The Aquarium Puzzle: A Hidden Gem From The World Cup

[@jkid1134]

I CAN’T believe you didn’t use blue for the water :P

[@petemagnuson7357]

I think red/green is the usual shaded/unshaded code that he uses, to be fair.

[@JPgreekgaming]

Who needs water when you can have red wine! ;)

[@WilliamRiley-UncleWill]

@@petemagnuson7357 Given that Red/Green is the most common form of colour blindness it might be worth reconsidering that choice. With 50k subscribers stats suggest that over 2000 and up to as many as 3 or 4 depending on racial and gender mix (Caucasian Males can be over 10%) subscribers have some form of colour blindness.

[@ragnkja]

@@WilliamRiley-UncleWill Blue and red or yellow would probably be better. (It would also fix Simon's problems with telling pink and violet apart.)

[@Kavukamari]

it's lava :)

[@ravenous478]

The advice you received about the thumbnails was really taken to heart! I’m loving the new thumbnails, the splash of colour and the face we all love really make the video even more clickable than it was before! Well done :)

[@Sianistic]

It annoyed me surprisingly lot that he called it Aquarium and kept referring the shaded squares as water, yet didn't pick blue but rather red

[@Kurgosh1]

Perhaps the British fill their aquariums with blood?

Lava aquarium

[@d4r4butler74]

Yes please more! I have learned more about puzzles in the few months since this channel came up in my recommended list than I have in decades.

[@Oblivion776]

I love how themey this puzzle type is. It just _feels nice._ Also, as an aesthetic suggestion, I much prefer blue/gold for in/out.

[@ragnkja]

I agree. It's also less likely to be problematic for colour-blind people.

[@AlphishCreature]

I used blue/gold combination as well. Blue for obvious reasons, and gold because it reminds me of the desert, which is the kind of place where water is not.

[@o2g1337]

Amazing puzzle. I also have never seen this before. Would love to see some more of this kind.

[@alxsch]

Kinda late but www.puzzle-aquarium.com/

[@12tone]

Very nice puzzle! I got lost a bit 'cause I misapplied the rules, but once I figured out what I'd done wrong it wasn't _too_ hard to solve.

[@TheNick1704]

12tone It's cool to see that you're also a puzzle fan :D

I wish I saw the world through your eyes. It's so fun watching you constantly in awe. When somebody as talented as you calls someone a genius, you KNOW its true. I've been watching your channel for a few months now and I decided to try the puzzle for once before I watched and finished in 9:28. Keep posting informative and inspiring videos!!

[@GaryBdumR]

anybody knows where i can find more of those puzzles?

[@jacobcoleman4046]

love these different puzzels from time to time, even if im no good at them

[@freddiehand6551]

Jacob Coleman the fun in solving unfamiliar puzzles is discovering strategies by yourself! You’re not expected to be any good at them if you’ve never done any before, but you should not let this discourage you from giving the puzzle a serious attempt!

[@NIMPAK1]

it took me 28 minutes... ...to realize I messed up.

[@StampeSkovgaard]

lovely puzzle, really fun! I used blue for the water, it seemed like the right thing to do.

[@EledierB]

Really fun to do. 16:30 for me. Once I figured out rows 5, 6, and 7 were all reliant on the same 2 blocks, it really opened it up

[@freddiehand6551]

Nice puzzle! Managed 2:58 on computer, fairly pleased with myself! The key with aquarium puzzles is generally to look at the rows, since in any shape, a row has to either be entirely shaded or entirely unshaded. They're quite simple to solve once you familiarise yourself with the logic (and if you get stuck, it's very easy to do a quick bifurcation).

[@freddiehand6551]

BTW, please do upload Hideaki's solve of the Japanese Sums! It was mindbogglingly quick: I'm fairly certain that Ken Endo and Kota Morinishi were only halfway through the puzzle when he finished. Helps to be a kakuro and killer sudoku master, I suppose.

