I like how you sneakily add the bit in about sigma notation. Sigma is one of those scary math symbols that non-mathematicians tend to assume is way more complex than it actually is.
You're totally right; when I taught it in high school, my students would get intimidated by it pretty much instantly because HOLY MACKREL A GIANT GREEK LETTER (not gonna lie; this might also have been my reaction when I first learned it :) ) I hope this helps alieviate that for people. :)
If the right tiles appear in the right places, then well, zero. Assume, player only moves left and right and that the tiles that appear are always different from what's to the left or right in the row where it appears. We don't see this happen often in practice, since 90% of the new tiles are 2s and it's likely the adjacent tile in that row is also a 2. But given the rules applied in the video, a zero score is possible. More complicated is: What is the lowest possible score if the player always moves in the correct direction to maximize scoring chances, but is just really unlucky? Is it guaranteed that at least one tile combining vertical swipe will always come available?
For those that cannot wait, the answer is 3,932,100. :) Edit: Yes, you need a just-in-time-4 for all the tiles. Explanation below. (tl;dr: pause the video at 3:32 to see the answer) I didn't do a great job of explaining why you need a just-in-time-4 for all of the tiles less than 2^17 on the final board; the animation happens quickly, and I didn't verbalize much. Let me try to remedy that. Consider the 2^16 tile. Previously, you'd been able to make a 2^16-tile with a snake that had two 2-tiles at the end, and was sixteen tiles long. But, when that collapsed into a 2^17-tile, there were only fifteen tiles left! This means that you don't have room for those two 2-tiles when you go to make another 2^16 tile; you need two 4-tiles. You can pause the video at 3:32 to see the board setup. Thing is, when you complete the 2^16 tile, you are now down TWO spaces to make your next snake, meaning you can only make a 2^15 tile -- but it'll still end in two 4-tiles. This pattern continues all the way down to the 8 tile. Hope that helps!
9gag.com/gag/a9MMVyo I did this. I'm guessing the discrepancy is due to the number of times a 4 spawned instead of me creating one out of two 2s. This amounts to 16130 4s, which either means that my hypothesis is wrong, or I should be glad that I still have fingers after all that swiping.
He doesn't have a ton of subs because he's talking about math and not blowing stuff up while making exaggerated faces. People don't tend to want to learn when on TH-cam. They typically try to be slap-stick entertained. I appreciated this tidbit of information and learned what a sigma is and how its useful. Am I ever going to use sigma in my life? Probably not, but it is still something new I learned and I'm sure I'll be seen as a nerd some day for being able to name a Greek symbol.
I just wanted to add this comment because when you read the highest possible score it reminded me of my 5th grade teacher harping on “and” in numerical values. According to my teacher “and” is reserved for the decimal place. I appreciate someone using it for its general use in public instead of the technical purpose. Loved your video and thank you for a breakdown of 2048! 🙏
That's a good question! I probably could have been clearer about that. Yeah, you'd need it for every tile. To see it, consider the 2^17 we made that required 16 tiles to accomodate the 'snake' needed to make it. If you look closely, when I go to make the 2^16 tile, you can see it needed another 'just in time 4', because it had one less free tile on the board (it'd been taken up by the 2^17 tile). It turns out that's a pattern, and every time you try to pack the next highest tile on the board, you need that just-in-time-4. :)
@@TheTaylorSeries Thank you for explaining that. Now I see that you need the just-in-time-4 only the last time you pack the 2^n tile, but you need it for each one.
@@therealEmpyre Every other tile also needs to be a 2, and it takes 2^n-1 tile to make a 2^n tile (then take off 2 to account for the 4 required). We already start with 2 2 tiles so we need 2^2+2^3+2^4+2^5+2^6+2^7+2^8+2^9+2^10+2^11+2^12+2^13+2^14+2^15+2^16-32 2 tiles, which comes to 131036, and 15 4 tiles. Using the percentages shown of getting each tile the odds of getting those tiles in the required order are 0.9^131036*0.1^15. shame no calculator I found online could give me an actual number.
