My fifth puzzle, Lost.

Inspired by Chameleon's fantastic Lumos Maxima.
Made possible by Sven's Sudokupad quickly implementing this feature.


- Normal sudoku rules apply.
- Killer: Digits in cages must sum to the small number in the top left corner. Digits can not repeat within cages.
- Thermo: Digits on thermometers must increase from the bulb end.

The grid is covered with fog. There are two initial light sources that illuminate the darkness and clear the fog. Put correct digits into the cells to get more light (it's ok to put a digit into a cell that is covered by fog). There's no guessing required to solve this puzzle. Try not to put wrong digits in the fog as that will eliminate possibilities and make it less fun!

Solve it on CTC (Includes solution)

Lösungscode: Column 1 and column 9 from top to bottom (18 characters, no spaces)

Fun, thank you! I started out thinking the thermometer was an arrow that summed to the circle, so was glad the fog helped me realize my error early on.

I'm not sold on fog puzzles yet but I enjoyed this one

Thanks craig9! :)

That was an extremely enjoyable puzzle. I have never seen the fog of war applied to a sudoku before. Great feature! Thanks.

Thanks and congrats Eraelan!

For a low level/easy puzzle, I found this quite enjoyable. It was my first foray outside of standard sudoku, and not too difficult to grasp the concepts.

am 24. Oktober 2022, 15:11 Uhr von Dathan
Updated the solve link to a beta version of the app instead of alpha

am 23. Oktober 2022, 10:17 Uhr von Dathan
Thanks Perladel and yeah that's a downside to this. Easy to spoil yourself if you're not careful.

am 23. Oktober 2022, 02:25 Uhr von Perladel
Chameleon's idea was amazing and this puzzle is very fun as well.
Unfortunately you have to be careful not to misclick otherwise you discover the clues anyway

am 22. Oktober 2022, 21:18 Uhr von Dathan
Thanks Nicholas Roberts! Yeah I personally like the linear solve path though

And thanks wenchang for the video! Very fun. :)

am 22. Oktober 2022, 20:58 Uhr von wenchang
Nice and smooth! Spoiler alert! https://youtu.be/Yeim0iFlPv8

am 22. Oktober 2022, 19:07 Uhr von Nicholas Roberts
Nice new form of revealing the grid.

On the negative side, I think it telegraphs the solve path right at the beginning.

On the positive side, it was really fun to "clear the fog" as the solving went on.

The future of sudoku!

am 22. Oktober 2022, 14:09 Uhr von Drawoon
what magic is this??

am 22. Oktober 2022, 10:14 Uhr von Dathan
Thanks Something Wellesian and DogSalvalas!

Yeah the fog really helps to guide the solve path!

am 22. Oktober 2022, 09:51 Uhr von DogSavalas
Great puzzle. As I struggle with most puzzles over 1 star, I felt tutored through the puzzle thanks to the fog following me step by step and pointing me into the next area to focus on.

What a lovely little puzzle, thank you!

Very nice GAS version of fog sudoku. Fun throughout!

am 21. Oktober 2022, 17:21 Uhr von Chelo
Lots of fun @Dathan, thank you for setting this puzzle!.. The fog feature is a very nice idea!..

am 21. Oktober 2022, 15:00 Uhr von Dathan
Thanks Snaques! And yeah, Chameleon's implementation gave you some lives that would disappear if you put in a wrong digit, allowing you only a couple of wrong guesses/mistakes before 'failing', but you're always gonna be able to cheat with puzzles like this I guess.

am 21. Oktober 2022, 14:53 Uhr von Snaques
Very fun puzzle.

While certainly fun, the fog could be tricky mechanic to implement in a way that can't be "exploited".

Thanks GojiCrafter!

Thank you for the great puzzle, Dathan! The solve was a lot of fun and it was very approachable.

Thank you Lkrptk!

That is super cool, I really really enjoyed

am 21. Oktober 2022, 11:52 Uhr von Dathan
Thanks Guillem98, check out Lumos Maxima if you haven't!

Yeah the fog works well (thanks to Sven), what I meant in the post is that you can theoretically eliminate options from cells very easily by just putting the numbers in and it will become obvious whether your guess is right or wrong, but that takes the fun away. :)

am 21. Oktober 2022, 11:48 Uhr von Guillem98
This was incredible, I did some testing before starting, and if you put a wrong number in a cell the fogged cells that covers the cell won't get unfogged. But it is spectacular. Thanks for that Sudoku

Thanks obi, gonzalez87 and ImMitchell! I also hope we see more of these!

Loved seeing a GAS version of Chameleon's puzzle. Great new twist to Sudoku I hope we see more of!
