Minesweeper in Minecraft: A 50x50 square of grass blocks, a player digs down to find either: a sign with a number 1-8 showing how many TNT blocks (mines) are ajdacent to that block or a TNT block/mine, causing an explosion and game over. Each 50x50 square would be generated with 15 randomly placed mines. If a player knows where a mine is, they can put a red banner on that block.
Rather interesting suggestion, inspired me to create a proof of concept... Before I show it off, it took about 5-6 days to complete. It could have been done quicker, but I needed a few breaks in between. Also I used minecraft functions instead of Java as I have not learned the language just yet. Now before you ask, yea I could have used command blocks, but I think they would be less efficient in this case. With that said, the proof of concept is in the spoiler below... Prerequisites...

I simply made it the way I did because I actually started this project long ago but gave up on it, then I came back and reused what I had already done 5-6 days ago and upgraded it. #2 You can change the number of mines that spawn in with the minefield by changing #mines score inside of "main.mcfunction". I know this isn't the most convenient way to do it, but like I said, it's a proof of concept... #3 You can also change #btp which stands for "blocks per tick". If you change it to a higher number, more blocks will be placed in the same tick whereas a lower number means less blocks in the same tick. I added in this functionality so that you can control how many blocks per tick are placed, however I wouldn't set it too high or you will lag the game. This also only affects the "Detector" item and not the other three which spawn the field in. #4 If you want to organize the files into a nicer file structure, feel free to do so. Just don't forget to change the function commands accordingly. The reason I didn't do this myself was to make it easier to fit everything into this post. #5 The main file that makes this function work is "game.mcfunction". Everything else is either there to help it work correctly, or spawn something like a minefield to play on. #6 This proof of concept was tested in 1.12.1, it won't work in 1.13. #7 If there are any other notes I forgot to add, I'll edit them in later. Whew, that was long. My apologies if I was confusing, or even went a little overboard, just trying to help... Oh yea, before I forget, +1. Thanks for reading!!! ~SUPERI0N
This would be really cool. Minesweeper was one of my first favorite computer games (along with the likes of pinball and solitaire). I'd love to see it implemented on the games server! It might be a lot harder to extract me from said server, but shhh. The one downside I can see is that minesweeper tends to be a SP game (and it's not even all that entertaining for spectators), and the /games server seems to be focused much more on MP stuff. Not sure if it's just due to the trouble of implementing a little 'side-dimension' for just one player, or if the focus is intended to be only on MP activities. Something to keep in mind.