@@darkraidisciple8717 It is even more complicated than that. Not only do you need the right number at the right time, but also at the right place. Usually, there are more than one spot that would work, and there is not a constant number of empty spots. Since I am not a mathematician, I have no idea how to formulize those odds.
I remember a Numberphile video from a few years ago, where various professors and mathematicians were reacting to 2048. Their reactions were mostly along the lines of "It's a silly game, not really my thing, maybe my wife/daughter would like it". Really annoyed me at the time that they seemed to _only_ look at it in terms of "do you like this game", and didn't actually look at the game's _structure._ I mean, Minesweeper has been proven Turing-complete, FFS.
@@TheTaylorSeries If I'm understanding the proof correctly, any given Turing machine program can be converted to (and from) a variant of Minesweeper's rules played on an infinite grid with a specific initial configuration of mines/symbols, such that the given Turing machine will eventually halt _if and only if_ the corresponding pattern of "mines" (or symbols) cannot be extended infinitely under the given variant rules. (Conversely, the source Turing Machine will _never_ halt if the resulting mine pattern _can_ be extended infinitely.) It's an extension of an earlier work which showed that Minesweeper was NP-complete, by using mine configurations to simulate digital logic gates. web.mat.bham.ac.uk/R.W.Kaye/minesw/infmsw.pdf

I agree, this is a great question. :) While the spawn value probability part is probably straightforward to figure out, the spawn location probability part seems a LOT harder!
The Taylor Series It is probably ~1-10%. You calculated by saying that all tiles show up when we need them. Because there is a higher chance of 2 to show up, (90%:10%), and 4 is more used here, it will most likely be less than 5%. Maybe less than one. I’m only grade 6 though, so I can’t do it ;-;
@@317pboqyc2c6oemvkkcwcncckykq nice thinking, but lets consider only the chances of spawning only 2s until he gets a single 2ˆ16 tile. To get 1 2ˆ16 tile you need 2ˆ15 times the tile 2, and the chances of a single 2 tile spawning is 9/10. But since we need it to happen 2ˆ15 times, you have to multiply it by itself 2ˆ15 times: (9/10)ˆ(2ˆ15) and that is so small that my calculator couldn't calculate. But it`s pretty much zero. Hope I helped :D
I remember years ago doing practice mode for months redoing 4s to never appear until I needed them for the maximum tile values. I actually managed to get the maximum score and felt weirdly proud of it.
Very interesting video! Seeing the trouble people seem to have understanding the just-in-time-4 usage, maybe you could do another video on a different 2048 related question explaining this concept more in detail? Great work nontheless!
Yeah, I'm gonna have to do a followup vlog on it. :) I blame myself; I didn't explain it well enough or let the animation stay on the screen long enough. Whoops. Live and learn!
This is the type of content in which I would gladly watch the commercials in its entirety to make sure you get compensated properly. Thanks for making these videos! 🙏 👍
That whole counting->generalizing segment from 4:00 to 6:04 is something I wish I watched before taking my probability class, because that's exactly the kind of thinking it requires. You explain it so well!
I love this question! It's very hard to answer tho. There's two random elements to a tile spawning: the value and the location. If we only consider the value probabilities, we can likely figure this out in a pretty straightforward fashion. The location one, though, seems a LOT harder, and I have no idea how to approach it. :)
@@Xnoob545 I found a website that as you go on, the numbers get higher and higher so like it starts at 2 Thebesthen 4 and 8 and goes higher. I've gotten the 8096 tile before with it. Basically cheating.
The trick of doing a -4 to compensate for the "just-in-time 4" isn't enough to determine the maximum possible score. Taking in consideration that a "4" appears 10% of the time, this means that for all tiles in the board, 10% of the "2"s that compose it are actually "4"s, and those need to be subtracted as well. Unless this was a game where "undo" was allowed, in that case you could always undo the move where a "4" appears, except when you actually need it.
one of our professors had us try to come up with proofs about the win conditions for the take away game nim. There are alot of variations of the game, for example you could only pick up one or two or three, or any number of any size pile or you'd take any number of sticks from just one pile. Win condition would be whoever takes last stick wins or loses. I think this would be a nice game to talk about.
