I Made Minesweeper with just Redstone!

[@mattbatwings]

Hi guys, thanks for watching! A couple FAQs: “50/50s were allowed in the original game. Doesn’t that mean 8s are necessary?” Yes, if you’re talking about the classic version of minesweeper. At the time, I genuinely didn’t know the original game allowed 50/50s. My entire career of playing minesweeper consisted of playing the google version a few times, of which I never ran into a 50/50, so I wrongly assumed the random generation will just avoid it. This is also why I gave up on random generation. Probably should've played a few more games / done more research lol “Can’t you cheese the win detection logic by flagging every cell?” Nope! The logic is based on the open signal and the mine signal, not the flag signal. The “Face” column is a bit misleading, whoops!

I used to be so confused about how the first computers were made because don't you need a computer to code a computer but your videos really helped me understand how that was possible. Your videos are so interesting and entertaining, thanks for making them.

[@1mariomaniac]

The first computers were actually incredibly big! Usually taking up most of a room in fact! They'd compute complex mathematical operations, and even basic simulations. They were programmed and given inputs via punch cards, which would then be processed, and depending on the operation, would either install whatever simple program you punched out, or would display an output via lamps, printer, or electric typewriter. The IBM 350 RAMAC is a great example of such a system. Capable of storing 62,500 punched cards worth of data (roughly 3.75Mb) which was incredibly impressive in 1956!

[@vampire_catgirl]

^ So big that literal bugs could easily make their way inside and then mess up the system, which is where the programming term "bugs" comes from in the first place

[@nicolasbilal8769]

Amazing. Saw your post on Reddit and thought, “this looks like something Matt would do” then I checked the user and sure enough! I was kinda hoping hitting the mine would blow the whole game up in the showcase, we gotta raise the stakes 😂. It would also be nice to see a mine counter, as well as a question mark marker for the cells you’re not too sure about, but that last one isn’t too important. Additionally I would be very interested in a series that serves as an in depth guide to each of these machines starting from more basic games and gradually becoming more difficult. I think I’d learn a lot more that way! Love the content! You never let me down. Can’t wait to see what you come up with next!

[@bw1llis]

second the explosion! put some tnt under each of the mines!

[@jamiebell2777]

I was expecting the board to blow up when you found a mine in the showcase hahaha. Awesome stuff! This was a really fun video to follow along, and some super neat tricks I wouldn't have thought of :)

[@TheGunMasterDigital]

Nice video! This is such a fun project too, I remember building my own in the past. It's perfect for not being too difficult, yet still being fun and satisfying to play, even if it's quite slow due to redstone's speed limitations.

[@SlymrMC]

I know I'm a bit late, but now 1.21 has released, you could use the crafter to store 'mines' (TNT maybe) and generate mines like that (have the 'mine' reps flow in through hoppers)

[@XAORESS]

It's always a pleasure every time you explain how the game works and the components associated with it.

[@SprinchelArt]

You forgot the most crucial part!!! You should've made a map where the lose condition activates tnt that's spread all over the circuit That's like... The most fun thing to watch in minesweeper

[@benjaminphipps8325]

You’re the most impressive redstoner by far. Both because of the absurdity of your builds and the simplicity you explain things with

[@vistaman1]

you should have kept 8, its a really small chance but sometimes you could get an 8 on the first cell you click

[@zutaca2825]

but if you do that, you have to guess what cell outside of the 3x3 surrounding it doesn't have a mine, and he wanted to avoid boards where you need to make a 50/50 guess

[@Waluigiredstone]

also he should make a flag counter or some from of flag spam detector. you can just win by flag all the blocks

[@Lcfp]

@@Waluigiredstone you're absolutely right. Furthermore you don't have to flag all the mines in order to win, they just need to remain closed, so the correct win condition is not "all the cells are either open and not mines, or flagged", but "all non-mine cells are open"

[@mattbatwings]

@@Waluigiredstone check the pinned FAQ!

[@rahevar3626]

No you can't get an 8 on the first click. Infact you can't get any number on first click. In the game first click always results in a zero. Otherwise you would need to guess for the next cell

[@floschy_1]

[@Kallyn]

I had to code Minesweeper as a final project in my programming class. Detecting adjacent mines really was as simple as a for loop. As I was watching I was thinking about how it would be possible to do each step in redstone, and each time you revealed a step my mind was blown and I audibly said "that's so cool" or "that's so smart." I kinda wanna try it out myself now even if I know I won't be able to do it

[@BleachWizz]

12:50 - IKR! In the end it's like you do your stuff and tell others if you've done it so they can see if they have to do as well. it's the event pattern, very efficient and one thing to use a lot in game dev.

