I love this Channel in its current form. ❤ Please please please don’t get tempted to change your content or form 🙏🙏🙏🙏 I think this channel has something unique. A significant amount of followers are spending 1-3 hours a day on the current content. It’s focus time. Don’t think Beasts does. (Just guessing here) You are both sweet and kind, and the world needs more of that. And Sudokus. 😅
I have been watching for a few years now, and your videos have been a constant source of comfort to me. Both during the pandemic and throughout pregnancy and into the toddler years now, I have watched your videos every night before bed or during 3am wake ups. I used to do crosswords with my grandma and now enjoy doing them with you, and you opened my eyes to sudoku being more than just classic and inspired a whole new hobby within me. I think your channel is wonderful just as it is and it has a massive positive impact on thousands of people around the world. Thank you x
You absolutely nailed it! Thank you so much for playing, Simon! I'd also like to mention that I'm not personally working on an 8x8 version, but that's because I've loved the fact that different setters have set each of the 4x4 (by jordanp301), 5x5, 6x6, and 7x7 versions, so along with Simon, I'm setting the challenge for another setter to enter the arena! Good luck! *Spoiler Bit:* I did try to make sure it wasn't necessary to figure out the 3 cage for those people who didn't want to go down the full mathematical route, so you can get 29 as the forced maximum for the large Row 3 cage and 31 as the forced maximum for the large Column 2 cage. After that, it is naturally possible to figure out it has to be 41 and 3, but also Sudoku does determine the 3 cage in this instance for those that prefer that route. :) - Mega "Xenonetix" Lamb (P.S. Although I'm not trying to make 8x8, I have some ideas for 9x9 in a regular Sudoku grid I'm experimenting with already :P) Logic Masters Germany Puzzle ID: 000IAI
Wasn't there a 3x3 version somewhere too? I remember solving one on Logic Masters Germany but I can't find it anymore (probably deactivated or I'm hallucinating)
@@felis_timon Yes, there's a 3x3, done by the same setter as the 5x5 one. The reason you can't find it on Logic Masters Germany is they deleted it's separate page and incorporated it as a bonus puzzle on the page for the 5x5 version.
After starting the way Simon did (with the 2, 11, 17 and 19 cages) there is a rather pretty way to make a lot of progress. If you sum up the first 13 prime numbers, i.e. 2 more than there are cages, you'll get 238, or 42 more than the sum of all the digits in the puzzle, which is 28x7=196. This means that all of the first 13 prime numbers are present as sums in the puzzle, except 2 that add up to 42. Because 39 is not prime, 3 must be a cage total and can only be in the 2 cell cage in row 2. Now, because there is no other cage where 5 can fit in, 5 and 37 are the primes you are leaving out. Once you know all the cage totals, it's rather straight forward. Nice puzzle, thank you for that. :)
I have zero mathematical knowledge - it's a complete blind spot to me, in fact adding anything other than single digits brings about a total mental freeze- but I love these puzzles and I'm very slowly starting to understand things eg what a triangular number is (and The Secret of course). I'm sure all this stuff is simple to most people but, hey, we are all different. Primes are still a mystery but I really do love these videos and I love watching you solve the puzzle. Thanks so much.
Definitely jumping into this one without the earlier two made it a bit more challenging for me but I persevered and (with some clever counting deductions and realising as you say that the small number must be a 2) I managed to solve it in around an hour and fifteen minutes without any watching of the video. A very fun solve!
I finished in 50 minutes. 'm really liking this series of puzzles. Each one has been completely unique in its break-in and it's wonderful. I really liked this break-in, utilizing the three 5 cell cages to create a barrier for the lower primes. I can't wait to see who creates the 8x8. Great Puzzle!
I've been following since the pandemic, i downloaded the app of Sudoku provided by you guys, i appreciate the entertainment and for me to have a new way to pass the time.
Solved in 23:53. It took me a bit to figure out the invalid prime cage sums, but the logic of how valid sums complement the cage shapes was such a nice trick.
