A field is divided into squares.
Squares either contain concealed bombs or are empty.
Aim of the game: deduce which squares contain bombs through observation, logic and, occasionally, a little luck.
The player interacts with the field by marking squares to indicate their assumed contents and clicking (entering) squares to reveal their actual contents.
The game is won when the player correctly identifies all squares containing concealed bombs by marking each with a flag.
The game is lost should the player click on a square containing a concealed bomb.