[@TheGamingTurret]

You should share this video with Xumavoid on Hermitcraft, he's been cracking away at trying to build a more elaborate version of minesweeper (The mine sweeper game despenses TNT when you click a mine).

[@Huntracony]

You went a lot further than I would've thought already, but my favorite convenience feature is missing: in most versions, clicking an unlocked tile will unlock all the neighbors that aren't flagged. I bring it up because I actually think it's pretty easy to implement, at least logic wise: send the same signal that zero-spreading does to its neighbors, block that signal when it's flagged. The hardest part would probably be finding space for that wiring.

[@anthonycannet1305]

[@element1192]

Why not add a random mine generator? Normal minesweeper has 50/50 guesses all the time, you don't have to account for that

[@TheGooodGMD]

I tried adding it once to a minesweeper game I made and it was a hassle to say the least

[@johnschaefer4905]

This is really cool. Theoretically, you could add a difficulty level where you just multiple the size of the table, and use the old cells as new individual redstone lamps.

[@danielrhouck]

A couple comments: 1. Most minesweeper implementations don’t go out of their way to avoid making you guess, which would make game generation easier but means an 8 is necessary. Similarly even if you do avoid that, you usually know the mine count even if there isn’t an up-to-date counter of that minus the number of flags, so again, 8 is useful. 2. If you’re willing to make the game one-time only, or you’re willing to use command blocks for reset, you could make the lose state much more thematic in a way most minesweeper implementations cannot.

[@Santra007]

bro you are so good hats off

[@kyleclarke4845]

This is incredible. I made minesweeper in Javascript afew years ago and it took me like 2 months... no way I would have the dedication to make it in redstone

[@tminusboom2140]

If you use a hopper based T-Flip flop, you can guarentee a full reset by disabling the universal block and briefly inputting a specific side block. This forces the item to always be in a given position.

[@flameofthephoenix8395]

8:57 Aha! I was spot on, I figured you were just subtracting one for each of the nearby mines then subtracting that result from eight to get the number of mines! Of course, if I continue watching only to find out that that's not actually what you did...

[@sootish]

woah i was just thinking of trying to make something like this! this is insane, holy shit. kudos to you!

[@LyricNear]

it's insane to me how people are able to adapt to a new universe with new laws of physics (ie redstone wires having a strength meter built-in to them vs real life wiring would take such complicated systems to implement the same thing that it wouldn't be worth it) and come up with such creative solutions to take advantage of them! This is on the same level as early pinball machines to me... just an amazing feat of electromechanic engineering and code done within a different universe.

[@manojkathiriya8763]

One time I was playing Minesweeper in normal difficulty. When I just clicked a random cell all the safe cells opened due to zero spreading and I instantly won!!!

[@SWRDMaster]

50/50's occur in most minesweeper games; unless you look for a version to filter those out. With vanilla the statistical best you can do is win around 30% of games; I'm steady at just above 21% with a min time of 120s for expert (over 10,700 games). I'd want to use a counter to set the number of mines, an x & a y randomizer to select the positions, and a return signal to try again if the attempted mine placement already had a mine. Remaining unflagged mines count is also a critical number to determine if certain areas are safe, especially on larger boards. A timer wouldn't be too hard to add either. Glad to see the vid but also having a strong dejavu moment; almost like this was a re-upload but I know it's not.

[@bork6996]

Fun fact, wich goes hand in hand with board generation. In the official game the board actually isn't generated until the first click. This is because your first click will ALWAYS be a 0/empty space.

For randomising the mines if you were building a 9x9 you can just use 2 droppers and an item sorter and get a signal strength from there and set them to the mine selection area and each item in the droppers will say like “6,3” to map along 6 and up 3 like cords in math

[@simonwillover4175]

Idea for how to increase the chance of a random minesweeper board being winnable: Make a noise map using a maze generator, and then have the maze walls be weights for a higher chance of a mine. This is increases the chance that zeroes will be adjacent to eachother and decreases the chance of dense rectangles of mines. Use multiple layers of noise to give the field a larger (general) structure.

[@danielisenberg2360]

Honestly I would have just left the zero spreading up the the player lol. However, your implementation of it is beautiful. Also, I once made a very different kind of redstone minesweeper that was much simpler but unfortunately a one time use device if you lost. Each cell was just one block and had some generic block like stone on top. You could "click" a cell by breaking the block or "flag" it by placing a carpet over it. Under the top layer would either be an iron block for a 0, blue concrete for a one, green concrete for a 2, etc, etc, so it was all color coded. If you clicked/broke a block with a mine under it, there would instead be an observer with a tnt block underneath which would then detonate. Each game had to be manually constructed and it generally killed you and also destroyed the whole board if you lost.

[@STIMULAT10N]

The fact that you didn't blow it up with TNTs in the end was highly unsatisfying (/j, this is impressive!)