[@beansock]

i started with the 7 row, there's three 3s so the 1 must be picked with two of the threes! that gives the row below as well

[@Sianistic]

4 minutes sharp ... been doing these kinds of puzzles before (under the name Pouring Water) , and as soon as you get the hang of them, they're actually surprisingly easy to handle

[@joshualifeheart3671]

Saw this puzzle, read the rules, had to try it. Took about 10 minutes to solve for me. Relatively fast. Hope to see more like this sometime soon.

[@hatterson]

I haven't seen this type before so I had to watch your first two steps to start understanding the logic, but once you did the step on the 5 in row 3 it made sense and I could see how to attack the rest of it. Would love to see more of these, especially if they're a bit larger too.

[@57thorns]

A nice eleven minute solve. Fairly easy once I got into the water thinking and how the green and red (I used blue for water) tiles spread.

[@twalton]

That was very satisfying to watch. I also felt like the red should have been blue, haha. Blue would have been helpful for viewers with red-green colorblindness as well.

[@jrtomsic]

about 32 mins for me. I was able to start it myself pretty well but I got stuck and needed a hint that I could color the middle section of the 7 row. After that, it all fell into place for me. Really fun puzzle!

[@AmaranthRBY]

Only took me 6 minutes and 17 seconds, absolutely delighted with myself haha. Hope to see more of these in the future because I'm apparently really good at them

[@andrewgrant6516]

Brilliant! More like this, please!

[@RickyCruzMedia]

Very fun puzzle! I wonder if the fish I saw in the empty squares to the right was an intended part of the solution, or if I was just seeing things. Enjoyed this one.

[@BlueCyann]

That was fun. Took me a few tries, I kept confusing myself with the rules (not the fault of how they were written, just my memory), then made one legit mistake somewhere that had me unwinding almost all the way again, but I finally got it. For anyone who struggles at first because of unfamiliarity, keep trying! It's totally do-able.

[@Griffsterometer]

14:00! Not bad for a drowsy, late-night solve :P I haven't got the hang of the sudokus on this channel yet but I can do the more unusual puzzles haha

[@YoshiFawful64]

Did this one in 12:30! Pretty fun and interesting puzzle type, would like to see more of it.

[@Silvergrooves42]

6 and a half minutes. I had seen this puzzle type once before but never tried because the explanation of the rules was super confusing, but it was a nice and simple here. My main method of solving was using math to figure out which combination of blocks a row or column could use, since it's always the entire row if it's filled, (and columns always fill downwards), which made it very restrictive

[@Silvergrooves42]

I'm super happy to say that the solver at the end also started with the exact same 3 deductions that I started with

[@StevenJacks]

This puzzle was so satisfying. Please share more of these if you find them. : )

[@akaigetsu]

I would love to get more of these aquarium puzzles they're are my favorite so far.

[@danielles3841]

4:52, once I figured out the rules. I love aquarium puzzles

[@ericwallhagen3146]

Took me a while to note the full significance of the 7 clue, and the effect on the two clues below, but once I had that "aha" moment, it all fell into place. (no pun intended.) Loved this puzzle, would love to see more of them.

[@thomasdalton1508]

A new puzzle type for me. I like it! Took me 15:43 to solve. You used red and green the other way round than I did which made watching your solve very confusing!

[@jakewhitttyyy]

13:10; I hadn't seen one of these puzzles, but the rules are very intuitive. Went nicely with breakfast~ Cheers for helping me get better with puzzles!

[@LorisLaboratory]

Got this in around 16 minutes. Started with the bottom row and mostly worked my way up as that seemed to make sense in a 'gravity' puzzle, but other than that I can't really explain or understand how I solved it. I just...did, on some intuitive level. Intriguing! Would enjoy something like this again. :) Not using blue for the "water" in the aquarium is one thing, but it always cracks me up and confuses me that in these vids red is used for "right" and green for "wrong/nope cant go here".. XD

[@tonybates6551]

As always, love the variety puzzles! Beautiful new puzzle and I hope somewhere starts to release them more frequently. Simon and Mark, ever consider moving into the publishing business?

