Thank you for the feature Simon! This was a very pleasant surprise and a great solve as usual. This puzzle was inspired by the tetris themed puzzles in the game "The Witness". Thanks to everyone who recommended this and I am glad you enjoyed the puzzle
for improved clarity next time: you could have used various blue colours for ALL blue tetris shapes, and various brown/orange for the others, re-using the same shade if necessary for shapes far apart. would make the overview much neater and clearer.
I wish Simon would remove the colours from cages that have been determined, since there's no need for them any more. So often he ties himself up in knots trying to find a new colour when he could re-use an old one that isn't doing anything useful any more!
It wouldn't be a Simon solve if he didn't go for a kaleidoscope of confusion and use far too many colours to make it as difficult as possible to work out what on earth was going on...
27:00 Simon forgets the two-piece cage (already proved to be 78) in the top right box. If the top of the T shape occupied R1C7, it could not be 7 or 8 (nor can it be 9). So this T cage contains only one 'high' digit, the three others are at most 456 and the maximum total would be 4+5+6+8 = 23, so that actually disproves the possibility of the T shape touching the top row.
@@rickpgriffin Yah, he missed that a couple puzzles ago as well, when not realizing two 3's were already allocated to a different colored line. Add in some coloring instead of using his pencil marks, and pretty much standard Simon. Using harder logic then needed to solve the puzzle. At least he did realize the top digit could not be a 7 or an 8 eventually this time. Probably because he had to.
This is a classic example of grade deflation - this would never have been 3/5 a while back, but CTC has educated a generation of solvers to ridiculous levels of ability ...
I only recently started watching daily (to fall asleep 😅) but I got recommended videos every now and then for years, I feel like it was not very long ago that Simon was getting really excited about puzzles with 3... Or 2... Or zero(!) given digits... Now he's like, I don't even see the given digits anymore 😂 Really shows the skill development of the setters as well. It really is mind blowing what they manage to find.
this is a 3/5 difficulty. you would also see it as a 3/5 if we didn't spend thirty minutes watching Simon completely ignore the square piece in box 4, which can only contain one of 12 and one of 456
I agree with the 3/5 from a solely personal point of view. I can solve 3/5 on my own with a hard slog, I need Simon's help with a 4 and I've got no chance with a 5. I did this one on my own but it took ages so I reckon 3 is about right 😂
Solved in 72 minutes with no errors, guessing, or hints. Don't think I've solved one this long so close to Simon's time before, especially with no help. It was a smooth, but steady (albeit long) solve.
This is one of those puzzles where my solution path was completely different to Simon's. I manged to resolve most of the bottom of the grid into pairs and triples before moving on to the top part. But I did find a very nice piece of logic I'd like to share. Using 1:02:37 as a reference (although as mentioned I got there much earlier). Box 7 has 3 cells of a green 24-cage taking up a total of 22. (Simon is about to mark them as a 679 triple.) I hadn't yet placed the 2, but as you'll see, that's not needed. The 35 pair in box 8 is also important. Now when considering the placement of the size 15 cage in box 7. It's either: (1) entirely in the box, leaving 45-22-15=8 for the last 2 cells. (2) or it has 3 cells in box 7, and 1 overlapping a 35 in r9c4. But in case (2), the 35: - Can't repeat in the cage, sees the bottom row, and doesn't match anything in the top row of the box. - So that only location for the 35 in box 7 is r8c1 - So, despite the cage not being entirely in box 7, we know the 4-cells r8c1-3 and r9c3 sum to 15. - So, we are still left with the last 2 cells totalling 45-22-15=8. The only difference is the location of those cells. Either (1) r8c3, r9c1 or (2) r9c1-2. And can usually be achieved by 1+7, 2+6, or 3+5. But the first 2 are unavailable due to the 679-triple in the 24-cage. And now if we were to place the 3+5 in (2) r9c1-2, it would break r9c4. Therefore, we can deduce the cage is entirely in box 7. Mark the 2 places for the 35 pair. And trivially set the composition of the cage as: 1248.
to answer simons question about the 3 pencil mark in box 1. it happened at 49:40 where he thought it was the only 2 places for a 3 in row 3, missing the possibility for one in r3c5. luckily he never used the mark and cleared it when he noticed it might be wrong
At 54:57 there was a wonderful opportunity to use the "secret" to resolve the 12 pairs and fill in all the light green 12 digits with their actual value. In box 4, there is a 4-cell, size 15 cage entirely within the box. The bottom row has: a 1 or 2; and a 6 with a 4 or 5. Maximising, we get 15+6+5+2=28. Leaving 45-28=17 for the remaining 2 squares. The 89 pair wouldn't be able to go in column 3 due to the existing 78 pair in box 1. Which resolves: - the position of the 89 pair, - a 2 and 56 pair in the bottom row of the box (differentiating the 12 pairs throughout the grid) - and the cage placed in the top right corner with a 1347 quadruple.
