I learned it from other classmates in like my last year of high school. Then i mineswept a huge one with a high density of mines. What a waste of time. It was good for a younger kidnto make their mjnds sharper

No idea. But I had more fun _avoiding_ that yellow dot.

As someone old enough to experience it as a kid: We tried to figure out what the heck this weird game was about until giving up and moving on with life.
