That is a bug that I will fix as soon as possible. Sorry!

...the ability to switch to a lighter design, and the game will reveal region borders when a new grid is discovered. (Note that the solution for one secret room has changed in a way that should be apparent.)

Great news, I have worked with SudokuPad's Sven to create custom ids for the Sudokuvania puzzles. For example, you can play Lineage of Logic at sudokupad.app/sudokuvania/.... Sudokuvania 2 is now updated to version 1.1, which includes...

Interesting theory! No, they can't point past the edge of the grid, which is why the copycat cells are so important to breaking in.

No, the negative constraint doesn't extend to this boss.

No, the grids still use the digits 1-9, but cells having values other than the digit means they interact with clues differently. Most clues care about the value of the cells they enter, not the digit.

The good news is version 1.0.2 of Lineage of Logic is already available! sudokupad.app/0dw3geb3vv?s... The bad news is it was needed to fix a boss puzzle that v1.0.1 broke. To make things worse, DO NOT play the Observatory boss puzzle from 1.0.1 (short id zs7fha4s95) or you will LOSE all progress!

Version 1.0.1 of Sudokuvania 2 is available here: sudokupad.app/jks1ipzelj?s... It addresses several points of confusion, changes away from icons not appearing to people using Linux, and corrects errors in two of the later boss puzzles. Full patch notes are on the Sudokuvania website.

Every enemy can be skipped with logic. And yes, it is possible to get the bad ending without anything from the shop. Try a minimalist playthrough next time!

Skeptical Mario @skepticalmario.bsky.social · 29/07/2026
I am planning on adding clarification around this. To get the clues from the shop, you need items given by the optional bosses in the Kitchens and Sewers.

Dark Inversion follows different rules: first you get the digit for the boss in the main map, and then the corresponding cell in the UI section is unfogged and you get the link there.

Correct, there are intentionally multiple ways to proceed and optional clues. This flexibility will make Lineage of Logic easier and more replayable than its predecessor.

Only one week until everyone can play Sudokuvania 2: Lineage of Logic! In Sv2, there are not only challenging boss puzzles (😈), but less difficult enemy puzzles (💀) which are an optional way to get a tricky digit. Fight as many or as few enemies as you want to finish your quest!
Bosses in Sudokuvania 2 are a smiling imp icon, while enemies are a skull icon.

Perhaps, after Lineage of Logic is finished. I'm unsure of the best way to reduce difficulty without trivializing the logic or completely overhauling the design... but it is still in my mind. I'm sorry for leaving you hanging.

My only regret with Sudokuvania is how unwelcoming it is to newcomers; I did not expect it to find an audience who were coming from a non-sudoku background. That's why the sequel will have a gentler learning curve and ways for the player to adjust the difficulty. (Not easy, but not as brutal.)

I suppose this makes a good occasion to announce the sequel. Sudokuvania: Lineage of Logic will arrive next spring (still on SudokuPad) with a bigger map, more puzzles, optional enemies/unlockable clues, and better "graphics". In the meantime, more of you should work on finding the secret ending...