There are now also Mystery Killer Primes puzzles at 3x3 and 4x4 sizes. Those are too easy for your channel, but I like that every option going down in size has been covered.
Finished in 15:47. That was fantastic! Great deductions every step of the way. Was definitely slower catching the deduction for the single cell cage than I should have been.
There's a slightly simpler way to deduce the values of the 5-cell R1 and C1 cages. The math on C1 forces R1C1 to 3/7 and the opening logic gives the 2 in R1C7. If R1C1 was a 3, the cage would have to sum to 5 (as an 11 cage would require an non-existent 8 to make the sum), making it a 2/3 cage. That would mean both 5 cell cages in R1 and C1 would be missing a 2 and 3, thus having the same sum.
4:07 As the grid expands the possibilities grow and make these a touch tougher, though still easy, but they are an exceptional feat of compilation to build.
35:39 + about 10 minutes playing around on my phone. I had to pull out my engineering brain and keep tons of notes in a spreadsheet, but it flowed nicely once I started doing that and figured out how to start using Row and Column 1.
Finished in 20:51. I wish I had looked at the sum of all the digits in the sudoku in the first place. That would have made the solve about half the speed if I had started with that. Fun puzzle!
26:44 - I used pretty much the same solve path. I'm glad this one doesn't resolve to using the lowest N primes, so there is a bit of freedom. What I did differently is work out what the bent 5 cell cages are before looking at the total to disambiguate 3 and 5.
5x5 took me under 5 minutes to solve. 6x6 took me about 20 minutes. this one took me a bit over an hour. it was way harder for me to deduce the cage sums, once I figured out the 2, the light blue/yellow/pink (in the thumbnail) cages being 17/19/23 in some order, and therefore black being 11, I got stuck for a while until I did a bunch of math.
You and your content and your audience are in an entirely different universe from Mr. Beast, and I mean that to be the highest compliment and praise. 💓
Took awhile to find the break in but eventually finished in 55:45. The 7 vs 13 cages were available to you as soon as you found the 3 cage because there was no way to fit 2 ones and a two into the 13 cage at that point.
This was the detail that stood out to me. I'm good at intuitive leaps, but have trouble going through all the possibilities when nothing stands out to me as the path forward.
The maths of this was bugging me so I figured out the general case for the sum total of a sudoku/latin square grid of size n and it's 0.5 x (n^3 + n^2) or, alternatively, 0.5 x n^2 x (n+1). I realise that's not exactly breaking news especially as it's just n times the nth triangular number, but it still felt pretty satisfying. I might be able to sleep now.
I took a different approach to this one. I started out by figuring out the one-cell cage in the upper right corner, based on parity. Since every prime except for 2 is odd, adding up all the other cages gave an even number, which meant that cell had to be even. From there, I figured out the upper and lower bounds for each cage, and noticed that three of the cages (the five-cell cages in each of row 1, row 2, and column 1) could only be 17, 19, or 23, which meant those three prime numbers were reserved. My next focus was column 1, to figure out the possibilities for the two- and five-cell cage options, then finding specific options for r1c1, r2c1, and r2c1. From there, I didn't see a great option forward, so I wrote a Perl script to take each of the possibilities for each cage, find all combinations that don't include duplicates, and then display only those results that add up to 196. There were many options, but I could reduce those based on the work in rows 1 and 2, and how r2c2 affects the cage it's in. There were only a few left, and they basically lined up with the tiny cage being 3, the huge one being 41, the two four-cell cages being 7 and 13, and the two remaining cages being 29 and 31 in some order. And finally, it was sudoku to figure the rest out. My time today, including the time to write the Perl script, was 34:00 even, solver number 4615.
That was fun. When I realised I had made a mistake I thought nothing about just restarting from the beginning because it was very enjoyable. Approachable.
Simon figuring out the 13-cage couldn't be the 7-cage way after he could have - once he got the 3-cage, the 4-cell cage below could not be the 7-cage because the 2 would have gone in r4c5 and 1 would have to go in r4c6, leaving no place for the other 1 that is required.
