Position Sums Fillomino #2
(Eingestellt am 23. Oktober 2022, 05:47 Uhr von ONeill)
For reference, this grid is 13x13 with the central 5x5 missing. This one is less approachable than the first but no single step is too difficult. I hope you enjoy!
Rules:
1. Divide the grid into regions so that no two regions of the same size share an edge. Enter a number into each cell equal to the size of its region.
2. Let A and B be the digits in the first and second cells of the grid from any direction
a) Unshaded clues outside the grid indicate the sum of A and B
b) Shaded clues indicate the sum of the digits in positions A and B from that direction. Note that it is possible that A and B index the same cell. If A and B index the same cell, the sum is twice the value of the cell they index.
3. If a clue is circled, the cells that are part of its sum belong to the same region. If a clue is not circled, the cells that are part of its sum belong to different regions.
4. A question mark can stand for any positive integer (including 2-digit numbers).
Note: Although this grid has cells missing, indexing works as usual. That is, if r5c1 is indexing r5c13, its value is 13. For any shaded Ath+Bth clue, A and B cannot index a cell that would be in the central 5x5 area or fall outside the grid. Eg. 5 and 14 are not allowed in r7c1, but they are allowed in r13c5.
The puzzle:
Answer check is enabled with digits or green edges.
Lösungscode: Column 1

We were so close to discovering the secrets of the universe... We fell off one short...

Very nice puzzle! It's always very satisfying to work out these seemingly impossible regions :-)

really great once again, felt easier than then the previous one, but perhaps I'm just getting used to this ruleset

Wonderful puzzle ! Starting to see a pattern emerge in your setting style, which is auguring very good things for your future work (and our future solves !). Thanks++

Awesome puzzle, definitely my favourite of your puzzles so far! Some really great region geometry logic in this one, and there were indeed some compass fillomino-alike moments :). Challenging and very enjoyable!

Fixed clue and removed redundant clue.

Really cool puzzle! I think it is a big step up in difficulty from the first one, but with some great logic.
One remark: I am pretty sure the 22 clue on the right side should be circled, correct?
- Thanks a lot! You are most definitely correct, I will get that changed now.

If I wanted to index the cell in the last column in R5 for example, would this value be 8 (excluding central 5 cells), or 13?

It would be 13. I will clarify that in the rules, sorry!
