums

(Published on 23. March 2022, 01:51 by mathpesto)

This puzzle is the fifth in a series, and I think it's the most challenging, so I'd recommend trying out some of the others first (#1, #2, #3, and #4.) Much gratitude to @henrypijames who suggested I try a region sums puzzle in this series. I probably wouldn't have thought to do it myself! And shoutout to @henrypijames and @ClashCode for testing the puzzle! If you get stuck, feel free to post a hidden comment, or find me on Discord and I'm happy to help out. Hope you enjoy!


Rules:

Fill some cells in the grid with the digits 1–9 such that no digit repeats in a row or column. Cells with a line or square must have a digit in them. Cells with a gray square contain an even digit.

Deconstructed Suguru: All digits must belong to a region, which is a collection of orthogonally connected cells. A region of size n contains the digits 1 through n once each. Regions may not touch each other orthogonally, although they may touch each other diagonally.

Region Sums: Digits on a line must have the same sum in each region the line is in. Each line is in at least two regions. (Note: If a line passes through a region multiple times, each individual segment sums separately.)

It's so easy to make stupid mistakes when scanning rows and columns on big grids like this - I finally made my way through, but I had to go back and correct something in a region when I realized I was lacking a digit - fortunately that particular bit wasn't costly, and didn't impact the main solve path

Lovely --- took me almost two hours to solve :)

Wow! The most difficult in the series. But so fun.

Exactly 200 minutes on this one. Brutal but beautiful.

I'm glad this is the most challenging so that when I try 1-4 I should hopefully have a slightly easier ride. Still, this was very clever and rewarding.

I almost wanted to give up after having done three quarters.Then suddenly I found a restriction that led right to the final solution. What a crime story. Fantastic creation!

Took me three attempts and probably over 5 hours but I got it. Definitely one of the harder ones in the series. Great work!

Here ends at first my journey through your adventurous deconstructed suguru puzzles.

It was easy to make wrong deductions and that you miss very helpful clues. In the early mid I discovered something which was beautiful and massive supportive.

Ty again 4 sharing your work with us.

I abandoned the puzzle twice, after having filled more than half the grid each time. On the third attempt, i was more dogged and though it took more than 6 hours,i got thru, on sheer doggedness, I suppose. The puzzle is 6 out of 5 stars on difficulty scale ! But, to be honest, barring some rare aha moments, it mostly felt like a chore - each deduction was very very hard to come by! I have solved 2 chaos construction puzzles earlier but this was brutal !! Feels good at the end though. Thanks, @ mathpesto :)

Those who cannot do, talk. Talk is cheap, but in this case, I was able to talk (pester, really) @mathpesto into creating this great puzzle, which I definitely consider a highlight of this entirely fantastic series.

lol I'm glad you "pestered" me because it was a lot of fun to make!