Haven't you heard of it? Check out Nim with 2 piles where you can take any number from either pile or the same from both. It leads to a surprising optimal strategy involving the "spectrums" of phi and its square. The spectrum of a number, k, being the series given by floor(k*n) with n being the positive integers.
Vid quality is too high for only 11k subs. I don't often sub to channels that make me use my brain, but you deserve this. Lets get this handlebar mustache to 100k!
4:00 The tiles are... 2 to the 3rd: 8 2 to the 4th: 16 2 to the 5th: 32 2 to the 6th: 64 2 to the 7th: 128 2 to the 8th: 256 2 to the 9th: 512 2 to the 10th: 1024 2 to the 11th: 2048 2 to the 12th: 4096 2 to the 13th: 8192 2 to the 14th: 16384 2 to the 15th: 32768 2 to the 16th: 65536 2 to the 17th: 131072 More tiles: These are designed for 5x5 and bigger. 2 to the 18th: 262144 2 to the 19th: 524288 2 to the 20th: 1024576
This is pretty much how I play games. I learn about the mechanics and things like damage/defense calculations, then I start solving for theoretical maximums and minimums. I can't tell you what a ball it is to go down this rabbit hole in a games like Warframe or Pokemon. The wikis have most of the formulas, so I luckily don't have to derive those equations usually lol.
Too bad Game Theory rarely does those kinds of videos anymore, and the physics ones (my favorite ones) are usually done by Austin now instead of Mat Pat. Austin’s voice is obnoxiously annoying
I recently did that with AoE 2 and not that long ago with Mario Kart 8. I even have a Mario Kart spreadsheet with kart stats. My friends thought it was way overboard. lol
When I was a kid I loved doing this with Paper Mario! I remember having lots of sheets of paper trying to calculate everything (and probably failing with my terrible kindergarten math skills). Nowadays I don't see this level of nice counting problems. Closest I get is numerical approximation software and programming. Looks like its time to visit AoPS for my fill!
This is actually slightly low! In the early stages of the game, we don't need the "just in time 4" since the board isn't filled up yet, so we can afford to have all 2s spawn. I'm not gonna do the math, but I'm guessing the answer you gave is low by around a hundred or two.
Fk if i knew this before the surprise test on math (this was not taught because the test was designed for people 3 years older than us) I would’ve got even more points.
Woah. Great job! A lot of math explanations assume prior knowledge or just give facts instead of working through them. This video (and your general style) require very little math background, but they still encourage math reasoning-which is exactly the thing that makes math more interesting and less scary. I hope this channel continues to grow-I’ll keep watching!
I had a version of the game that had an undo button. I used that to reach this score. You could only ever undo just the previous step, but the next tile would appear randomly every time.
I used to play this game in my way to school, and sometimes reached some incredible scores. This video made me go back to those days, it was joyful and interesting! keep the good work
There was a version I used to play where you could undo your last move and redo it and repeat. Some of us actually reached that score (It only took weeks of playing and not messing up too bad)
I have just found this channel and after reading the comments I have figured that the channel just bloomed coz most of the comments are just a few days old. Keep doing the good job buddy hoping for some great videos from u in the future
I'm happy that I found your channel. Good production value, great and thorough explanations, awesome voice. Turns out that TH-cam recommendations aren't complete rubbish once in a blue moon :)
BTW, it may be a good example to show some series sums can be computed, first with the geometric series and then using a dummy variable and the derivative (though I don't think you've dealt with derivatives yet). The shorthand answer to this sum comes out as rather compact - > 15*(2^18 - 4)
Calculus is too advanced for most audience... also, you don’t need calculus to reduce it... you only need to times each term by 2 and cross subtract to reduce it into a geometric series...
@@TheTaylorSeries Totally understandable, I meant this as a possible suggestion in case you ever wanted to make videos about the subject of summation of series.
