"Yes, but what about 27" - Oh, hello. Glad you asked. Don't stand up now. Under your chair there is a bomb. It will blow up if you stand up, or if the square you uncover in the next game you play is a bomb. The bomb under your chair will self-disarm if you successfully mark all the bombs on the board. Welcome to 4D minesweeper, where the highest number you can uncover is 80. Oh, also, if you ask about 81, the bomb under your chair will blow up.

In Minesweeper, a "9" is a 3x3 array of mines. It's not a real number you can get. However, it is exceptionally rare.

[@pokepress]

I assume the part where it gets really bad is where you have two 3*3 groups that have a ring of mines on the outside, but you know based on the number of remaining mines that one has a mine in the middle, and the other doesn’t, basically making you make a blind 50/50 guess.

[@valseedian]

@@pokepress expert games are highly likely to end in a true 50:50 guess. more than 50% but probably not much more. I think the linear algebra solving technique can reach 45% solve success but I'm not sure if that includes successful 50:50 guesses. my own solver will halt and start a new game if it detects any 50:50 guess, but it only looks for those if there are no detectable safe squares. but my solver doesn't detect 7s exactly (because 7s are the same color as bombs if i only detect 3 bombs or less on a board I treat them all as 7s) and won't detect 8s at all because they aren't solve probative.

[@OrangeC7]

My first thought was that you actually could have numbers greater than 9 in a minesweeper board with hyperbolic geometry

[@EvilParagon4]

Back in highschool I used to always play a 83x38 custom board with 750 mines to pass the day instead of doing classwork. This was basically fullscreen minesweeper for my laptop and had a density of 23.78%, so just a little bit harder than expert. It took me a whole year to finally win a game lol. It took about 4 hours to get to the end game, but with a board and density of that size, the probability of getting way 4-6 pure 50/50 choices was basically guaranteed. It was a coinflip until you win at that point. Keep in mind you need to first get to that stage, which could have misclicks or even just a small but quick lapse in thinking could end your entire game.

[@mallomon]

For the 8 in the shape of an 8, it made some sense to me. If you have one 8 already, you're using 8 of your mines in that 8, and these 8 mines are arranged in four edges of three consecutive mines. If you are to have another 8 on the board, starting with one of those edges gets you 3/8 of the way there, and requires you to use up three fewer of the total mine allotment. So it should be much more likely than random chance that, knowing you have an 8 on the board already, and knowing you have a second 8 somewhere, the second 8 would share an edge with the first

[@radeklew1]

Yes, two 8s involve the positions of 16 mines, while a figure 8 only involves 13 mines, but with additional constraints on position, so it mrke sense that those two effects roughly cancel each other out

[@GamesComputersPlay]

You (and other people saying they were not surprised) seem to have a well tuned probability intuition. Now, when I know the answer - yeah, I guess it makes sense. Bit when I saw the results for the first time, I was really suspicious there was a bug somewhere. Was totally in disagreement with my intuition, and even nwo it still rubs against it a little. For me it stands right next to the birthday paradox and Monty Hall paradox. (which fooled my intuition too the first time)

[@platinummyrr]

yup. The fact that 8s can re-use the same mines is why its much more likely!

[@jonathanblake831]

[@zuthalsoraniz6764]

Yep. Despite the fact that there are a lot more ways to arrange two 8s on an intermediate board than one double 8, the 24 free mines on 238 cells of the two individual 8s gives ~5.3*10^32 remaining mine patterns per two 8s pattern, while the 27 free mines on 241 cells of the double 8 gives ~ 4.2*10^35 random mine patterns per double 8 pattern.

[@Kpsla]

The 8-8 thing makes sense to me. To get two full 8's, you need 16 mines to be placed exactly right, but for one single 8-8, you only need 13 mines to be placed in the right pattern. Or, thinking about it more abstractly, once an 8 has already been placed, there are only 5 mines that need to be placed after that to make that 8 an 8-8.

It’s more than that. Reducing 8 to 5 definitely improves its chance, but it’s really down to the limited number of available mines that makes it so likely to occur. The fewer mines available, the more likely the two 8s will have to share them. If you have few enough mines (e.g. 14) regardless of the board size, the chance becomes 100% because there’s simply no other way that two 8s can physically form on the board.

