It's a lovely idea to have the solving of a fog-of-war sudoku involve a path or trip through the entire fog-covered grid (with the fog clearing as we approach our destinatin. Just wish there was a finish line drawn onto the grid!
Usually, when I see a long rule set, I don't even bother, but this one turned out to be quite a bit easier than I anticipated and was a lot of fun. Thank you!
37 very happy minutes of my life! In the beginning I did not like the fog puzzles at all, but this convinced me that it is really a pleasure to solve! Greetings from good old Vienna!
Just got back from working in Belgium for a few days so only had fleeting opportunities to view or try the puzzles! Looking forward to this one but going to watch Mr Sleuth first. This was also featured last night on CtC!
19:25 for me. In real life i prefer time without snow as it is cold and very slippery if you need live together with snow in worstest cases nearly half year.
Thankyou Suduko Sleuth for this excellent puzzle. I watched this on CTC yesterday so had some clues on how to start so probably solved in a quicker time than I would have done normally. I then watched your excellent solve as I like to see different solve techniques to learn a lot more puzzler tips as I am still a slow solver. Kind regards Ju
@@SudokuSleuth But sometimes it goes in another direction. I've noted already several times them solving some of puzzles you have already posted. Besides, are you thinking about trying to go for monstrous ones similar to 1+ hour videos on CTC?
Fair point! I guess never say never, but I can certainly say that is not my intent! A) I’m not a reigning champion. I expect many of these puzzles are beyond what I can solve B) I certainly didn’t start this channel to be a competitor, but to promote truly approachable puzzles for the majority rather than the few thousand that can solve some of the extraordinarily difficult ones out there. Unless the audience demand it, I’m going to stick to that mission like glue 😀
Some people have mentioned the same thing, that the between lines can be straight, or can take a turn. The rules don't clarify this. I don't think the puzzle is solvable, if we assume the between lines can turn. In fact, I am stuck somewhere where he is at 26:26, when he assumes there is a 6 either in R6C5 OR R8C5. We actually don't know that! The other end of the 6th between line gate (which is still covered with fog) can be even in R8C4, or R8C6, meanwhile the path is taking the cell R7C5 in between the gate's circles (because we can see a tiny line section pointing down from R6C5, so that definitely means R7C5 is ON the path). Even more, the rules didn't mention if the path can touch itself, or not. In theory, the path can go left from R6C3, and then take a down turn, then a right turn, and go to gate6 all the way back in R7 while touching itself. At this point, the polarity (high or low) of those cells are unknown, so it is not helping us. After all, I think the puzzle would be unsolvable, so I have to assume the gates are straight, and this immediately means there is a 6 in C5 and that also sends a 4 down to R9C5, which is a huge step forward. Similarly, it would be unsolvable, if the path can touch itself. At least I don't see the way out if you carefully check the situation at 26:26
True, but the only ones not revealed at the time he used them were the second gate and the sixth gate, which placing the 3 at that point in the solve would have revealed the truth of the second gate, and the sixth doesn't matter because the effect on box 5 is the same, giving a 6789 quad and a 12 pair which gives the 4 and sorts the skier's path through row 7. Further, you get a 2 in row 4 when you notice the 7 can never be on the X giving a 14 pair. This leaves a 1678 quad in column 3 where you can't have the 1 on the white kropki, Now you have to have the 7 on there so you place the 8 in the column, and then the 1 where you reveal that the sixth one doesn't bend backwards. Now box 4 is sorted, row 4 is sorted. Now column 5 box 5 is sorted revealing the full truth of the sixth gate. Proceed across to the rest of the solution. :)
Once one of the poles is revealed, the beginning of the line connecting both becomes visible. It is quite tiny and can easily be missed. He points this out at 34:17.
Sudoku skiing is fun.
A fast slalom of 27 and 03! Fresh powder, fresh solve!
Just under 35 minutes for me. Really liked the way this flowed.
That's what a nice and doable one! 🦒
Wonderful puzzle

Vienna is one of my favourite cities. Always enjoyed my visits there 😀

Welcome back!
13:16 Nothing in the rules says that between lines have to be straight, so drawing in the line to r1c5 and placing a circle there was not justified

Every time I queue up a few videos Ctc sneak in and solve a scheduled one 😁
Glad you enjoyed it, it’s a fascinating puzzle 😀

18:09 ... clever idea for a puzzle
14:12 second try :)
You can see the line of gate 6 enough to see that it goes down.
@ 24:25 how did you know the #5 gate was horizontal and not diagonal to R7C2? I never could figure out a proof for that.
Once one of the poles is revealed, the beginning of the line connecting both becomes visible.
It is quite tiny and can easily be missed. He points this out at 34:17.
Thank you. I’m sort of surprised I didn’t talk about the lines you can faintly make out until the last gate!
Not too difficult, I finished in 33:56 without any wrong turns.
Excellent puzzle
Glad you liked it