Other questions: *A)* What's the _lowest_ possible winning score? For that you want a cascade of tiles from 1024 to 4. All made from 4s. Drop another 4, then drop 2s and 4s so they don't combine while the cascade collapses. (My best score is 20032; just can't break 20k.) *B)* What's the maximum possible _non_ -winning score? The highest possible set of tiles would be eight 1024s and eight 512s, arranged checkerboard-style. But you can't build up to that, so.... (My best score is 37784.)
I hope you get a lot of subs really quick you deserve it your work is fantastic keep it up! Btw you were correct the Σ (sigma) it's just a capital letter for the Greek letter s
There was a version that allowed for infinite undos. After solid 2 weeks of playing I finally managed to get the biggest combination on screen. I would have probably played twice as long if I was aiming for the maximum score as well.
Found this video, never before seen you, and I love it! You took something that would have taken me a few months to solve, and gotten it simplified where it would take me a few minutes to solve. You are better than most other math TH-camrs, because you make it something that only a Harvard student would understand, turned into something that a grade-school student would understand. Others would just give how they solved it, and give the solution, and that would be it. Not you, though. Thank you for that.
Excel is not required. The sum of powers of 2 (a geometric progression) is just 2^(n+1) - 1. Geometric progression formula is (1 - a^n)/(1 - a). Taking the derivative w.r.t. 'a' can yield a formula for the sum of n*(a^n). Anyhow answer can be arrived from (17*2^19 - 18*2^18) - (2*2^4 - 3*2^3) - 2^18 + 2^3 - (18 - 3)*4 = (17*2 - 19)*(2^18) - (2*2 - 4)*(2^3) - 60 = 15*(2^18) - 60 = 3932100.
You made maths interesting for me with this... But I have finished my school, college, now will get a job in 6 months. But I will study maths for sure.
There are several interesting questions. What is the optimum strategy? ie. what strategy has the highest average score? What is the miminum score? ie. is there a sequence of appearing 2s/4s on specific spots, that no matter how you play, you will loose after at most N steps? What is the longest possible game? ie. assuming you don't want to combine tiles, but also not loose, how long can you play (in terms game steps). What strategy has minimum average score? ie. the most efficient way to loose.
I didn't expect to see a measly ~4.6k subs given how clean and well-done your videos are. You could give folks like Mathologer a run for their money. Good stuff, man! Subbed, and can't wait to see what you do next!

@@sunlakestar2549 IVE BEEN WAITING FOR 4 MONTHS PLZ ANSWER HOW
@@Xnoob545 I found a website that as you go on, the numbers get higher and higher so like it starts at 2 Thebesthen 4 and 8 and goes higher. I've gotten the 8096 tile before with it. Basically cheating.
The trick of doing a -4 to compensate for the "just-in-time 4" isn't enough to determine the maximum possible score. Taking in consideration that a "4" appears 10% of the time, this means that for all tiles in the board, 10% of the "2"s that compose it are actually "4"s, and those need to be subtracted as well. Unless this was a game where "undo" was allowed, in that case you could always undo the move where a "4" appears, except when you actually need it.
one of our professors had us try to come up with proofs about the win conditions for the take away game nim. There are alot of variations of the game, for example you could only pick up one or two or three, or any number of any size pile or you'd take any number of sticks from just one pile. Win condition would be whoever takes last stick wins or loses. I think this would be a nice game to talk about.
Huh! That's kinda cool. I just wikipedia'd Nim. Thanks for bringing that to my attention. :)
Haven't you heard of it? Check out Nim with 2 piles where you can take any number from either pile or the same from both. It leads to a surprising optimal strategy involving the "spectrums" of phi and its square. The spectrum of a number, k, being the series given by floor(k*n) with n being the positive integers.
i didnt know a game as simple as 2048 could be explained in such a technical and mathematical manner
I got a 16384 once, but I got so lucky with my tiles that game
and i did inspext element
Anyone who goes for over a 4k tile knows the game is REALLY RNG based lol
I’ve got the 4096 tile
My best is 65k
I got the 16384 tile with a score of over 240k
I was kind of assuming the maximum score was 2048. But then again I have never heard of 2048 before lol
It's nice knowing TH-cam played for you! Great vids, keep 'em up, and I'm still waiting for the inverse of Tetration!
