Having barely escaped a space-pirate ambush, your damaged ship all but crash lands on unexplored planet Sudoku-45. With all your equipment scattered after the violent entry, and the ship’s navigation system refusing to work, you have nothing but instinct and puzzle solving skills to get you back home.
If you're playing this in SudokuPad, consider turning ON the following settings for a better experience:
This puzzle was heavily inspired by Skeptical Mario's fantastic puzzle "Sudokuvania: digits of despair". Consider checking it out if you haven't. However, this puzzle should be significantly easier for the most part.
Instructions
This is a dynamic, expanding puzzle, consisting of multiple, partially overlapping Sudoku grids. Selecting a cell will update the puzzle description with the rules of that sector.
Most of the grid is covered in fog. By correctly placing digits, the fog may be lifted. You may place digits in the fog if you know what they are, but otherwise avoid clicking on covered cells to not get spoiled by undiscovered areas or rules.
Each sector is a complete Sudoku of its own. Areas may overlap, in which case the overlapping parts belong to both sectors, but digits entirely within one sector does not affect digits within other sectors (meaning digits can share a row or column as long as they belong to different puzzles).
In the top-right corner is a list of learnt rules. You may only use a clue if you have unlocked it in this list, even if you think you know how it works! You can click on any of the displayed rules to get a more detailed description and some basic hints on how to apply it.
Most sectors have a boss. When you discover the boss cell (indicated by an angry emoji), use the link in the sector's description to play the boss puzzle.

Hi! I'm not sure I understand the solution code request. Which end of the evac line is it asking for? I tried both and neither was accepted...

There is a way to resolve the deadly pattern if you keep exploring the map.
As for the Reservoir, you need to do a little bit of Sudoku to progress. There's a digit you can place out in the fog that will reveal more (don't overthink this one, it's simple).

The boss links are intentionally part of the sector descriptions. I could have revealed them when you click on the boss cell but I was afraid people would miss them or forget about the boss rules if I didn't show the link earlier. Obviously, don't try solve the boss puzzle in advance ;)

The boss battle links are appearing as soon as I place a digit in the sector, LONG before I've uncovered the boss cell. Is this the intended behaviour?

If there was ever to be a primer on Variant Sudoku, this would be it. Excellent puzzle, no notes.

Took me 7.5 hours for my solve, done regrettably all in one session. Truly an amazing puzz, but I def should've taken more than one day to play all of it lol.
Almost all the boss puzzles were truly fantastic, I especially loved the Queens and Bishops boss.

I'm struggling to understand the teleporters. I thought I knew what one value had to be, but error checking said a different value is right that seems impossible.

And thus, the Sudokoidvania genre is born.
