Minesweeper

Minesweeper is a single-player puzzle video game. The objective of the game is to clear a board containing hidden "mines" or bombs without detonating any of them, with help from clues about the number of neighbouring mines in each field.
In the game, mines are scattered throughout a board, which is divided into cells. Cells have three states: unopened, opened and flagged. An unopened cell is blank and clickable, while an opened cell is exposed. Flagged cells are those marked by the player to indicate a potential mine location.
A player selects a cell to open it. If a player opens a mined cell, the game ends. Otherwise, the opened cell displays either a number, indicating the number of mines diagonally and/or adjacent to it, or a blank tile, and all adjacent non-mined cells will automatically be opened. Players can also flag a cell, visualised by a flag being put on the location, to denote that they believe a mine to be in that place. Flagged cells are still considered unopened, and a player can click on them to open them.When the number of adjacent mines is equal to the number of adjacent flagged cells, all adjacent non-flagged unopened cells will be opened.