Someday ... :)
2048: the highest possible score. Einstein: Am I a joke to you?
Vid quality is too high for only 11k subs.
I don't often sub to channels that make me use my brain, but you deserve this.
Lets get this handlebar mustache to 100k!
Played this for a week now. Without ever searching this game on YT, it somehow made it to recommended. Suspicious?
You kind of look like thanos
No, Thanos looks kind of like *me*. :)
1st like
No
You've heard of Thanos, now you've seen Epistemos. Or Logos, I never know.

dude thank you for showing me how amazing math is and what i missed out back in school :D
The reflection of the autocue in his glasses :D Nice Video!
This is pretty much how I play games. I learn about the mechanics and things like damage/defense calculations, then I start solving for theoretical maximums and minimums. I can't tell you what a ball it is to go down this rabbit hole in a games like Warframe or Pokemon. The wikis have most of the formulas, so I luckily don't have to derive those equations usually lol.
Truth. I played Factorio for a while; that one is a very deep rabbit hole.
Too bad Game Theory rarely does those kinds of videos anymore, and the physics ones (my favorite ones) are usually done by Austin now instead of Mat Pat. Austin’s voice is obnoxiously annoying
I recently did that with AoE 2 and not that long ago with Mario Kart 8. I even have a Mario Kart spreadsheet with kart stats. My friends thought it was way overboard. lol
When I was a kid I loved doing this with Paper Mario! I remember having lots of sheets of paper trying to calculate everything (and probably failing with my terrible kindergarten math skills). Nowadays I don't see this level of nice counting problems. Closest I get is numerical approximation software and programming. Looks like its time to visit AoPS for my fill!
r/iamverysmart
So many hours i will never get back... Thanks 2048
you just made math great for me. Thanks!
That moment when you get a higher score by bashing your arrow keys than when you go carefully using your brain
This is most definitely a thing. :)
Subbed before 1M
i seriously thought you had at least 4M subs
You were the best teacher a student could ask for and Aarons sorry he blew you off so much
Btw Taylor TH-cam loves you now xD
Dude: spends a whole week writing formulas and scripts
Me: looks at the scores
6:06
Mental buffering
*the entire video*
Mental buffering
this is VERY well done mate
This is actually slightly low! In the early stages of the game, we don't need the "just in time 4" since the board isn't filled up yet, so we can afford to have all 2s spawn. I'm not gonna do the math, but I'm guessing the answer you gave is low by around a hundred or two.
I thought you had at least a million subs bloody hell you deserve more attention
easy to digest math and cool animations, darn doink it you just sniped yourself a subscriber
Holy shit. Well done buddy!
Doge: Dog + e as in best, not e as in equal. 😂👍
You seem so much like my brother. Sees random thing, instantly starts math.
You have a cool brother!
Right now I am at a 65k i think I have been playing this on and off for about a year or two 😅
Steven Nikolov I’ve been playing for about 2 months and I’ve got 60k 2wice
Subscribed. I wish you a lot of luck, your videos are very well done and interesting.
I am from Greece and yes Σ = S THX FOR DA HEART
Fk if i knew this before the surprise test on math (this was not taught because the test was designed for people 3 years older than us) I would’ve got even more points.
You're so close the the camera. AHHH! Nice vid though.
Yeah, my wide angle lens earns its keep in my studio. :)
Woah. Great job! A lot of math explanations assume prior knowledge or just give facts instead of working through them. This video (and your general style) require very little math background, but they still encourage math reasoning-which is exactly the thing that makes math more interesting and less scary. I hope this channel continues to grow-I’ll
keep watching!
Very well made video
What an amazing video! Thank you very much for this.
Who is playing 2048 in 2048?
I've already planned my tribute video, and it will be released on the 2048 SpaceTH-cam platform. Because we'll be in SPACE.
I had a version of the game that had an undo button. I used that to reach this score. You could only ever undo just the previous step, but the next tile would appear randomly every time.
Ooooh, that's useful. You could actually get this score with that game.
6:15
thank me later
I used to play this game in my way to school, and sometimes reached some incredible scores.