[@Anthony-vu8bl]

LOVED the concept, if you find some more, feel free to share them to us !

[@jetseschoffelmeer6706]

You can actually solve this without "underflow". (I accidentally did by misunderstanding the rules) Obviously this would make it slightly more difficult, but it's a fun challenge for those who want to try. The logic goes a bit further. Thanks for sharing all these fun puzzles!

[@jetseschoffelmeer6706]

by underflow I mean forcing cells within the same row to be filled if they are not DIRECTLY connected. (for example it would be possible to fill the W shape like this: O I O O I O I I I I I I I )

[@tatRip]

Love seeing these new type of puzzles for sure.

[@littleschnitzel8226]

Wonderful puzzle! I shaded it blue & orange to make it look more like an aquarium. :) It was quite easy, nevertheless much enjoyable to solve.

[@DarkChasm]

loved it, great puzzle!

[@joelstuckey3685]

I really enjoyed the “trick” of the three regions from row 5 trickling down to rows 6 and 7. In future, can we please see blue for the water? I don’t know why, but this is my main feedback 😆

I'm surprised how well this works. Got it in 16-ish minutes! Too bad the app couldn't check for me, but fortunately it's not hard to just count squares myself. XD

[@jaredwhite4934]

Really nice puzzle! I'd love to have a go at one myself.

[@saaampe7229]

took me 14 minutes. lovely puzzle and great video as always

[@Blancanunca]

17:12, the aquariums seem to have a pretty directed solve

[@XkcdEsperite]

Took me about 12:30 and I'm surprised I was able to solve it so quickly. This is a neat puzzle, although I always find it easy to lose track of where exactly the region borders are. It took me a little bit to realize/remember the W is one region and I could treat the three spokes in row 3 as a single region for logic purposes. That was what really finalized the solve for me. quick edit: I wish I could put custom puzzles into your web app, it's a really convenient way to solve puzzles and it would be nice if I could use it to work on puzzles even if I found them somewhere else.

[@SoniCraft98]

I kept getting off to the wrong start because I thought the all or none rule applied to columns as well! A little frustrating, but a nice puzzle anyway.

[@williedavis9465]

I enjoyed the puzzle and would like it to appear more often on the channel.

[@jimdetry9420]

That was fun. It took me a little while to figure out how to attack it but I ended up doing it the same way as you and the champion did. I don't know if it is true of aquarium puzzles in general, but there seemed to be only one logic chain to solve it.

[@CUBErt_]

That was interesting! Around a 14:10-ish finish, forgot to note the exact time. Took a minute for the rules to click with me but once I understood it went rather smoothly. I'd love to see more like this if you can get your hands on any Also, like some others are saying, the thumbnails look very nice!

[@Escviitash]

Can't believe I missed this video. It was quite easy and took me only 4:25

[@zeeker0315]

Fantastic idea for a puzzle! Would like to see more if you can find any.

[@Bennatte]

Took me 9:40 just after hearing the rules. Quite proud!

[@littleschnitzel8226]

Question for CrackingTheCryptic: I don't seem to get the star-rating system in your sandwich app- is time the only factor, or are there other factors as well? I would really appreciate your word on this, thank you very much in advance. Other than this I really enjoy your app and your other puzzles as well very, very much, so many thanks for that! Keep up the good work in being world-class solvers!

[@tomasxfranco]

Looking at the Tomura solve, at 18:23, I don't get what logic allows him to discard the 2 spots from the second row.

[@Donutkillerpro]

I have been following the channel for some weeks now and I really like the daily puzzle solving. But I just cant solve most the sudokus you do in the videos without a lot of help of you solving it so I was wondering if there were some easier sudokus on the website? I know there are other sources for sudokus but I really love the GUI you have.

[@freddiehand6551]

The channel does have playlists for specific types of sudoku logic, e.g X wings. I don't see a playlist of easy sudoku but I imagine it could be easily created.

Would be nice if their website also had a "blank page" option so you could fill in the starting numbers yourself and play any sudoku.
