No guessing

[MrCavey]

Recently played a game on expert level with no guessing turned on and got to a 50/50 chancePhoto

Few more examples

Both from same game

Thanks for your feedback! :) Yes. Currently the No guessing algorithm may fail in some circumstances (or it fails to find a 100% solvable map in a short period). I'm currently thinking on a new version of it, so I will let your issue open until fix the algorithm.

I also found a scenario like this. The corner is not solvable without a 50% guess between the cornerpiece and the one below. Perhaps more examples help with figuring it out, so I thought I should share :)

and this: a 50% guess on 3 mines.

On the next update a warning will be shown when the level generator fail to create a guess-free minefield. I hope this helps.

https://github.com/chrisboyle/sgtpuzzles You can take a look at this puzzle compilation, it has minesweeper with a flawless no-guessing mode. I tried it with parameters that yours consistently fails with (standard mode with 40-50+ mines), and since it's open source, I thought you could take a peek at how they've done it.

@BloodRaven0 I will take a look.

@BloodRaven0 I was able to import the exact same algorithm from Simon Tatham's mines. It will be added with #321 on version 14.2.0.

An example of a minefield generated with this algorithm that wouldn't be generated by the old one:

Awesome, I'm so excited about this!