I have noticed that I am not as interested sometimes in the sudoku-game mashup kinds of puzzles, but this one worked very well, I thought, and it was very fun to watch you solve it, Simon. Thanks for the video!
I finished in 105 minutes. What a beautiful puzzle. The theme was excellent and the fact that only Tetris givens were in the puzzle is just extraordinary constructing. I really like this ruleset, it feels so natural to Sudoku. Great Puzzle!
Despite any haters that hate, I think your brain, Simon, is great, For you take ones and twos And from those you deduce The existence of five six sev'n eight.
The first in a long time where I couldn't resist but follow along and solve it myself, playing the video bit by bit whenever I got stuck. 135 mins on sudokupad, over two hours is an awful time, but I'm still quite happy to have solved it, even with help!
At 33:55, Simon finally looked at the 2x2 piece in box 4. It's too bad that he didn't look at the effect that had on the overall box 4 total. He'd have seen that the other bits must all be maximised. The 456s must be 56s, and the 12 must be a 2. Then, the other two digits not part of the 2x2 must be an 89-pair, and that tells you where the 2x2 is situated in the box (to the right).
At 49:40 "Okay, three is in one of those two squares by sudoku in row three. That's almost certainly not we're meant to do next." Yep, because that is a wrong deduction. :D
He saw the pencil marks covering row 1 of that box and assumed that a 3 in the middle of box 3 meant that the 3 in box one had to be in row 3. He forgot that there was an open space next to that 69 domino.
Raised an eyebrow a little bit when he colored an orange shape in blue. I just used 4 colors, blue/green for blue and red/orange for orange. It was enough to avoid two shapes of the same color touching.
I got stuck for so long on this because I completely missed that the middle piece had 5 segments instead of 4. I honestly think that's a bit of a flaw in the puzzle design. The I piece is so iconic in Tetris that it's hard not to see it like that.
i’d love to see a puzzle where most of the solving logic revolved around the puzzle having a unique solution - where you have to solve the puzzle by eliminating the possibilities that would give multiple solutions (like avoiding the 78 deadly pattern)
regarding highlighting cages, we can do boundaries with pen tool, and may be such a feature be added to the software to highlight cell boundaries by selecting the cells
49:45 interesting sudoku deciding the row three 3s needed to be in box 1. Let’s see if that comes back to bite. Edit: lucky Simon didn’t trust his own pencil marks 😂
I spent over an hour on this one and eventually gave up and started watching the video. Only after Simon pointed it out did I realize that's actually a 5 line in box 2, which let me get further. It still took me a while to solve it after that, but I did manage to.
Quite pleased with myself placing the 2x2 cage much faster than Simon but I struggled with the 4 cell cage in box 3 something fierce! I think I was too tired to focus on this one properly. I'm going to have to start taking better care of myself so I can play sudoku!
48:15 "If this is obvious, I can't see it at all..." with the 12-pair in column nine forcing a 1 or 2 into r1c7. Proving that the blue 15-cage in box three must be in r1c8 and r1c9 as anticipated by the puzzle having a unique solve. I'm sure Simon will figure out a genius and complex roundabout path to the same conclusion.
I'm only two minutes into my solve, but "tetris" pieces are only 4 cells large and these are 2-5 cells in size. 😰 53:01, started off kinda quick, spun my wheels for like 20 minutes in the middle, ended quickly.
I sort of found the 8-9 pair in column 1 in box 4 a bit sooner based off the math of the box. The tetris block is 100% contained within the box, and accounts for four cells and 15 of the 45 total sum of the box. Two of the cells belong to another 15, minus the value that sticks out into R6C4. That puts the value of the remaining three cells of box 4 to be at least 19, with one cell (R6C1) being a 1 or 2. That not only gives you that 2, but the 8-9 pair that must go in column 1.