I googled the sum and got this "gem": The first 11 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. Finally, their sum is 129.12 Oct 2022 Something tells me AI is up to its usual shenanigans as that is _obviously_ wrong, for reasons Simon stated early in the video,.
16:41: "This is either 19 or 23" I'll do you one better. If it's 23, then r1c1 is a 3. We know that r1c1 and r2c1 add to either 5 or 11. We can't put 8 in this grid, so if r1c1 is 3, they have to sum to 5, where r2c1 is a 2. But now to complete the sum, the rest of column 1 needs to sum to 23, which would give us two 23 cages, which isn't allowed. It follows logically that the cage in row one CAN'T sum to 23, so it must sum to 19.
After two complete restarts, I solved it in 33:29 clock time, though I did spend more than a little time now and then with Excel and figuring out which primes to include (and, more importantly, which to exclude!). I had a false start thinking that -42 would play a role ;-)
Some time ago, someone posted a comment on a CtC video suggesting Simon could take a tip or two from Mr Beast, on how to make the channel better. Not being familiar with Mr Beast's work, I rather foolishly suggested that perhaps it should be the other way round, with Mr Beast taking advice from Simon. I was fairly quickly educated on the success of Mr Beast's TH-cam channel. I guess I now have to concede, it does appear that Mr Beast is quite successful, and may indeed know a thing or too about producing TH-cam content. 😂 (The TH-cam algorithm still doesn't think it worth while recommending his videos to me though. 🙂)
That grid made my head spin around. Those primes simply would not calm sown. Every one went through rages Till I put them in cages Of chartreuse, magenta and brown.
I'll continue my regular pitch that 2 in the corner deserves a song too: Carly Rae Jepsen's If You Know What I Mean! Not that I expect it to be Simon's cup of tea 😂
No song by that name came up. I Didn’t Just Come Here to Dance repeats the line a few times. Is that the song you wanted us to find? I'm guessing I found it. "It's you, boy, you in the corner." This doesn't feel nearly as meme worthy as a widely known R.E.M. classic. All that said, watching him sing that line in this video would have been good silly fun.
It's funny that the total sum of sudoku grid is only odd for 4k+1 sized grid (so sudoku with 1, 5, 6, 13... rows/columns), and all other have even total sum.
The rules don't even say that sodoku rules apply (there are no 3x3 grids, so maybe just the rules about digits repeating in a row/column), so his assumption that the total sum is 196 isn't necessarily true because digits could repeat in rows and/or columns. Also, this would mean that the top left 1x2 cell could be two ones to make the even prime IF the total sum was 196, in addition to many other conflicts that would arise
I didn't watch the last prime puzzle video so I didn't find the single cell cage is 2. But I noticed the 17,19,23 triple and the prime domino should be 5 or 11. So I added up the column 1 and row 1&2 as 28*3 = 84. 84-(17+19+23) = 25 which is single cell prime + 2 * prime domino + r2c2. if prime domino is 5 then single cell is 7 and r2c2 need to be 8. So it should be 11 and single cell prime + r2c2 = 3. Bingo! Another difference is I didn't got 41 so early. In fact I checked that when I need to decide the 3 or 5 domino after I have cracked 29, 31, 7 and 13 cages. It's easier to check 39 or 41 than minus lots of numbers from 196. My time is almost double than Simon. I believe the root cause should be the basic sudoku skills and I rely on the pencil marks too much. Every time I know the sum of cages I would fill in all the possible numbers. Then I have to spend a lot time to remove them.
my first thought: the puzzle is broken. because 45 is odd, and all primes except 2 are odd. If you have an odd cage in column 1 the other one is even..............3......2.....1......ohhhhhhhhhhhh 7x7 not 9x9. LMAO
Sorry, but I have to confess that adding *primes* is a boring excercise to me. Primes are just a bunch of weird numbers, that I cannot even remember. Moreover, this is not even an original ruleset. By the way, I used a spreadsheet as an aid memoire, and to quickly compute subset totals, but that was not enough to make this puzzle enjoiable to me. And the same was true for the 6x6. Only the first one, i.e. the 5x5, was fun as it was at least original.

