If you owned a PC before the internet became a thing, chances are you spent a fair amount of time playing Minesweeper. But it turns out that some people never stopped playing Minesweeper and these people take it very, very seriously indeed.
This fascinating mini-documentary explains some of the finer facets of Minesweeper, including its history, where the game is headed, and the numerous different ways people play it. As always, when human beings decide to dedicate themselves to one single endeavour, tremendous things tend to happen.
Just for the record, I've posted a Minesweeper 'speedrun' just so you can get an idea of how insane people can get at this game.
This one is also incredible. Minesweeper is serious business.