I had a rough time with this at first because I misread the rule to say that the shapes *can* be rotated or flipped. Had to watch Simon read the rules to realize my mistake. That made things much more tractable...
73:28. Oh the difficulty was off the charts for me. For how quickly I determined the cage values, I was thinking it'd be easier. Positions of many cages were not too difficult but others took me time to figure (for example) that cage cannot have a 9 but if I put it there there will be a 9. But took me a while to figure out a 9 must go in the cage if it was there. On the other hand, the 789 cage I had set and placed the 9 in seconds. I think the wide range of difficulty amongst the cages was more awe-inspiring that the difficulty of the difficult cages. 8.5/10
I actually managed to solve this one, which marks the first time I've solved a puzzle whose video was over an hour! I suppose Simon was a bit slow today, but still quite happy I managed to do it (though it took me about 80 minutes)
Great solve and great puzzle. Using different colours for the pieces made things very difficult to follow for me (colour blind). For my solve I just used two colours that looked similar to the ominoes themselves. No value at all in using multiple colours if you're outlining them with the pen anyway.
I found this one to be quite a challenge, but definitely fun! My time was an even 1:08:00, solver number 3993. And at 1:02:50 in the video, I'm sure I'm not the only one who wanted to sing "5309", right?
Finished in 59:40. I got most of the Tetris done pretty quickly, but then my mind somehow flipped one Tetris symbol to the other color and I got into a bad place. It got so bad, I had to completely restart the entire thing and I finished it up in 15 minutes with the previous foreknowledge. Fun puzzle but keep your colors straight!
I would never attempt one of these puzzles. I just can’t wrap my mind around how to start. But I always feel so smart when I spot something before Simon, like the 7-8 in box 5. 😂 I also didn’t understand the 3 pencil marks in box 1, which he did “by sudoku” from the 3 in box 3. I couldn’t understand why they couldn’t have been in r1 of box 1. Neither could Simon, apparently, when he went back to them 🤣
OH, if this happens to anybody, check in gear/cog icon, and make sure "hide background image" is off. I had it on for some reason. TURN THAT OFF, though. You're welcome..
46:56 is it fair to ask, where is the _other_ number of the 12 pair in column 7? It must be in row 1. 50:33 Oh. Seems that was the key. Yay, I saw _something_ 🎉
Lol, Simon we see you get plastered during each live stream and they only finish at midnight. You drinking till 2AM ... im surprised you still remembered the nights events!
60:56 Intriguing puzzle. Enjoyed the way some direct geometry worked for placing the -ominoes, but then the numbers became necessary later to push things to conclusion.
@@siron-bq3mv you might be confused, because you let your browser just execute any script. I do not, and I think it is a bad Idea to do so. generally i forbid my browser to execute scripts unless I give explicit permission. This one Sudoku used a different script and I did not realized it does so.
I think there is a problem in mobile version of the link. I am unable to see any shapes on the grid. I tried toggling the setting "Hide background images" but nothing changed.
Not specific to mobile, as it works just fine on my iPhone. However, I have the same issue as you in my laptop. Must be something in the computer/mobile settings that is preventing the images entirely.
For those of us who struggle with colors: how many different colors are there? I think two, but I’m not confident. (I have not watched the video because I’d like to try the puzzle.)
I suppose, if the setter of a puzzle had a specific solution path in mind that _didn't_ require you to avoid creating a deadly pattern in the grid, they would have included something for you to discover that would make that deadly pattern impossible anyway -- as long as you do not short-circuit it, so that by the time you solve the digit somewhere in the puzzle that rules out the deadly pattern, it's too late because you've already assumed the consequences of filling it in. I bet it's possible to set a puzzle deliberately such the _only_ way to solve it is actually to avoid creating a deadly pattern, though ......
I solved such a puzzle a while ago, somewhere on the CtC Discord server. Messes with your head, you needed to make deductions and place pencil marks to avoid such deadly patterns.
They featured a puzzle a couple of years ago where it was supposedly only human solvable by using uniqueness. A computer had been used to prove it only had one solution. It was in a CtC video with the title "What is Uniqueness?". I'll attempt to post a link in a comment below this one. (Sometimes these comments stay, sometimes RUclips deletes them.)