[@webrunner42]

In Super Mario 64 speedruns whenever something occurs that would make two sets of records (such as 120 vs 70 star, then 16 star, then 1 star, then 0 star) they just split the leaderboards. Super Mario World also has two common Any%s: regular gameplay vs using the Arbitrary Code Execution glitch to jump to the credits from level 1. I think minesweeper could do the same.. have a 8x8 leaderboard and a 9x9 leaderboard.

[@EebstertheGreat]

Speedrunning beginner is sort of pointless imo. As the creator pointed out, you can beat beginner in a single click with 0 on the clock. These zeroes are simply not counted on the leaderboard, because otherwise the top of the leaderboard would just be full of them. So instead, you have to click at least twice. That means people who want to grind a good beginner time just keep refreshing the board and randomly clicking twice. Each time randomly clicking twice doesn't win, they refresh. They try to click as fast as possible, maybe using a mouse that double clicks if you push the button right (usually an undesirable behavior). For instance, the minesweeper online #1 time is 0.02 seconds, apparently accomplished by dragging the mouse along the top of the board. Splitting the 8x8 and 9x9 times wouldn't change that. Beginner is just silly.

[@GamesComputersPlay]

Interesting point. I actually agree about 2-click being mostly luck. What they did about it is they introduced Beginner 3BV category that limit minimal 3BV at 10. It helps somewhat, still they have a few disqualified attempts because "there was one lucky click". Which is now a bit weird. So what, lucky click? If at the shooting competition I shoot without looking and hit bull's eye, I still get the prize, right?

[@EebstertheGreat]

@@GamesComputersPlay Yeah, it also must be incredibly frustrating to try to grind. Every top time must be "lucky" to some extent, so it feels like if you get _too_ lucky, then it just doesn't count anymore. Imagine if whenever a golfer got two holes in one in a single round, that round got disqualified.

[@andy02q]

@@GamesComputersPlay What is the chance to beat a beginner board with a 3BV of at least 10 with only random clicks? If it's less than a million, then there's a real chance to piss off some pros. :D

I got really good at this at one point, and I used to play a larger board. I think 24x30 with ~165 mines. I remember the cutoff was pretty sharp, where most games under that number of mines were easily solvable with good initial guesses. More than that and I had to start making too many good guesses to win. I never ran probabilities though.

[@nicholasiverson9784]

The two 8s in an 8 configuration odds are actually fairly intuitive. Given an 8 on the board, there are two places (as long as it's not too close to an edge - and assuming you want them vertically orthogonally connected) where there are already 3 mines in a row. Requiring only 5 mines to be in specific places, to accomplish the goal of two 8s. Where a disconnected 8 on the same board as your 8 requires 8 specific mine placements. The reason it's only 1/3 as likely as finding a 2nd 8 floating in some unknown far off location is because there are significantly more than 2 places those 8 specific mines could be arranged than 2. But that only just over compensates for the 8th power vs. 5th power comparison.

[@superdupergrover9857]

Hmm. I always assumed that Minesweeper solved the "first click problem" by choosing an appropriate board after the first click. It would keep randomly producing boards until a compatible one revealed itself.

[@GamesComputersPlay]

To be honest, I couldn't find any reliable info about latest minesweeper clones and how they handle it. But for old version - yes, they just move a mine. Also, I think they do create new board in "no guessing" mode in some implementations. (As just moving mine can create a guessing situation).

[@atlekristiansen4975]

I have wondered about this "What if the first click is a mine"-issue and how they solve it, when you're suppose to be safe that one time. There 's actually a Game Boy versjon of "Minecraft", which «solves» the whole problem by letting you actually get a bomb on your first click... kzbin.info/www/bejne/fl7Ufqyvjqdooa8

[@wormalism]

The best way would be to shift the whole board down and to the right to the first safe spot, wrapping the bottom rows to the top and the rightmost columns to the left.

[@valseedian]

@@GamesComputersPlay almost every "no guess mode" version tells you which first click to make. they generate these boards by actually solving them and when a situation is reached that would be unsolvable it moves mines then to currently uncleared spaces that aren't associated with a cascade and continues solving. if it can't find a place in uncleared blocks, it puts it in any space that doesn't boarder any other mine. if a move was moved in this way it begins solving again from the beginning. seeds for these states with the starting square are pre generated and stored, often by brute force. my approach is slightly different. I run a solver that doesn't guess on my home computer and note seeds and starting clicks for any win. those are innately solvable too.