This video made me go back to those days, it was joyful and interesting! keep the good work
Why am I watching this at 3 in the morning
Me: How old are you?
Taylor: Somewhere between the age of 13 and 45.
That beeping in the music killed me
I personally didn't learn to much form this Video, but i really think this is a great video to get younger viewers tricked in to liking math
There was a version I used to play where you could undo your last move and redo it and repeat. Some of us actually reached that score (It only took weeks of playing and not messing up too bad)
I have just found this channel and after reading the comments I have figured that the channel just bloomed coz most of the comments are just a few days old. Keep doing the good job buddy hoping for some great videos from u in the future
I'm happy that I found your channel. Good production value, great and thorough explanations, awesome voice. Turns out that TH-cam recommendations aren't complete rubbish once in a blue moon :)
BTW, it may be a good example to show some series sums can be computed, first with the geometric series and then using a dummy variable and the derivative (though I don't think you've dealt with derivatives yet). The shorthand answer to this sum comes out as rather compact - > 15*(2^18 - 4)
True! I just kinda wanted the introduction to the sigma notation to be a gentle one in this video, but you are quite right.
Calculus is too advanced for most audience... also, you don’t need calculus to reduce it... you only need to times each term by 2 and cross subtract to reduce it into a geometric series...
@@TheTaylorSeries Totally understandable, I meant this as a possible suggestion in case you ever wanted to make videos about the subject of summation of series.
Other questions:
*A)* What's the _lowest_ possible winning score? For that you want a cascade of tiles from 1024 to 4. All made from 4s. Drop another 4, then drop 2s and 4s so they don't combine while the cascade collapses.
(My best score is 20032; just can't break 20k.)
*B)* What's the maximum possible _non_ -winning score? The highest possible set of tiles would be eight 1024s and eight 512s, arranged checkerboard-style. But you can't build up to that, so....
(My best score is 37784.)
Oooh, those are both very good questions. I shall have to think about them. Thanks! :)
Tumbnail says everything
I hope you get a lot of subs really quick you deserve it your work is fantastic keep it up! Btw you were correct the Σ (sigma) it's just a capital letter for the Greek letter s
There was a version that allowed for infinite undos. After solid 2 weeks of playing I finally managed to get the biggest combination on screen. I would have probably played twice as long if I was aiming for the maximum score as well.
@TheTaylorSeries
6:48 - You're correct!
Found this video, never before seen you, and I love it! You took something that would have taken me a few months to solve, and gotten it simplified where it would take me a few minutes to solve. You are better than most other math TH-camrs, because you make it something that only a Harvard student would understand, turned into something that a grade-school student would understand. Others would just give how they solved it, and give the solution, and that would be it. Not you, though. Thank you for that.
Excel is not required. The sum of powers of 2 (a geometric progression) is just 2^(n+1) - 1. Geometric progression formula is (1 - a^n)/(1 - a). Taking the derivative w.r.t. 'a' can yield a formula for the sum of n*(a^n). Anyhow answer can be arrived from (17*2^19 - 18*2^18) - (2*2^4 - 3*2^3) - 2^18 + 2^3 - (18 - 3)*4 = (17*2 - 19)*(2^18) - (2*2 - 4)*(2^3) - 60 = 15*(2^18) - 60 = 3932100.
You made maths interesting for me with this... But I have finished my school, college, now will get a job in 6 months. But I will study maths for sure.
There are several interesting questions.
What is the optimum strategy? ie. what strategy has the highest average score?
What is the miminum score? ie. is there a sequence of appearing 2s/4s on specific spots, that no matter how you play, you will loose after at most N steps?
What is the longest possible game? ie. assuming you don't want to combine tiles, but also not loose, how long can you play (in terms game steps).
What strategy has minimum average score? ie. the most efficient way to loose.
This video confirms my long held belief that I'm shit at math.
next video: calculating the probability
Man, I wish; that is a monster of a question. :)
I didn't expect to see a measly ~4.6k subs given how clean and well-done your videos are. You could give folks like Mathologer a run for their money. Good stuff, man! Subbed, and can't wait to see what you do next!
