** TODAY'S PUZZLE **
Mark sends Simon a puzzle to open on camera this evening... it's called 1919 Sandwiches and it's the most unbelievable construction from American Math Teacher, RockyRoer. Prepare to have your mind-blown!
Play the puzzle at the link below:
app.crackingthecryptic.com/su...
Rules:
Normal sudoku rules apply. A digit in row 1 indicates which row contains the 1 in that column. Eg if r1c4 was a 6 then 1 would appear in r6c4. A digit in row 9 indicates which row contains the 9 in that column. A digit in column 1 indicates which column contains the 1 in that row. Eg if r7c1 was a 4 then 1 would appear in r7c4. A digit in column 9 indicates which column contains the 9 in that row. Clues outside the grid indicate the sum, or parity of the sum, of the digits sandwiched between the 1 and 9 in their rows/columns.

I really thought that by now, Simon would know better than to say that he thinks a puzzle is impossible before trying to solve it 😏

@Squishy3757 Год назад

I was just going to say, I love when Simon exclaims that the puzzle is impossible and then goes on to solve it.

@matthewmayton1845 Год назад

To be fair, Simon has suggested that over the last couple of years, for every puzzle they solve, there's about 3 to 4 they cannot. I believe this was in the short run podcast Simon and Mark diid.

@TrackpadProductions Год назад

@@matthewmayton1845 There is also a difference between a puzzle they can't solve, and a puzzle that's unsolveable, though. Unless that's what he meant, but it seems unlikely...

76 min for me. Wow. The standards these days are just ridiculous. I love these types of puzzles where the logic creates correlations between cells. It reminded me of Phistomefel's Ancient Wall puzzle. Yet another masterpiece. And it shows what Simon & Mark have accomplished: thanks to their channel, puzzle creators are pushing themselves and each other to come up with puzzles we never thought possible. It's just beautiful.

@Hemigoblin Год назад

You’ve got a few “wow”s marked at 52:51 which are actually we’s and well’s. You’re still miles ahead of Alexa, because you never interrupt Simon’s train of thought during the solve! Thanks for posting these; it’s always fun to see the breakdown.

@cephalosjr.1835 Год назад

2:04 and 2:07 contain instances of “you rotten man”, which probably qualifies as a Simarkism. It might be close enough to go under “you rotten thing”.

@afrayedknot81 Год назад

From 41:56 onward, you could use the pencil marked 4s in b3 to see that 9 can’t be in those same two cells. In either case, it would make the c7 sandwich even.

@steveamsp Год назад

Really proud that I was able to solve this puzzle without any help. 88:53 was my final solve time. breaking in was tough, but the indexing provided so much information, that you are able to just go on a run for a bit, then when you get stuck, the sandwich clues give just enough information to keep you going. Props to the setter :)

this solve really impressed me because at a base conceptual level I struggle really badly with even following along on these indexing puzzles. i like to try and think ahead on the puzzles, where it should go, what i'd look at, since I don't solve many sudoku puzzles in my own time. I kept messing up the logic on the 1/9 corners with my brain going 'those cells can't exist it's broken it would overlap' until simon worked it out giving me a big dose of, 'oh, right, ok.'

60 minutes almost on the dot! This was a delightfully ingenious puzzle. At a certain point the logic just clicked for me in the sense perimeter was almost like 2 axises to a coordinate grid, and the rest of the solve went pretty smoothly. I especially like the fact that the odd and even parities come along really helpfully the moment you've done the sandwiches and are determining the other digits. Would love to see a construction video on this one too.

@RoderickEtheria Год назад

My first two questions were instantly "Where can 1 go in b1?" and "Where can 9 go in b9?" Each of these has only 3 possible answers. For b1, 1 can only be in r1c1 if it is in either r1 or c1, because each part of the reference digits must contain a low, a medium, and a high. If it is in neither r1 nor c1, it must be referenced by a 2 and a 3. Likewise, you can restrict 9 to exactly r7c8, r8c7, or r9c9. There are further restrictions based on the 4 total in r1 leading to a 9 in r3c1 if r1c1 is a 1, but this means between r1c3 and r9c3, a 35 total would be even.

@sonalita_ Год назад

As a software developer, I wholeheartedly approve of any and all indexing puzzles. This one was a dream to solve. absolutely brilliant. Simon could have solved this much faster if he’d used all the available indexing logic but it is tricky if you’re not used to it.

I was screaming around 45:00. Those pencil mark 4s in column 7 interact with 9 and the odd sandwich clue. 9 cannot be in r2c7 because then we get a sandwich sum of 0, and it can’t be in r3 because then 4 would be in row 2 and that’s still even.

You did it!!

I love your videos. Just wondering how you become a test solver? Can I apply somewhere? 😂

@joethornton5321 Год назад

Not too long ago Mark solved a similar puzzle. Having solved that made this not too difficult, but it made me wonder if Simon and Mark don't watch each other's solves. For some reason I just assumed they do.

I think that for some of these puzzles where you're approaching it blind, it might be even more entertaining if you read the rules before looking at the grid… the rules sound moderately sensible until you see how few clues there are

Refuses to look at the odd parity clue in column seven and still manage to solve it somehow, wow!

@Iggy363 Год назад

Just watching Simon dance all around the 9 can't be in column seven in box 3 because of the odd clue... so close so many times, yet ending up finding it in a completely different round about way is so amusing... even to the point of checking the 2 possibility for indexing but skipping checking the 7, so close and yet so far away

56:37 for me. A little disappointed Simon resorted to pencil marking. Once you realize there is one row and one column where the 1 and 9 are referencing each other, it is fairly straightforward to narrow those options down to Row 5&6 and Column 4&5, and then the 4 sandwich clue eliminates Column 4 as an option. That was my break-in. The parity clues were very useful as they could be applied to both the sandwich values and the 'outies'

These indexing puzzles just break my brain into tiny little unusable pieces. I cannot ever wrap my head around them.

I got a 22:00 and I almost feel like I must've made some weird logic mistake that ended up just working for me to be that fast... Usually I'm not nearly this quick on index puzzles.

Well, I would say you have gone Full Beast mode.

I found the break-in much more easily by working solely on R1. We know the sandwich has to be 149, and we know more or less where it lives based on the value of R1C1 (sometimes there are two options for the order), and when we place the 149 we also can place 1s in the respective columns. It's fairly easy to see there is only one possible fill for R1C1 using the vertical sandwich clues.

Im hoping this nemesis is singing versions of REM songs revealing all the secrets.

We are one rule away from Miracle Sandwiches 😜

58:42 The other way to get the 6 being if the sandwich filling is odd the digits outside the sandwich must be even, and since they're an 8 + 4 + two other digits picked from 367, and the only way to make that even is to lose the 6...

@bass2564 Год назад

48:16 Highlights the key square for considering the sandwich clue in column 7, which would instantly place the 9 in box 3: "I don't think I'm a million miles away..." No, you're really not. :-)

27:00 for me. Fantastic puzzle!!

@_-_-Sipita-_-_ Год назад

34:14 for me. splendid sudoku. by the way, the C7 odd was not needed to solve the sudoku.

@energythief Год назад

51:00 the easier solution was staring at him for 10 minutes. By using the odd clue at the top of column 7, he would have realized 9 could never go in column 7 in box 3.
