Natasha rouge Nateaschea : were the cats dead or alive

n 0 : It's a nice math puzzle but literally has nothing to do with giant cats, so the riddle could've been named anything

Ihatequests Dev : This riddle has nothing to do with cats, they just used cats as the thing you have to save, when it could of been anything.

Darth Dogoz : Boi i woulda just pic the damn lock on the door Super spy my foot

Henry Weng : The answer to the last riddle is 7 steps. You are supposed to solve it by working backwards from 25, as this greatly reduces the number of cases. When working backwards, the operations are either +3 or /2. One can organize these cases like this: Initial: 25 Step 1: 28 Step 2: 14, 31 Step 3: 7, 17, 34 Step 4: 10, 20, 37 Step 5: 5, 13, 23, 40 Step 6: 8, 16, 26, 43 Step 7: 4, 11, 19, 29, 46 Step 7 is the first step where there is an 11, so 7 is the answer.

Gavin : Move over, Bonus Meme. Bonus Riddle is the new most-loved segment of YouTube.

Laura C : 5-12-19-26-31-36-6-11-16-4-2-9-3-10-17-24-29-34-39-44-49-7-14 also works :)

Starby : Also WHY IS EVERYONE NAMED AFTER ANCIENT GREEK LETTERS?!

zat1245 : These are fun because it’s just math and a bit of working backwards. You can only use the root button on perfect squares: 4, 9, 16, 25, 36, 49 but no others because the rest go above 60. We need a 2 to start. Since it’s not possible to add 5 and/or 7 to get to 2, it must have been from the square 4. Same with 4 and 16. We would only be able to get to 16 if we had a six. Well we can make a six with 36. Since 5+7=12, if we do that 3 times we’ll get there. 0 +5, +7, +5, +7, +5, +7, √, +5, +5, √, √ = 2 We can’t just add to get to 10, we need another square. We can’t use 25 because 5 has already been used. So then we use 9. To get there is easy. 2 + 7, √, +7 = 10 Now all that’s left is 14. No adding once again and there’s only one more square: 49. 10 is divisible by 5 and 49 is divisible by 7 so if we reach the common multiple of 35, we switch from +5 to +7. 10 +5, +5, +5, +5, +5, +7, +7, √, +7 = 14 All done. As for the bonus one, we can work backwards too. 25 We couldn’t have gotten to 25 by x2 so the last step must have been -3 Step 1: 28 28 can be gotten from x2 or -3 as with all evens Step 2: 14 or 31 14 produces 2 paths while 31 makes 1 Step 3: 7, 17, or 34 Step 4: 10, 20, 17, or 37 Step 5: 5, 13, 10, 40 We already have had a 10 sooner so that path is obviously wrong Step 6: 8, 16, 20, 43 Step 7: 11, 4, 8, 19, 10, 23, 46 We hit 11 through one path in seven steps. By reversing the pattern, it’s: -3, -3, x2, -3, x2, x2, -3

Anonymous : I figured out the Bonus Meme....I mean riddle first you have to find how to get to 25, and you can only do that by subtracting, since you cannot x2 to get to it. 28 is the nearest one. so you halve it, which gets you 14, then halve it again, to get 7. you may think 7 is impossible to get, but remember we can -3 as well so we go to 10, and halve it to get 5. because of this the path has been laid out. you go 11-3-3x2-3x2x2-3 to get to 25 in 7 moves.

Dipshan Khadka : Cheese has holes More cheese has more holes More holes means less cheese So more cheese is less cheese

NINTENDO MAN : Wait, so are Schrödinger's cats dead and he is bringing them back to life, or are they alive and he is just mutating them with radiation... IDK I guess it's both

Bekah TheDonut : This was sooo easy At least after I watched the answer

StriKerZ : The answer to the first riddle is *literally* shown at 1:10

Jonathan Johnston : My answer: put TNT on the door and blow it up.

Lelouch Yagami : Bonus riddle Answer 7 steps: 11 8 5 10 7 14 28 25

GT_ 810* : Reply/like if u had no idea wtf just happened but just watching for the fun of it

Alto Bluedot : Made an Autoliker for this type of videos!!! :) (In Python, uses web libraries and automatically clicks Like)

W. D. Gaster : just put a c4 on the door

jabsting46 : Bonus riddle answer is 7 -3, -3, x2, -3, x2, x2, -3.

