Minesweeper is a classic logic puzzle games that was made popular by the Microsoft version Windows operating system. You can now play Minesweeper online on this website.
In Minesweeper there is a playing field of different sizes, in which mines are hidden in random places. Usually there are the following variations: 9x9 (=81) fields with 10 mines, 16x16 (=256) fields with 40 mines, or 30x16 (=480) fields with 99 mines. In the following picture we have a 9x9 field with 10 mines:
The goal of Minesweeper is to clear all the fields without hitting a mine. There is a hint for the user: for each field, it is displayed how many mines are in the surrounding fields. Based on these hints, the user is supposed to find out in which field there is a mine or not.
For example, if we look at the field inside the red circle in the image above, there is definitely a mine there. The three fields to the right of it indicate that there is exactly one mine in the adjacent fields. But the marked field is the only possibility, because it is the only field not yet uncovered.
