Picnic Sudoku - Irregular Blankets
(Eingestellt am 23. Juli 2021, 20:09 Uhr von hamslice)
Standard Sudoku rules apply except the regions are irregular in shape and are to be deduced.
Digits on thermometers must increase from the bulb end to the tip. If a thermometer leaves a region, it may not re-enter that same region further along the thermometer.
Clues outside the grid indicate the sum of the digits between the 1 and 9 in the respective row or column. Digits between the 1 and 9 in any row or column (never including the 1 or 9 themselves) is classed as a sandwiched cell.
For each thermometer, every cell on the thermometer must be a sandwiched cell OR every cell on the thermometer must belong to the same region. Conversely, if a thermometer is entirely enclosed by a single region, then no cell on that thermometer may be a sandwiched cell.
Penpa+ Link I had fun making this picnic, and you know what they say about picnics: don’t forget your leftovers, it’s a law!
Lösungscode: Row 1, then Column 9, then the number of regions touching the edge of the grid, in a 19-digit string.

I can't check the link, but I think you got the sandwich right. I've been through the same scenario. The 19 on the top right can branch or go down.

After 5+ hours I thought I got it, but the last regions don't fit. Can anyone please tell me if I at least got the sandwiches correct?

A whole morning gone. I was like, wake up puzzle. I'm going to find a sandwich.
Hints for future solver, 19 can be on the thermo and not sandwich, a row sandwich can also be at a non column sandwich part. Or you'll break it.

Ooo, I get it, that's hard.

Just to be clear, thermo can only be all sandwich or one region? No partial sandwich allowed?

Yep, no thermometer can be partially sandwiched. :)