When ur eye sight sees 4*1 not 5*1 ...also is there a rule that says the tile piece must include the cell it's in???..Ie can the 5*1 be shifted 1- or 1+
@@RichSmith77 ah my first read , the "Tetris shape" was referring to to the killer cage or the DD outline/shape. Which further confused the killer cage w/I killercage so,I took to mean the shape must be included in the box which nixeed the 5x1.
They also featured a puzzle called Hydra a couple of years ago that, while having a unique sudoku grid, allowed one of the required snakes to take one of two paths.
Thank you for the feature Simon! This was a very pleasant surprise and a great solve as usual. This puzzle was inspired by the tetris themed puzzles in the game "The Witness". Thanks to everyone who recommended this and I am glad you enjoyed the puzzle
I thought you'd have to put the pieces in with one missing cell in each row so you don't clear a line
I'm so glad the Witness is getting another appearance in one of Simon's solves!
How do you pronounce your name?
@@rixbasesy-ron is how I pronounce it but anything works 😅
for improved clarity next time: you could have used various blue colours for ALL blue tetris shapes, and various brown/orange for the others, re-using the same shade if necessary for shapes far apart. would make the overview much neater and clearer.
Or used the x/o feature of the pen tool to put in blue and orange X's
I wish Simon would remove the colours from cages that have been determined, since there's no need for them any more. So often he ties himself up in knots trying to find a new colour when he could re-use an old one that isn't doing anything useful any more!

Very true
There's still the problem that shading somewhat obscures the glyphs. It would be better if the glyphs could be layered above the shading.
I'm amazed that Simon managed to not mistake a cage for the wrong cage color despite his random coloring scheme.
Not coloring the cages blue and orange is completely nutters.
27:00 Simon forgets the two-piece cage (already proved to be 78) in the top right box. If the top of the T shape occupied R1C7, it could not be 7 or 8 (nor can it be 9). So this T cage contains only one 'high' digit, the three others are at most 456 and the maximum total would be 4+5+6+8 = 23, so that actually disproves the possibility of the T shape touching the top row.
While Simon would kick my butt at this puzzle regardless, this video DOES make me feel a little better regarding my spatial reasoning
Not me yelling at Simon through the screen "it's not 7 or 8, it's not 7 or 8!!!"

Not only that, but he misread corner markings as centre markings.
How is this "with a twist"? There are no rotations allowed :)
In Tetris, you need to rotate or twist the shapes. Here you cannot.
The twist is that there is no twisting.

Using 1:02:37 as a reference (although as mentioned I got there much earlier).
Box 7 has 3 cells of a green 24-cage taking up a total of 22. (Simon is about to mark them as a 679 triple.)
I hadn't yet placed the 2, but as you'll see, that's not needed.
The 35 pair in box 8 is also important.
Now when considering the placement of the size 15 cage in box 7. It's either:
(1) entirely in the box, leaving 45-22-15=8 for the last 2 cells.
(2) or it has 3 cells in box 7, and 1 overlapping a 35 in r9c4.
But in case (2), the 35:
- Can't repeat in the cage, sees the bottom row, and doesn't match anything in the top row of the box.
- So that only location for the 35 in box 7 is r8c1
- So, despite the cage not being entirely in box 7, we know the 4-cells r8c1-3 and r9c3 sum to 15.
- So, we are still left with the last 2 cells totalling 45-22-15=8.
The only difference is the location of those cells.
Either (1) r8c3, r9c1 or (2) r9c1-2.
And can usually be achieved by 1+7, 2+6, or 3+5.
But the first 2 are unavailable due to the 679-triple in the 24-cage.
And now if we were to place the 3+5 in (2) r9c1-2, it would break r9c4.
Therefore, we can deduce the cage is entirely in box 7.
Mark the 2 places for the 35 pair.
And trivially set the composition of the cage as: 1248.

Simon trying to figure out whether green or purple better communicates the cage domes to blue.
Me: Maybe blue?
At 54:57 there was a wonderful opportunity to use the "secret" to resolve the 12 pairs and fill in all the light green 12 digits with their actual value.
In box 4, there is a 4-cell, size 15 cage entirely within the box.
The bottom row has: a 1 or 2; and a 6 with a 4 or 5.
