Lost

(Published on 21. October 2022, 00:33 by Dathan)

My fifth puzzle, Lost.

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

Rules:

- 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)

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

I enjoyed my 28 minutes. How can you sprint through such a beautiful puzzle?

Funny to see where the fog started. Great fun thx.

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

Super fun puzzle and mechanic! Was extremely satisfying to see how it unfolded.

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!

on 24. October 2022, 23:18 by 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.

on 24. October 2022, 15:11 by Dathan
Updated the solve link to a beta version of the app instead of alpha

on 23. October 2022, 10:17 by Dathan
Thanks Perladel and yeah that's a downside to this. Easy to spoil yourself if you're not careful.

on 23. October 2022, 02:25 by 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

on 22. October 2022, 21:18 by Dathan
Thanks Nicholas Roberts! Yeah I personally like the linear solve path though

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

on 22. October 2022, 20:58 by wenchang
Nice and smooth! Spoiler alert! https://youtu.be/Yeim0iFlPv8

on 22. October 2022, 19:07 by 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!

on 22. October 2022, 14:09 by Drawoon
what magic is this??

on 22. October 2022, 10:14 by Dathan
Thanks Something Wellesian and DogSalvalas!

Yeah the fog really helps to guide the solve path!

on 22. October 2022, 09:51 by 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.

on 22. October 2022, 01:54 by Something Wellesian
What a lovely little puzzle, thank you!

Congrats First Citizen!

Very nice crafted with these "special effects" ;)

Very nice, thank you!

Thanks Chelo and CruzBrun! :)

Very nice GAS version of fog sudoku. Fun throughout!

on 21. October 2022, 17:21 by Chelo
Lots of fun @Dathan, thank you for setting this puzzle!.. The fog feature is a very nice idea!..

on 21. October 2022, 15:00 by 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.

on 21. October 2022, 14:53 by Snaques
Very fun puzzle.

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

on 21. October 2022, 14:38 by Dathan
Thanks GojiCrafter!

on 21. October 2022, 13:56 by GojiCrafter
This variant is so much fun, thanks for making this puzzle!

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

Thank you Lkrptk!

on 21. October 2022, 12:39 by Lkrptk
That is super cool, I really really enjoyed

on 21. October 2022, 11:52 by 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. :)

on 21. October 2022, 11:48 by 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!

on 21. October 2022, 06:02 by gonzalez87
Love the concept, the shadow worked great. Hope to see more of those!
