Japanese Sum Cave Cipher #10: Caesar Cipher (shift ±1)

(Eingestellt am 29. Dezember 2022, 18:27 Uhr von KNT)


I was feeling very inspired to try my hand at this ruleset after solving this absolutely magnificent puzzle, which I wholeheartedly recommend to anyone looking for a challenge.


Place the digits 1 to 9 once in each row and column of the grid, and shade some cells so that the unshaded cells form a cave.

Outside clues are Japanese sum clues. Clues to the left of the grid are Japanese sum clues for either shaded or unshaded groups of cells, where each group needs at least one of the other (shaded or unshaded) to separate the groups. Clues to the top of the grid are Japanese sum clues for the OTHER of shaded or unshaded. (That is, if it turns out clues to the left indicate sums of unshaded blocks, clues to the top indicate sums of shaded blocks).


The cipher for the clues is incorrect. Each letter from A-J is still assigned a unique value from 0-9, but each letter provided must be swapped with an adjacent letter alphabetically. Example: A given F is either E or G. A given HB is either GA, GC, IA, or IC.


Below is an example and its solution with the digits 1-7 (and a cipher where A-H replaces 0-7). The left image shows the given clues, the right image shows the correct clues. It can be solved here.

The main puzzle can be solved here. Enjoy!

Yet another amazing puzzle! It's incredible how the puzzle can be so complex, yet so smooth after all the key deductions are found.

I am running out of superlatives for your puzzles. But this is one of my favourites (again).

Loved it, and it wasn't too hard.

I really liked the logic, but it was very hard for me to discover even the easy steps - so basically almost every step in this puzzle :o)) - luckily got there in the end. really well set. my favourite part was how the J clue was determined.

So much fun! Very mathy, which I find difficult at times, but there is a staggering level of clarity and some nice tricks in there :)
