After an amazing first couple of days, we have hit the target to make the book! Now we just hope we can reach the stretch goals to include the new puzzles!! Please help us get there if you can!
**********************************************************************
▶Today's Puzzle◀
Today's puzzle looks incredibly daunting - no digits anywhere - but the author, udukos, was worried we'll find it too easy!! You can play it here:
app.crackingthecryptic.com/we...
Rules: Normal sudoku rules apply. Digits may not repeat within a cage. Within every 3*3 box (marked by thick black lines), all the killer cages have the same sum. Also, killer cage sums are unique for every 3*3 box i.e if box 1 (top left box) had killer cages each of which sum up to 10, then none of the other boxes can have killer cages with a sum of 10. The killer cage sums are not given and have to be deduced.

Your mention of a box needing a negative number made me wonder, could a Killer Sudoku be set where all odd values are treated as negative? So a box with 6 7 8 would 'sum' to 7 (6+8 - 7). Could call it "Odd ones out" as you are subtracting the odd ones.

@danieldreamgazer3934 3 года назад

I don't get the puzzle. Are there special rules that are different?

@davidallen1459 3 года назад

@Daniel Dreamgazer yes, this sudoku includes some special rules in addition to the normal rules. So, besides rows, columns, and 3×3 boxes all needing to have digits 1 through 9, this one includes "Killer Cages" (which are difficult to see here). The the KC are sets of squares whose digits have to add up to certain values. In this puzzle, the KCs are all within the standard 3x3 boxes (no crossing borders), and have to have a value equal to the other KCs in their 3x3 box (so, if one KC in a certain box has, say, digits 1, 5, and 9, which sums to 15, then any other KCs in the box also have to sum to 15 with their digits). Some squares within 3x3 boxes are not part of KCs. The final extra rule for this particular sudoku is that the KCs within each 3x3 box have a value that is unique from the KCs in all the other 3x3 boxes. @Cj Mars This means that the reason he started where he did (in the top right 3x3) is because it didn't have any squares that weren't part of a KC, which means that he could divide the standard 3x3 box total of 45 by the number of KCs in it (three), to figure out that they each shared the sum of 15. His next step, in the top middle box, I think was chosen because it had only one square that wasn't in a KC, so he narrowed it down to the three digits it could possibly be using similar division logic.

@ronalronal5713 Год назад

he started in the top right becuase it was completely filled in with cages so he was able to figure out what the cages were worth in that particular box (15)

Then spaced out on how the 4 and 7 in box 4 fix the place of the 7 in box 1 -- which cracks the whole rest of the puzzle very quickly. I had enough information right there and just didn't see it; gave up and went to watch dear Simon, who got to where I'd got in about 15 minutes, did not miss the essential clue, and unravelled the rest quickly. Still, I had the main ideas, so I'm giving myself credit for a moral victory!

@RichSmith77 3 года назад

That was tough, yet brilliant. I had to give up last night, was too tired for this beast. Managed it this morning, but took around 90 minutes Similar path as Simon, although my reasoning behind the early 9 in box 2 was slightly different. I had the options down to 3,6,9 the same; and the 7,8,9 triple in column 5. This meant 7,8,9 had to appear in c5 or 6 in box 2. If all three of them were in the two cages in those columns in box 2, then one of the cages would have to have (at least) two of the digits, making the cage sum to at least 15. But then all three cages would have to sum to at least 15, breaking the 45 limit on the box. Therefore, one of 7,8,9 has to go in the free cell in box 2, and from the options, this has to be 9.

Definitely got this channel for a reason and I quite enjoy watching and now starting to do sudokus again.

@CraftyTurtle317 3 года назад

I loved this one. Once I heard the 'rules', I paused the video, drew the grid, and started to solve it. When I got stuck, I came back to the video, and watched. You did exactly what I had done. Then you gave me a weeny hint, so I paused again, and managed to solve the rest. Phew! It took me 3 hours though. Kudos for doing in only half an hour. I love your channel.

Well, I just found this channel yesterday! I liked Sudoku for a very long time, however, I always liked playing the EASY ones - I like trying to fill out the puzzles without penciling in any numbers. I felt like I was guessing when having to use penciled in numbers. I watched this and he starts using very simple logic to solve these very difficult puzzles and he has completely changed my mind about what I was doing! I am now watching to learn the logic behind decisions and how to actually solve harder puzzles. Glad I found this channel!

54:07 for me. Took me a while to get started. Once I started putting in digits, it flowed fairly well. Interesting puzzle. edit: Argh... just realized I was trying to eliminate the 6 from the two cell cage in the center box for the longest time and Simon just says "It can't be 15. That's already used in box 3." And I knew that. Completely escaped me when I was solving. I could have saved a lot of time there.

@RufusVidS 2 года назад

I never thought watching someone solve Sudoku could be such a joy! I need that program he uses to fill in the squares with the Possibles and the Must-Bes! He's so quick at noticing things it's a thrill when I see a combination before he does! (Even though I know he'll be hitting it quite soon after.)

@erickehr4475 3 года назад

A truly excellent puzzle. Took me 33:03 which I am more than happy with! I don’t know if I missed anything (and I haven’t yet watched Simon’s solve), but I didn’t resolve the needed sum in box 6 until the very end - and a puzzle which can keep a secret that long is exceptional.

@matthewender3473 3 года назад

Wow, that was brutal. I struggled home in 1:07:21, so naturally I went to check on Simon's approach. Pretty much the same, so the difference was that he could generally see the next thing where I flailed to find it. Well done, good Sir!

@fbrume 3 года назад

Really, really rough (over an hour with interruptions). I felt proud of myself for one early insight: after getting the 789 triple in C4, I realized that 7, 8 and 9 had to go into different cages in the upper-middle 3x3 (since the sums were 12, 13, or 14). That pushed a 9 as the sum of that cage, and led to a nice bit of progress until I got completely stuck as I failed to notice the 78 pair in row 3 for a good 20 minutes. (The separate cages for large values was a trick I then used later on the right and I think one other place.)

@sasukuto 2 года назад

So I've been playing Killer Sudoku for a few months now, just cause I was looking for a good Sudoku app on phone and it was the best one I could find! Then I got recomended your videos this morning and thought they where really interesting so I've been clicking through a few, only to find this video mentioning they you made this app that I really like! Heck yeah! Keep up the good work! I love the app!

I think this sudoku is one of my favourites I've seen on the channel, it's very neat how you can narrow down the possible values that the cages in each box can have based purely on the number and sizes of the cages in those boxes.