[@Slush_]

In University I worked on a machine learning algorithm to play Minesweeper (with... mixed results, I was a rookie), and 1-click games became a serious problem. Turns out my board wasn't dense enough and they were more common than they should have been, it fed the algorithm a ton of bad habits because that click ended up with a massive reward score. That one eluded me for a while...

[@guyinacage]

I think the reason the 8 of 8s is so likely is because it shares 3 mines between the two 8s. The configuration requires only 13 mines and the remaining mines can be anywhere else, while having two separate 8s would require a whole 16 mines split into two groups. I think it is misleading to compare the chance of getting an 8 of 8s to the chance of getting two separate 8s. Instead, the 8 of 8s should be viewed as its own kind of shape, and the chance of it appearing can be compared to the chance of two regular 8s that are not joined. It would be interesting to calculate what the chance of finding two 8s that share any number of bomb tiles is compared to finding two disconnected 8s. I would bet that it'd be more likely than not that if there are two 8-tiles on the grid, that they share at least one bomb.

[@GamesComputersPlay]

hey, let me run that. I'll report back.

[@GamesComputersPlay]

ok, I ran a bigger simulations (220M), here's what I have: - just 2 eights: 122, 1/1.8M - 8s that touch each other at least in one spot: 88, 1/2.5M - 8 in a shape of 8: 71, 1/3.1M So: - Looks like my estimation of just having 2 eight maybe was a bit off in the video, it's looks to be more rare. However, it makes the "8 in the shape of 8" paradox even more prominent: difference between those are even smaller than 2 - You prediction that touching 8s are more common than non-touchin is quite true: almost 3/4 are touching each other. - estimation of 8 in the shape of eight still stands 3.1M and 3.2M - close enough.

It breaks for bigger numbers, but should work for everything in the video: 8, 9, 77, 8in8.

[@andrewsauer9669]

The reason double 8 is not that much more unlikely is because it requires less mines in the formation than two 8s by themselves, allowing more leeway for the rest of the mines.

[@WolfieNamira]

These probabilities make me want to have all ~7 billion people on earth to play minesweeper once just to see what boards have these rare things lol

The double 8 thing makes sense, because it only has to have 13 mines in a set position, rather than 2 sets of 8 in set positions.

[@JayTrip05]

Lol, everyone is posting on this

[@JayTrip05]

The reason the probability of the two eights being close to each other is so high is because it's easier for 5 mines with one space in the middle to spawn close to the 8 than it is for an entirely different ring of 8s to spawn. In essence, they are simply both 5s sharing 3 mines, not two completely separate 8s. As to them being on top of each other, not necessarily. The same logic applies sideways, where they could form the shape of an infinity symbol. I hope this explanation makes sense.

[@JayTrip05]

I will admit, Mallomon posted on this first, so credit where credit is due, however, I had no idea they had posted until just now.

that 3d minesweeper is a real thing it is especially amazing if you can play it in vr and i personally find it very fun

[@zuthalsoraniz6764]

The correct way to calculate it would be a multi-step process. First step: Calculate the total number of different mine patterns, this is [number of squares] choose [number of mines], so 64 choose 10 or 151473214816 for the old beginner board. Next, calculate how many different ways your chosen pattern fits on the board. For the 8, that is 36 different ways - the 8's center square can lie on any of the 36 non-edge squares of the 8x8 board. Then, calculate how many different ways the non-pattern mines can be arranged for each of those ways - in the case of the 8, that is 55 choose 2 - two mines remaining, and we have used up 9 of the board squares for the 8, giving a result of 1485. Multiply the latter two numbers together, and divide by the first, to get in this case 36*1485/151473214816=3.53e-7 or about 1 in 2.83 million odds. This also shows why the 9/filled 8 is so much less likely in the beginner board: It only has one additional mine left, so there are in total only 1980 patterns that give you it, vs 53460 patterns that yield the normal 8. This also means that on the new 9x9 beginner board, the chance for an 8 is 49*2556/1878392407320=1 in ~15 million - yes, there are more than ten times as many total different mine patterns on the 9x9 board as there are on the 8x8 board!

