Arthur followed Ford's finger, and saw where it was pointing. For a moment it still didn't register, then his mind nearly blew up. "What? Harmless? Is that all it's got to say? Harmless! One word!" - The Hitch Hiker's Guide to the Galaxy
Normal sudoku rules apply: fill the grid with digits 1–9 so that no digit repeats in any row, column, or 3×3 box.
All variant clues follow their standard meanings; full descriptions are provided below.
Secondary Phase airing later this year with Mostly Harmless: Babelfish...
Lösungscode: Row 3 - left to right

Nice puzzle! Also just wanted to thank @Narayana for linking to my puzzle - thank you!

indeed, took me a minute to figure out the end as well...
Sure, reading the rules helped, seeing what is indeed missing and such, but it's not as low hanging of a fruit as the rest has been... still a very beautiful puzzle

Not by me. It is a very nice puzzle that needs more solves and has a Hitch Hiker's theme.

Yep, no guessing needed, but I can understand the struggle with the last step. I had to bifurcate a bit to figure out the technique I was missing.

This does solve uniquely without making assumptions on contents of the fog.

11:22 For me. R7C2 and R7C3 are ambigous, there's no hint how they should collapse. Had to guess. The maximum hint showed up too late for me.

This is a great puzzle, the last thing is a little hard to spot but not THAT hard!

This puzzle was mostly harmless. And mostly 1 star difficulty :)

I"m stuck with a few boxes on the left side of the puzzle. Probably something obvious I'm missing. Haven't seen the maximum rule pop up yet.

I think this solves fine as it is - I put a hidden comment on my final resolution.