I'm looking forward to it!

I do 12 hour shifts, and like to print out semi approachable ones like this that a few of us work on through out the day. We love it.

I remembered the previous primes puzzle and immediately paused the video to count the number of cages to see if the single cell cage is a 2.
That 2 cost me a lot more effort. It's always a pleasure watching Simon after having solved it myself and see what he saw that I didn't.
Simon and Mark, I love your channel. It means so much to me and I hope you guys keep doing you ❤️
I don’t often care for the non normal sudoku rules puzzles, but this one was a treat. The prime puzzles always tickle me to watch them

solved in 8:39 - good logic along the first two rows. very glad to not have to compute the exact total of the largest cage
It took me almost as long to find the break in as Simon's entire solve time, but I solved it.
Finished in 15:47. That was fantastic! Great deductions every step of the way. Was definitely slower catching the deduction for the single cell cage than I should have been.
Finally! Discovered this a few days ago on LMG but couldnt solve it and have been waiting for this video since.

the 17-19-23 cages is such a nice constraint

Took awhile to find the break in but eventually finished in 55:45.
The 7 vs 13 cages were available to you as soon as you found the 3 cage because there was no way to fit 2 ones and a two into the 13 cage at that point.
This was the detail that stood out to me. I'm good at intuitive leaps, but have trouble going through all the possibilities when nothing stands out to me as the path forward.
Interestingly if you know your square numbers, 28 x 7 is the same as 14 x 14 since you can halve one and double the other.
Halve and double is such a time saver in mental mathematics! One of my favorite techniques.
The maths of this was bugging me so I figured out the general case for the sum total of a sudoku/latin square grid of size n and it's 0.5 x (n^3 + n^2) or, alternatively, 0.5 x n^2 x (n+1). I realise that's not exactly breaking news especially as it's just n times the nth triangular number, but it still felt pretty satisfying. I might be able to sleep now.
33:33 I'm quite new to Sudoku puzzles and that's very good for me.
I do wonder if "Maverick" (or any one of the "Mavericks" that grace your videos) have any clue that they feature in your videos? :D
41:46 - Very nice.
Finished in 32:51 by following along with the video.
15:05 for me, was really happy with that.
I took a different approach to this one. I started out by figuring out the one-cell cage in the upper right corner, based on parity. Since every prime except for 2 is odd, adding up all the other cages gave an even number, which meant that cell had to be even.
From there, I figured out the upper and lower bounds for each cage, and noticed that three of the cages (the five-cell cages in each of row 1, row 2, and column 1) could only be 17, 19, or 23, which meant those three prime numbers were reserved.
My next focus was column 1, to figure out the possibilities for the two- and five-cell cage options, then finding specific options for r1c1, r2c1, and r2c1.
From there, I didn't see a great option forward, so I wrote a Perl script to take each of the possibilities for each cage, find all combinations that don't include duplicates, and then display only those results that add up to 196. There were many options, but I could reduce those based on the work in rows 1 and 2, and how r2c2 affects the cage it's in. There were only a few left, and they basically lined up with the tiny cage being 3, the huge one being 41, the two four-cell cages being 7 and 13, and the two remaining cages being 29 and 31 in some order.
And finally, it was sudoku to figure the rest out.
My time today, including the time to write the Perl script, was 34:00 even, solver number 4615.
Warning: this is a very good puzzle! Also, very Xenonetix..
bro you level of intellect always blows me away man
That was fun. When I realised I had made a mistake I thought nothing about just restarting from the beginning because it was very enjoyable. Approachable.