It's funny when thinking about 4D minesweeper, it occurred to me that if you play two 3D games at the same time, alternating turns on each board, you can conceptualize that they're the same board taken at different times where the mines have moved.

The eights paradox completely makes sense to me. If you have two eights on your board it can involve up to 16 mines. However, having two eights next to each other only depends on 13 mines since some are shared between the two eights. So it should actually be more likely to get the two eights next to each other than not sharing any mines between them, purely because having to independently and randomly placing more mines in specific spots exponentially reduces the odds with every added mine. It also makes perfect sense that out of all possible arrangements of two eights the most likely one is them being adjacent, for exactly the same reasons

[@3141minecraft]

[@theunknown4834]

This minesweeper is different from the original one. 0/10 lies were spouted out all jokes aside, wow, this is the sequel I needed

[@hoppygrob3590]

There is no 9 because seven ate nine

[@GamesComputersPlay]

That's the kind of joke I should have thought of. Alright, here I go: But why did it ate nine? Because it needed three square meals a day!

[@bkCheezburgor]

Bro i Had to delete this joke

[@egwenealvereiscool7726]

12:45 Its because getting 2 8s next to each other uses less than 2x the number of mines; The total number of mines is not sixteen, but eight (from the first) plus five (eight from the second minus the overpap), so thirteen. This increases the probability a lot. This approximately cancels out with the chance that the two formations (one with eight and one with five mines, and each having one blank) appear right next to each other.

[@doodeedah6409]

I think it makes sense that the chance of getting two 8s next to each other is relatively likely compared to getting two 8s anywhere. It’s because there are only a limited number of mines on the board - the fewer there are the more likely the two 8s will have to share mines. In fact, if you have few enough mines (e.g. 14) on any board size, the chance of the two 8s to be next to each other is 100%, i.e. they can’t physically form anywhere else.

[@blazingkite8983]

"first click is always safe" Well given that windows seems to have different versions for minesweeper throughout the years I dont know if this is also a version case but I do have actually hit mines first click essentially found cuz I was bored and just click once and start new board just for the hell of it.

[@rishitpant]

3D one it so cool! Gotta try my hands on it.

[@dancoroian1]

It's because the 2 8s together only require 13 mines (in a certain arrangement) to create, whereas 2 separate 8s need 16 mines in a certain configuration. Basically when you already have one 8, you just need to get lucky with the placement of a "5" to get the figure-8/infinity shape, rather than having 2 incredibly unlikely 8s occur independent of each other

[@jasontermini8487]

so i just have to play 108 million beginner boards to see an 8? welp off i go

[@sarojandongol1482]

I'm glad I get to be in the 1 click gang.

[@Skylos]

I think what people meant with "What about 9?" is just a 3x3 area with all mines. No numbers, all mines. I THINK that is what people meant

[@GamesComputersPlay]

Yeah, I guess I figured it's not pure trolling at some point, but kept the game up, cause some of that I think was indeed a lighthearted troll-like fun.

[@HPD1171]

the two 8 being more likely then you thought makes sense given that the second 8 only needs 5 additional mines to be arranged exactly instead of an additional 8 if it were to exist somewhere else on the board

[@orang1921]

That 3d Minesweeper is crazy

Indeed, but if you think that was crazy, stay tuned for the upcoming video (maybe in couple of weeks), as I will be "adding the whole new dimension" to that.

The algorithm has decided his fate is playing minesweeper

[@gilliesiut2332]

If you make the density 99% you always get a one click win. Screwing around with this is how I learned the double 8 rule as a kid

[@GamesComputersPlay]

Sorry to get technical (channeling my inner Sheldon Cooper here), but 99% density will give you 5 non-mine cells on Expert and 3 non-mine cells on Intermediate - games, which are astronomically unwinnable. Making the number of mines X*Y-1 would, indeed, guarantee a 1-click win.

[@Vexy93]

I actually did lose a lot of minesweeper games at the first click when I was a child...

