It's like.. don't click randomly anywhere, right? If you are so unlucky to step on the mine with first click, just start new game.
Are we both talking about the first game click? It seems like you're talking about midgame situation, when you see no more mines, but you have found 8 of 20 yet. I believe you are supposed to place probes on the scanned area only. If you're thinking about the midgame, what you suggest is a huge gameplay change imo.
I do mean in the middle of the game, and all I'm suggesting is that if you click directly on a mine in the middle of nowhere that you haven't scanned, rather than unavoidably dying completely by chance which is frustrating and prematurely ends the game, the mine would be moved just slightly away from where the player clicked, completely without their knowledge of course, avoiding this frustration without the player even realizing that this is happening. This way losing feels less random. the strategy of only placing probes in scanned areas adresses the problem somewhat, but if you're trying to win with the fewest possible probes, the best strategy is to take your chances in the unscanned zones, which can be not very fun. From a game design point of view, we don't want to make the most effective strategy one that is tedious or frustrating, and I think this change would be beneficial to that end.
