[@zKatari]

for the 10 10 10 riddle, you said that this was an "equation" which isn't ever meant to be in time notation. This would be technically correct if you had said both sides aren't equal and kept it vague but the fact that you said it's an equation makes it so that we should rule out the stuff that isn't exactly math-related. I think you tried a little too hard to misdirect people into thinking it should be math-related and ended up compromising the nature of the riddle.

[@Wildcat2017]

Let's just assume we someone hadn't ruled out time. Its still incorrect as 9.50 is not time notation, it would be 9:50. So 9.50 is, for all intents and purposes, 9 and 50/100, and 50/100 of an hour is 30 minutes, making 9.50=9:30. Which is not ten to ten

The 2nd one would only work if the cup is a perfect cylinder. If the base is larger or smaller in diameter than the top of the cup, then it won't work. Also, 9:50 is not 9.50. If you wrote it as a real number, it would be 9.83333333333....

[@windsanluispotosi]

Correct!! Omar, you should elaborate a more precise language explaining your puzzles.

[@Chyrnobyl66]

for the first one, you could just deal the cards (starting anywhere) into new piles in front of each player, ...no matter where the last card ends up, you just rotate the piles around until the last card goes to you, and everyone should have the correct cards

"Equation Riddle" : Draw a line through entire thing. If that isn't good enough, it didn't say you couldn't erase: then erase portions so that what is left of line makes + of 1 of 1st 10 thru 0 of 1st 10 to make it 8, make + of 1 of 2nd 10 leave 0 alone, make such a short piece left o=before 3rd 10 so that it becomes .10 (binary 2^-1 = .5 decimal) and between the 9 and .5 on the right side leave a minus so the EQUATION becomes +8+0.10 = 9-.50 or 8.5 = 8.5 : )

[@AccordGG1]

[@yavuzsensei6458]

2nd riddle have to give this information: "Glass is cylindirical"

[@marco_robert]

Another solution for Riddle 2: Mark the water level. Cover glass from above and then hold it upright. If the level now is low from the recent one, it is less the half and vice versa... Isn't it right?

[@johnnytmcq]

No. If the glass is conical, the top would be wider. So, when you flip it, the water fills in a larger diameter space, which causes the perceived "height" to go down.

[@varisgupta]

@@johnnytmcq Actually, even if it's conical, this method would perfectly identify if it's less or more than half. A cup that is exactly half filled will occupy 50% of available volume, not available height. The top 50% and bottom 50% by definition have the same volume, irrespective of shape or tapering. Tapering only affects how high along the cup's vertical height the 50% mark would be.

[@uwose]

@@varisgupta so this is the more versatile solution!

[@dimitristripakis7364]

Another solution for puzzle 1 = (We assume he remembers the player he started to deal) Let's say the players are 1, 2, 3, 4 and he started from 1. After the phone call he should start dealing from player 4 and deal all the cards. If the cards run out on 4, nothing needs to be done. If he ends up in any other player, move one card from 1 to 3. It is easy to understand why if you draw it in a Paint program.

[@tashkiira7838]

Puzzle 2: FAIL. Most glasses have an internal taper on the inside, making the top bigger than the bottom. Puzzle 3: FAIL. Time requires a second dot above the decimal point (a colon). Just because a puzzle is famous doesn't mean it has a correct solution.

[@젭젭-z7n]

Didnt get last question as 9.50 is 9:30 for time(0.5 means half and 1 hour is 60min so 60×1/2 should be 30?)

[@Wildcat2017]

For the last one, 9.50 is not standard time notation. It would be 9:50. 9.50 is the same as 9.5, or half passed 9, or 9:30, which is not 9:50

[@dhruboadib3263]

Different solution to the first one: Give a person 13 cards then take whatever you gave earlier. Then keep repeating it

[@briceledain238]

For the second, mark the level of water with our thumb and cover the glass with the other hand. Reverse "upside down", compare the new level with the last one. It work with non cylindric glass.

[@jerdal6825]

It will not. For the same reason it won't work with the tilt method.

[@V7B817]

Puzzle 1 my approach - Just distribute the remaining cards and u can easily tell the one person whom the dealer distributed the last card( by counting the no. of cards in last distribution) 2 - Invert the glass ( I assumed that there is something to completely block the flow of water)

[@stephenfurlong4230]

Conversely the dealer could just take all cards back and deal again.

[@TheRMeerkerk]

1) It is common that the dealer starts dealing from the person left of them and then go clockwise, so the dealer should then just start dealing himself and go anti clockwise.

[@TheRMeerkerk]

Okay starting bottom of the deck is a nice detail that I didn't think of

[@TheRMeerkerk]

2) Tip the glas until it almost spills. If the water still touches the bottom of the glass completely, then it's more than half full. If the water only touches part of the bottom of the glass, then it is less than half full.