[@Mishigck]

Just got an 8 right before watching this video😂

[@silverheart302]

I would guess the 8s spawn in an 8 pattern because that setup utilizes less mines than having two separate mine circles, so it's more likely to occur with the amount of mines placed on an expert board

[@SigmaNeo426]

I remember playing minesweeper with my friend in 3rd grade. I press the middle, and win. i felt soo cool back then

[@RexVelde]

For the double 7, am I mistaken or is it pretty simple (without all this text) to solve with math on the begginer difficulty? In a 8×8 grid, there are obviously 64 cells. To get the desired formation of mines, there are exactly 10 mines used. By counting how many different positin the center can be in, it is 6 ways along the axis with the fewer mines and 5 ways with the more mines. Therefore there are (5×6)×2 positions for the formation to exist. Because there are exactly 10 cells we must fill, and each cell filled makes one less cell possible to fill, which gives: First mine: 10 availible cells in the grid (64 empty cells) Second mine given the first mine is correct: 9 availible cells int he grid which has now 63 empty cells Third 8 positions with 62 positions availible And so on. It may be written like 10!/(64!/(64-10)!) = 10!×54!/64! This gives the probability of the desired formation with a number between 0 and 1. To get it expressed by 1 in some number, simply inverse it. Because of the 60 positions the formation can take, multiply by 60. Final equation: 60 × 64!/(10!×54!) = 2.525 × 10^9 ≈ 2.5 × 10^9 Hope it was not too difficult, I recommend googling "nPr" and "nCr", which tells us about the number of combinations desired.

[@GamesComputersPlay]

That's exactly right.

[@monmagog]

Everyone’s gansta until the 9 pops up

[@B3Band]

When I think of "9" I think of a bomb surrounded completely by other bombs. So you would have no way of knowing what's in the middle until the very end of the game.

[@GamesComputersPlay]

Yeah, turns out it is a slang name for that.

[@ThymeLost]

I used to get a mine on the first click back when I played.

[@GamesComputersPlay]

I guess it wasn't Windows minesweeper?

[@ThymeLost]

@@GamesComputersPlay I was the windows that came with windows 98 I think. I didn't play none windows minesweeper. Sometimes I'd start in the corners and the first click would be a mine. Sometimes it would happen in the middle of the field. It might have been windows95.

Great stuff! Really enjoyed the video! The probability of two "8's" in the shape of an 8 did surprise me. Video format seems really close to @TwoMinutePapers

Fact check true: I do know what a gerund is - knew that for about 25 years by now. However knowing what gerind is, is one thing. Using it in your speaking, let alone youtubing - is just asking too much.

[@AranMiller]

16:05 EASILY one of the best endings of a KZbin video I have ever seen!

[@StefanVeenstra]

When you find 8 mines encircling one undiscovered square and you feel like a legend for it should be the rare, shiny 8, only for it to be the 9th mine.

[@siegeking9949]

In my years of playing minesweeper, every first click was a 0, not just not a mine.

[@GamesComputersPlay]

Yes, there are implementations that guarantees openings on first click. But the classic one is just "not mine"

[@ChallengeSpaceYard]

I believe the trend of opening with a 0 in Microsoft Minesweepers started with Vista. Some 3rd-party apps do this, too.

[@jamcdonald120]

12:55 it happens because to get 2 disjoint 8s you need 16 bombs, but for a double 8 in the shape of an 8, you only need 13 bombs

[@petersmythe6462]

Would be interesting to have a multiplayer minesweeper kinda like battleship. Each side places their mines and then takes turns clicking each other's board.

[@GamesComputersPlay]

The winning strategy would be to place as many 50/50 as possible. Unless it were against the rules and only "no guessing" mines were allowed.

[@bkCheezburgor]

Riririeiieieieiririririttoir

[@laurynastruskauskas6586]

Lol, i once got a circle of mines and i was so happy that i got an 8 which up to that point i thought was somehow prevented from happening. So i pressed it and there was a mine there, it really pissed me off, but now i know that it was even rarer and i got a screenshot of it so yayy i guess.

[@davidhopkins6946]

There have been 2 occasions where I got an 8 in expert mode. The first time, I unluckily hit a mine before I got to the part of the board with the 8. The second time, I solved the whole board, but the game unexpectedly quit a fraction of a second later. I also had one instance of 2 sevens with no shared mines in expert mode (i.e. a total of 14 mines around the sevens). They were by no means near each other on that board. I have never had an 8 in intermediate, but have had 7 in intermediate three times.

[@kuwejtyt1680]

suggestion: board without 4's, 5's, 6's etc.