I have no clue who MR beast is.. honestly - besides heard his name a few times. But this channel.. - gold!!
My gosh... I was like "the video is 34 minutes long. I'm currently on the 28 min mark, and the boxes still looks rather empty..." but then...
I googled the sum and got this "gem":
The first 11 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and 31. Finally, their sum is 129.12 Oct 2022
Something tells me AI is up to its usual shenanigans as that is _obviously_ wrong, for reasons Simon stated early in the video,.
16:41: "This is either 19 or 23"
I'll do you one better.
If it's 23, then r1c1 is a 3. We know that r1c1 and r2c1 add to either 5 or 11. We can't put 8 in this grid, so if r1c1 is 3, they have to sum to 5, where r2c1 is a 2. But now to complete the sum, the rest of column 1 needs to sum to 23, which would give us two 23 cages, which isn't allowed.
It follows logically that the cage in row one CAN'T sum to 23, so it must sum to 19.
After two complete restarts, I solved it in 33:29 clock time, though I did spend more than a little time now and then with Excel and figuring out which primes to include (and, more importantly, which to exclude!). I had a false start thinking that -42 would play a role ;-)

The rules don't even say that sodoku rules apply (there are no 3x3 grids, so maybe just the rules about digits repeating in a row/column), so his assumption that the total sum is 196 isn't necessarily true because digits could repeat in rows and/or columns.
Also, this would mean that the top left 1x2 cell could be two ones to make the even prime IF the total sum was 196, in addition to many other conflicts that would arise
“Each row and column contains the digits from 1 to 7 once each” - Latin square rules, digits can’t repeat
Mate, it’s the first line in the rules.
Brilliant puzzle.
I didn't watch the last prime puzzle video so I didn't find the single cell cage is 2. But I noticed the 17,19,23 triple and the prime domino should be 5 or 11. So I added up the column 1 and row 1&2 as 28*3 = 84. 84-(17+19+23) = 25 which is single cell prime + 2 * prime domino + r2c2. if prime domino is 5 then single cell is 7 and r2c2 need to be 8. So it should be 11 and single cell prime + r2c2 = 3. Bingo!
Another difference is I didn't got 41 so early. In fact I checked that when I need to decide the 3 or 5 domino after I have cracked 29, 31, 7 and 13 cages. It's easier to check 39 or 41 than minus lots of numbers from 196.
My time is almost double than Simon. I believe the root cause should be the basic sudoku skills and I rely on the pencil marks too much. Every time I know the sum of cages I would fill in all the possible numbers. Then I have to spend a lot time to remove them.
a nice way to the solve, especially in the first part. The second part could have been quicker, as 39 = 3*13 isn't a prime.:)
Mr beast caters to people with the attention span of a peanut whilst Simon's videos are for a more intelligent clientele.

my first thought: the puzzle is broken. because 45 is odd, and all primes except 2 are odd. If you have an odd cage in column 1 the other one is even..............3......2.....1......ohhhhhhhhhhhh 7x7 not 9x9. LMAO
wow, solved in 20:44 😎
Did he learn this from agadmator aka the chess channel legend? 8:30
31:21 for me.
You guys should play 'Ouros' for your next livestream sessions. Great puzzle game.
That's disappointing ...thought one can solve all the
37:50 and I am proud of my time
11:46 for me. Nice puzzle again, but they might be getting a little bit repetitive at this point...
To be honest I’m not subscribed to Mr beast. I am subscribed to cracking the cryptic.
This is epic 🎉
Sorry, but I have to confess that adding *primes* is a boring excercise to me. Primes are just a bunch of weird numbers, that I cannot even remember.
Moreover, this is not even an original ruleset.
By the way, I used a spreadsheet as an aid memoire, and to quickly compute subset totals, but that was not enough to make this puzzle enjoiable to me.
And the same was true for the 6x6. Only the first one, i.e. the 5x5, was fun as it was at least original.

Woooo
Simon, if you ask all your subscribers to help mr beast, he would return the favour in spades. You might get to 2 million in a heartbeat.
