I recently got a verified run (intermediate, no RNG manipulation) that was 1:38 but I was able to get an unrecorded 0:58 earlier today using a feature in the version of windows 10 minesweeper attached to this category. If you fail on a minesweeper board it lets you retry the same board so you start out knowing where some of the mines are placed. My verified run doesn't use this feature but I couldn't determine whether or not this was allowed because the rules about that are kinda vague. It might fall under the "no hints" category but I'm not sure.

You'd have to see what the mods say but I'd think it would be a new category or straight disallowed. If runs reused boards with the current leaderboards, it would an unfair disadvantage.

If you know where the mines are placed before you play, your run belongs to the RNG manip category. End of conversation.

Thank you for the clarification, I had not read the rules for that category before I posted on this forum.
