The Victoria Sandwich Is A Lie

(Eingestellt am 8. Juni 2022, 17:50 Uhr von fjam)

Das Enrichment Center gibt Ihnen folgenden Hinweis: Sie werden gebacken und dann gibt es Kuchen.
  • Normal Sudoku rules apply.
  • Clues outside the grid give the sum of digits sandwiched between a 1 and 9, starting from the first 1 or 9 in the respective row/column. However, these clues are lying and must be increased by X, where X is the digit nearest to the clue in the respective row/column.
  • The oval shapes are portals. Each portal has a partner, such that there are four pairs of portals which must be deduced. Pairs of portals contain identical digits.
  • When a row/column sandwich sum hits a portal, it travels through it and continues towards the 1 or 9 in the new row/column.
  • Digits in portals do not count towards sandwich sums and cannot be 1 or 9.
To help solvers visualize the rules, an example image is provided. This may be solved as a bonus classic Sudoku.

Sum continues travelling right towards 9 (started with 1).


Sum U-turns and travels right towards 9 (started with 1).


Sum starts after portal, so portal is ignored.


Sum includes extra 1 as it ends at the 9.

As an extra clarification note for solvers, do not think of portals as having directional properties in this puzzle. For example, while a column sandwich continues as a column sandwich after a portal, whether it travels up or down is determined only by where the closing sandwich 'crust' digit is. As such, it is possible for two sandwich sums, one starting from 1 and one from 9, to enter the same portal from opposite directions, but then travel in the same direction on exiting if the 1 and 9 in the new row/column are on the same side of the destination portal.

The idea for a puzzle themed around the game Portal had been in mind for a while, but Playmaker6174's Portal Sum - Little Killer gave extra impetus to put this together. The webpage for that puzzle can be found here.

Very impressive setting for this puzzle, but insane solve. Always remember to add the digits to those clues, because that kept tripping me up!

Absolutely brutal and insane, one needs to stay awake mostly all the time to keep track with what's going on, and I slowly but surely turned into a completely terrible solver and an angry person as well in the later half. Nevertheless, I'm glad that the portal idea inspired you to make such a wonderful puzzle :)

I did it!. That was exquisite and also pretty darn hard :) I was sure I had broken it, but I was still convinced that my logic was sound, and I made it through eventually. Lovely stuff