Maximising, we get 15+6+5+2=28.
Leaving 45-28=17 for the remaining 2 squares.
The 89 pair wouldn't be able to go in column 3 due to the existing 78 pair in box 1.
Which resolves:
- the position of the 89 pair,
- a 2 and 56 pair in the bottom row of the box (differentiating the 12 pairs throughout the grid)
- and the cage placed in the top right corner with a 1347 quadruple.
Loved this! Really delightful mix of arithmetic logic and geometry logic. Lovely having all the clues be pictorial too. Great stuff 🎉

Yeah he finally goes back to it at 56:20, but definitely would’ve sped things up if he had noticed that right away.
Fabulous and lovely solving from you Simon!! Fun with the tetris shapes! Great debut Siron123!!
At 49:40 "Okay, three is in one of those two squares by sudoku in row three. That's almost certainly not we're meant to do next."
Yep, because that is a wrong deduction. :D
thank you .. I thought I was going nuts when he did that!! LOL
He saw the pencil marks covering row 1 of that box and assumed that a 3 in the middle of box 3 meant that the 3 in box one had to be in row 3. He forgot that there was an open space next to that 69 domino.
I think Simon is now trolling with his color choices😅
Raised an eyebrow a little bit when he colored an orange shape in blue.
I just used 4 colors, blue/green for blue and red/orange for orange. It was enough to avoid two shapes of the same color touching.
Oh, it looks like another day where Simon gets to use some colors!
To be fair, Simon only uses colors on days that end in Y. 😸
I got stuck for so long on this because I completely missed that the middle piece had 5 segments instead of 4. I honestly think that's a bit of a flaw in the puzzle design. The I piece is so iconic in Tetris that it's hard not to see it like that.
Many of these are not technically tetris shapes, but still a really cool idea!
i’d love to see a puzzle where most of the solving logic revolved around the puzzle having a unique solution - where you have to solve the puzzle by eliminating the possibilities that would give multiple solutions (like avoiding the 78 deadly pattern)
52:17 ... I always enjoy build-your-own-cage sudokus like this
Nice puzzle!
regarding highlighting cages, we can do boundaries with pen tool, and may be such a feature be added to the software to highlight cell boundaries by selecting the cells
49:45 interesting sudoku deciding the row three 3s needed to be in box 1. Let’s see if that comes back to bite.
Edit: lucky Simon didn’t trust his own pencil marks 😂
I spent over an hour on this one and eventually gave up and started watching the video. Only after Simon pointed it out did I realize that's actually a 5 line in box 2, which let me get further.
It still took me a while to solve it after that, but I did manage to.
This red and this green look exactly the same for me. (In boxes 4 and 7)
tetrominos??? oh my i haven’t seen this before
Except for the 3 and 5 length pieces
simon sounds nice in this one! loving the audio quality ( :
58:38, with a loooooooooot of help. Bloody brilliant puzzle though!
Simon in this puzzle you should have removed color when the killer cage was done.
Use blue for blue pieces and orange for the orange ones
The bravest animals in the land are Captain Beaky and his band.
The idea of Simon raucously out on the town until 2am is so funny to me.
Quite pleased with myself placing the 2x2 cage much faster than Simon but I struggled with the 4 cell cage in box 3 something fierce! I think I was too tired to focus on this one properly. I'm going to have to start taking better care of myself so I can play sudoku!
48:15 "If this is obvious, I can't see it at all..." with the 12-pair in column nine forcing a 1 or 2 into r1c7. Proving that the blue 15-cage in box three must be in r1c8 and r1c9 as anticipated by the puzzle having a unique solve. I'm sure Simon will figure out a genius and complex roundabout path to the same conclusion.
!!! What an incredible secret 45! Sudoku continues to amaze me
I'm only two minutes into my solve, but "tetris" pieces are only 4 cells large and these are 2-5 cells in size. 😰
53:01, started off kinda quick, spun my wheels for like 20 minutes in the middle, ended quickly.
Oh that’s annoying ::/
I had the same thought but thoroughly enjoyed the puzzle all the same!
Also, Tetris is a trademark..
