Epiphany (Numbered Room and Region Sum Line)

(Eingestellt am 30. September 2022, 10:32 Uhr von Playmaker6174)

The following puzzle uses one of those combos that didn't really give me much impression or ideas at first but after careful analysis it's actually worth the effort and can be done elegantly, and that is Numbered Room + Region Sum (Equal Sum) line.

Though the flow in this puzzle is quite unusual from my perspective, the break-in and the interactions are... well, interesting and funny to see; I'd also say that this puzzle is somewhat a fascinating discovery to myself. Estimated difficulty is around 4/5 (and may be lower), I hope you enjoy!

Rules:

- Normal Sudoku rules apply for the 9x9 grid: every row, column and 3x3 box contains digits from 1 to 9 each once.

- A clue outside the grid indicates the digit that has to be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell. For example if R2C1 is a 4 then R2C4 has to be 9.

- For each blue line in the grid, digits on the line have an equal sum N within each box it passes through.

Good luck and have fun solving!

I had toyed with the idea of this combination for a while but wasn't sure i could get it to work. Now you've put a high bar out there!

Thank you everyone for the great feedback, glad everyone enjoyed it! I didn’t have so much expectation to get this combo work properly enough but after few days, when I revised some of the numbered room puzzles in the past (Angelo’s [id=000AA7] and Qodec’s [id=0009Q4] ), I finally got an idea for the main opening and then the rest of the puzzle :)
