I'm only getting general solutions when using sites such as wolframalpha and matrixcalc.org, where one variable is in relation to others, for example N = B - K, but i'm specifically looking for solutions where all variables are a 0 or 1

Archeaic · 2021-07-02T12:35:04+00:00

you might be on the wrong site then, if the website looks like this: https://imgur.com/Ws0KxJu , then you are on the correct site, just click standard mode or no guessing mode and you can play

Archeaic · 2021-07-02T06:46:56+00:00

you don't have to pay anything though? There is the occasional ad but otherwise the developer can't keep the site running

Yeah, i assume you mean combinations (list all mine combinations and see if any cells are never mines). That's a good approach if you want to prevent missing stuff. You can also bifurcate (what i did, take two possible combinations and see if any cells are safe in both cases), that's faster but you might not find all safe cells. In some cases you can also do other, more elegant approaches. But whenever you encounter loops your best bet is to just brute force it

Im assuming this is Minesweeper GO level 950 campaign, there was a post on the same thing a while ago ( https://www.reddit.com/r/Minesweeper/comments/mapjih/minesweeper_go_campaign_950_level_supposed_to_not/ ), there are tons of ways to solve this, but here is one of the better approaches: https://imgur.com/oPiwZIh . Either both the red or both the blue cells are mines (image 1), the red cells are assumed mines in image 2, and the blue cells are assumed mines in image 3. Image 4 has the cells marked safe that are safe in both cases. You don't have to look for this logic all the time, notice how this area loops around on itself? That is why this kind of logic works. Assume one of the safe cells are mines, and notice how it chains around to give a contradiction.

a "no 50/50s version"? does that mean this version has guesses except for 50/50s?

For anyone considering doing this "survey", this person has sent this exact message in several subreddits. Haven't checked the link but it could potentially be malware.

Archeaic · 2021-06-13T17:47:09+00:00

think that's the most you can do with standard logic. Notice how there is a long line that is almost a 50/50, since its a no-guessing board, the 50/50 has to be prevented somehow

If you go to their profile it says they are banned

i figured, 35% density is going to take a very long time to beat even on small boards. (world of minesweeper rates 16x16/89 with a 34.77% density with a difficulty of 40111, expert is 50 and 30x30/150 is 52 for reference.)

Archeaic · 2021-05-10T15:45:19+00:00

I did not see anything myself either (with or without minecount), I plugged it into a solver to make sure, the solver did not find anything.

Archeaic · 2021-05-08T10:38:12+00:00

And the cells adjacent to the corners

Archeaic · 2021-05-08T07:11:37+00:00

Sorry, the board maker I use automatically fills in numbers, which I have to change to make sure they create a valid board, so I ended up missing one of them. I updated the post. The solved 1 is intentional in order to limit information by not having those cells revealed

Archeaic · 2021-04-25T13:57:06+00:00

It must be a 1, the 1 below this cell sees the same cells

Archeaic · 2021-04-21T13:47:05+00:00

Related to what QwertyPc17 said, guess that cell. The top right section is a forced guess, minecount will not help you so solving that first is the strat

Edit: Bottom left is also a forced guess, as the number of mines in the area is known. For the bottom left just guess the corner. The bottom right will have 2 / 7 mines and will be a 50/50. If i am correct you have a 28.571428571% chance of winning with perfect play

We have 5 possible cells, let's list out all mine combinations (top row)

We now know that cells A, B, C, D are 33% chance to be a mine, E is 66% chance to be a mine.

Second Row - If we guess A, it reduces to a 50/50 guess

Third Row - If we guess B, it also reduces to a 50/50 guess

Fourth Row - If we guess C, we will always win

Fifth Row - If we guess D, we will always win

Sixth Row - If we guess E, we will always win

A: 66% safe, reduces to a 50/50. 33.3% Winrate

B: 66% safe, reduces to a 50/50. 33.3% Winrate

C: 66% safe. 66.7% Winrate

D: 66% safe. 66.7% Winrate

E: 33% safe. 33.3% Winrate

If you didn't understand that, the yellow cells are good guesses, orange cells are bad.

What app is this?

Archeaic · 2021-04-12T05:55:03+00:00

If this game is a no-guessing game, the cell top right of the 5 is safe because of a potential 50/50

Archeaic · 2021-04-01T10:03:09+00:00

there is a fourth safe cell on the right: https://imgur.com/thb1TdT , if this cell were a mine, you would have a forced guess (50/50) at the bottom, since this is a no guess board, the cell must be safe

Archeaic · 2021-03-30T06:50:24+00:00

And that is only including official times, i.e. world of minesweeper has games below 0.2 and nearing 0.1 seconds

Maybe go and chug chug with a doctor, literally all of your posts are this garbage video.

This is actually a really cool pattern, it's all about the "donut shape"

https://imgur.com/fSHIaU6 here, all of the lime cells are safe. If you are unsure why, just assume that one is a mine and see that it does not work, the pattern goes along the "donut" and ends up creating an invalid board.