I sort of found the 8-9 pair in column 1 in box 4 a bit sooner based off the math of the box. The tetris block is 100% contained within the box, and accounts for four cells and 15 of the 45 total sum of the box. Two of the cells belong to another 15, minus the value that sticks out into R6C4. That puts the value of the remaining three cells of box 4 to be at least 19, with one cell (R6C1) being a 1 or 2. That not only gives you that 2, but the 8-9 pair that must go in column 1.
Mssing line for the grey square - Such a shame :P
I had a rough time with this at first because I misread the rule to say that the shapes *can* be rotated or flipped. Had to watch Simon read the rules to realize my mistake. That made things much more tractable...
73:28. Oh the difficulty was off the charts for me. For how quickly I determined the cage values, I was thinking it'd be easier. Positions of many cages were not too difficult but others took me time to figure (for example) that cage cannot have a 9 but if I put it there there will be a 9. But took me a while to figure out a 9 must go in the cage if it was there. On the other hand, the 789 cage I had set and placed the 9 in seconds. I think the wide range of difficulty amongst the cages was more awe-inspiring that the difficulty of the difficult cages. 8.5/10
Wonderful and exciting puzzle.
mark the high low with colors, and pencil line to mark the shape, it will be easier for solve and watch.
I actually managed to solve this one, which marks the first time I've solved a puzzle whose video was over an hour! I suppose Simon was a bit slow today, but still quite happy I managed to do it (though it took me about 80 minutes)
Great solve and great puzzle. Using different colours for the pieces made things very difficult to follow for me (colour blind). For my solve I just used two colours that looked similar to the ominoes themselves. No value at all in using multiple colours if you're outlining them with the pen anyway.
I found this one to be quite a challenge, but definitely fun! My time was an even 1:08:00, solver number 3993.
And at 1:02:50 in the video, I'm sure I'm not the only one who wanted to sing "5309", right?
13:57 And that’s the way it is!
I cant see the blue under the green. USE BLUE!!!!!
Came here to say the same thing! But Simon must Simon and make colours more complicated than necessary 😂
...and then, later, he starts colouring his 1's and 2's with colours already used for cages. 😂
And then uses blue to fill in an orange shape
Finished in 59:40. I got most of the Tetris done pretty quickly, but then my mind somehow flipped one Tetris symbol to the other color and I got into a bad place. It got so bad, I had to completely restart the entire thing and I finished it up in 15 minutes with the previous foreknowledge.
Fun puzzle but keep your colors straight!
It bothers me more than it should that many of the tetris shapes aren't four cells big.
24:14 nice
1:04:58 double nice
Gosh, sounds like people were talking to Simon at a party.
I would never attempt one of these puzzles. I just can’t wrap my mind around how to start. But I always feel so smart when I spot something before Simon, like the 7-8 in box 5. 😂
I also didn’t understand the 3 pencil marks in box 1, which he did “by sudoku” from the 3 in box 3. I couldn’t understand why they couldn’t have been in r1 of box 1. Neither could Simon, apparently, when he went back to them 🤣
I think he scanned row 3 and just missed that 3 was an option in r3c5.
I colored the shapes orange or blue which helped when I colored the 12 pairs
Very nice! 58' for me🎉
yeah this definitely felt like just above a 3 star, maybe 3.5 - I got stumped a few times
You forgot immediately the 7/8 yellow pair in box 1 to fix the block in box 4 , BY Sudoku 😂
There are no Tetris pieces in the puzzle link.
Blank grid, folks.
(Use it for something if you want)
No Tetris pieces in the puzzle, though.
OH, if this happens to anybody, check in gear/cog icon, and make sure "hide background image" is off.
I had it on for some reason.
TURN THAT OFF, though.
You're welcome..
In the end 7 of the 9 blue cages were blueish, and 2 out of 6 orange cages were orange, so not bad :)
46:56 is it fair to ask, where is the _other_ number of the 12 pair in column 7? It must be in row 1.
50:33 Oh. Seems that was the key. Yay, I saw _something_ 🎉
Lol, Simon we see you get plastered during each live stream and they only finish at midnight. You drinking till 2AM ... im surprised you still remembered the nights events!
Nice one, and think I had the edge over Simon on this one as sadly I was stone cold sober while solving.
Petition to change the blue on the first page of colors to the lighter shade on the second page, I can't see the blue numbers with the dark blue on it
60:56
Intriguing puzzle. Enjoyed the way some direct geometry worked for placing the -ominoes, but then the numbers became necessary later to push things to conclusion.