Atheist In Louisiana : This isn't a riddle about cats at all! It's a math problem! I feel cheated. Moar giant cats!

Starby : PLOT TWIST! It’s just a dream and you were having nightmares about riddles.

Carlos Uribe : If I was ever in a situation like the one in these riddles I would die 🙃😑

sia : for the extra riddle: 11 - 3 = 8 - 3 = 5 x 2 = 10 - 3 = 7 x 2 = 14 x 2 = 28 - 3 = 25 so we get the numbers: 8, 5, 10, 7, 14, 28, 25 (11 is the starting number so it doesn't count) so fewest number of moves that it can take is 7

Marty Mcmarty : Course the real question is, are the cats alive?

Justin Y. : Well, for once, we can finally achieve humanity's goal of perfecting genetically engineered catgirls.

NATHANIEL TOMPKINS : All you have to do is enter those numbers, and you’ll be free But there’s a problem

Julia Wburn : For the bonus riddle, you start out with 11, minus 3, which equals 8, then you double it, which equals 16, minus 3, minus 3, and minus 3 again which equals 7, then you double that, which equals 14, and then double that which will give you 28. :)

Alexandra B. : i think the lowest amount of steps could be 11, 8, 5, 10, 20, 40, 37, 34, 31, 28, 25

Timber Blue Wolf : Cats in the box wouldn't grow the box would since the cats are inside the box. And how do you know if the cats are going to attack the city? I am pretty sure that they would just sleep everywhere if somehow they did grow larger.

Saukhya Telge : How many of you couldn't solve the riddle?;)

Alex Halstead : Dr. Schrodinger. Lol I see what you did there

Siddhesh S : I reached all numbers but I got 10 twice. Tough luck! My series was: 5 10 15 22 29 36 6 11 16 4 (2) 9 3 (10) 15 20 25 32 37 44 49 (7)

sunita pandita : 11(-3)8(-3)5(*2)10(-3)7(*2)14(*2)28(-3)25

DarkrarLetsPlay : The long s (ſ) in 0:06 is wrong. ſ and s were not interchangeable and there were strict rules when you had to use ſ and when s.

Billy K : Yeah I can never solve these riddles

Samuel Bridarolli : This riddle blew my mind, Ted-Ed is amazing.

Evodius Okki : Here the bonus riddle 11-3-3=5 5×2-3=7 7×2×2-3=25 So the maximum step is 7 i think

Ashleigh : Yeah but tell thing is now that Ray could have hit a worm or ant. I would rather have a giant cat then ant or worm

Emmanuel Nyavor : So Schrödinger has finally been turned into a villainous, cat-weilding fiend

Gerzen Gamer13 : looks like it's a cat-astrophic riddle 😏

Ross the Boss : I CAN’T BELIEVE I DID IT!!!! When I got all of the numbers together in that order I literally broke out in tears!!!

Marshall R. : For the bonus riddle do 11*2 then 22*2 for 44, then subtract 3 ten times to get 14. Double that for 28, then subtract 3 to get 25. :)

Brendan Risney : Second puzzle solution: 11 -3 = 8 8 - 3 = 5 5 x 2 = 10 10 - 3 = 7 7 x 2 = 14 14 x 2 = 28 28 - 3 = 25 Don't know if that's the shortest, but it's the first I thought of.

Heximy : If agent epsilon can look through the surveillance to find the final outcome then how come he cant look at the sequence that dr Schrodinger put it in .-.

Mi da rock : What if there was an ant on the target...

SamTheCuber 04 : I got the second riddle: 11x2=22 -3 -3= 16x2= 32 -3 -3=26x2= 52 then subtract three till 25

Michael Alexander : this was pretty simple, just time consuming really cant believe it worked 11, 8, 5, 10, 20, 17, 34, 31, 28, 25

Hello Hi : I figured it out in about 2 minutes by using the fact that you can have a negative or positive value... guess you guys were being picky