[@TheRMeerkerk]

3) 10 10 10 ≠ 9.50

[@TheRMeerkerk]

"≠ is not a clever solution", ugh but the actual solution is so... bleh.

[@jonahansen]

The first one is actually a cool puzzle with a neat solution. But the second one is sort of neat, but it can't be done within the constraint of "no measuring devices", because otherwise you can't know anything about the water level. You cheated on the 10 10 10 riddle. 10 to 10 is 9:50 while 9.50 is 9 and a half, or 30 to 10.

[@JamesWanders]

"In a game with 4 players, the dealer is the last one to receive a card"... Isn't that true for any number of players?

[@miketzan3298]

In order for the dealer to be the last player to receive a card, the number of cards must be divided exactly by the number of players.

[@nightfox6738]

9.5 would be 9:30 not 9:50. ':' != '.' That's not how time works and that solution is invalid. So regardless of whether putting a slash through the equals sign is "clever" or not, its the only valid solution.

[@goguhu]

10 to 10 = 10,000,000,000 ... 9:50 is a clock, 9.50 is a decimal, so 9 thirty (this is even worse than the not-equal way).

[@N8570E]

1. Restart dealing with the last one and rotate backwards for the others. 2. Tilt the glass and look at how the surface of the water meets or doesn't meet the bottom of the glass. 3. No idea?

[@Eismensch386]

While i like some of your puzzles this one was pretty bad. Riddle 1: You have to assume that the last card is given to the dealer. There is no universal law or rule that it must happen exactly this way. Riddle 2: Your solution only works with a perfect cylinder shaped water glass. None of my glases at home have this shape and i probably neven seen one in a perfect cylindric shape. Most have cylindric shaped glasses do not have an exact 90° angle inside... Riddle 3: 9,5 is NOT a way to display time in any system i know. It could probably show the amount of hours or minutes, but than it would mean 9h30m... While those riddles can be fun, they have nothing to do with pure logic.

[@sandeepnaik6818]

10 10 10 puzzle can also be solved by cutting off equal to sign

[@thomasharding1838]

#2 If the glass has a concave bottom, like most do, that will throw off the guess.

[@adityakuricheti6653]

In the third puzzle Y cant we place the straight line in equal to (=) to make it does not equal to

[@LOGICALLYYOURS]

Hey Aditya.... yes you could do it... but that is not logical way of solving. If there is no possible way to make an equation correct, then you can probably think of making the equal sign as unequal :)

[@adityakuricheti6653]

So it is also one answer

[@zenpool5918]

Yes. The third puzzle is stupid and contrived

[@rem7751]

Making a '≠' sign is way more accurate and logical than adding a bar on top a numeral 1; and then magically changing the number zero to a letter 'O'. I was enjoying your videos until i saw this one. It's a stinker.

[@Name-js5uq]

@Benjamin Maisonet correct, the only true answer would be 9:50 not 9.5 as in the video.

[@darrylbatchem8985]

Identify whether a glass is more or less half filled without using a measuring tool. Immediately uses a measuring tool. And 10 to 10 is 9:50 not 9.50.

[@pranavg000]

The answer for the third one could be that 1010.10 is binary form of 9.50

[@shyamsharma1746]

In binary it is 10.2

[@medexamtoolscom]

Um. No. To both of you. Binary of 9.5 would be 1001.1, not 1010.1. 10.5 would be 1010.10. As for shyam sharma, .2 or 1/5, expressed in binary, is .0011001100110011...

Puzzle 1: if first player to receive the first card and direction of next card is known, deal the remaining cards to the last of the first cards and in reverse direction. Waiting/watching to see if I'm right... 0:50 I was right! Didn't know the order of received cards mattered - or I would have added "from the bottom of the deck"...

[@MrMousley]

I managed to work out #1 by myself As you say the dealer always gets the last card, so if he deals the rest of the deck, in reverse, starting with him, then eveyone will get 13 cards AND if he deals from the bottom they will all get the same cards that they would have got. I've seen #2 and #3 before and so I was expecting all the comments like .. ''the glass has to be a perfect cylinder'' .. and .. ''9.50 is not the same as 9:50''.

I would say the script for dealing to 4 people is very clear. (with 5 people for example it would still be possible but you have to figure out where the script ends, which person gets the last card) And the given solution is kinda starting back from the end (the very end) of the dealing process and dealing backwards like you would run a video backwards, and it will end when it reaches the breaking point caused by the phone call interruption. By dealing from the bottom of the deck, you make sure people get the cards they were supposed to get.