Oh my the choice of colors is driving me crazy to watch. Why not just use blue and orange?
8/14 aren’t tetrominos but the puzzle is great so I’ll overlook it
44:13. Great puzzle!
Simon needs to use brown more often.
Is this also solvable as a The Witness puzzle?
has anyone else the problem, that the Tetris shapes are not shown?
You might have the “hide background image” setting turned on in sudokupad
@@siron-bq3mv i even tried switcheing it on and off again
@@MusikCassette Hmm I am not sure then. Are you on mobile?
@@siron-bq3mv you might be confused, because you let your browser just execute any script. I do not, and I think it is a bad Idea to do so.
generally i forbid my browser to execute scripts unless I give explicit permission. This one Sudoku used a different script and I did not realized it does so.
Is anyone finding the puzzle broken when imported into sudokupad?
Check if the ‘hide background image, setting is turned off in sudokupad
@@siron-bq3mv I did. It wasn't the issue :/
I think there is a problem in mobile version of the link. I am unable to see any shapes on the grid. I tried toggling the setting "Hide background images" but nothing changed.
Not specific to mobile, as it works just fine on my iPhone. However, I have the same issue as you in my laptop. Must be something in the computer/mobile settings that is preventing the images entirely.
That's 3 in the corner 🗣🗣🗣🎉
34:23 for me. A lovely puzzle, that used both the shapes and killer cages to great effect. Really enjoyed it. Needed it too, after a stressful day.
Well I got one digit, then spent half an hour not doing much else😂 very cool puzzle nonetheless!
I think using only two colours is enough., otherwise one won’t see the color of the tetris cell clearly.
For those of us who struggle with colors: how many different colors are there? I think two, but I’m not confident. (I have not watched the video because I’d like to try the puzzle.)
Probably too late, but it's two, in case you're still hoping for an answer.
I suppose, if the setter of a puzzle had a specific solution path in mind that _didn't_ require you to avoid creating a deadly pattern in the grid, they would have included something for you to discover that would make that deadly pattern impossible anyway -- as long as you do not short-circuit it, so that by the time you solve the digit somewhere in the puzzle that rules out the deadly pattern, it's too late because you've already assumed the consequences of filling it in.
I bet it's possible to set a puzzle deliberately such the _only_ way to solve it is actually to avoid creating a deadly pattern, though ......
I solved such a puzzle a while ago, somewhere on the CtC Discord server. Messes with your head, you needed to make deductions and place pencil marks to avoid such deadly patterns.
They featured a puzzle a couple of years ago where it was supposedly only human solvable by using uniqueness. A computer had been used to prove it only had one solution. It was in a CtC video with the title "What is Uniqueness?". I'll attempt to post a link in a comment below this one. (Sometimes these comments stay, sometimes RUclips deletes them.)
...and it got deleted.
Search for the title and you should find it.
There's only 6 tetris pieces actually.
L J S Z I O T that's 7
@@MelHK_ in the puzzle...
26:45 Now the 78 piece is broken
lovely puzzle, but I'm bothered that many of the shapes are not tetrominos
26:01 for me. Very nice puzzle!
When ur eye sight sees 4*1 not 5*1
...also is there a rule that says the tile piece must include the cell it's in???..Ie can the 5*1 be shifted 1- or 1+
Yes.
"And the Tetris shape must be inside of its corresponding (killer) cage."
@@RichSmith77 ah my first read , the "Tetris shape" was referring to to the killer cage or the DD outline/shape.
Which further confused the killer cage w/I killercage so,I took to mean the shape must be included in the box which nixeed the 5x1.
technically the Schrodinger sudoku was a "published puzzle with 2 solutions". busted!
Common misconception, it actually has one solution that is a superposition of the two normal solutions.
They also featured a puzzle called Hydra a couple of years ago that, while having a unique sudoku grid, allowed one of the required snakes to take one of two paths.
ngl simon calling the Z piece an S piece kinda triggered me but its fine ill get over it
Link takes me to an empty grid
In the settings (cog icon) turn “Hide Background Image” off.
(tetris pieces have FOUR squares. tetra. it's in the name)
Finished in 36:51 by following along with the video.
CTC x CTWC ?!?!
The witness, too witty
