The objective of Google Minesweeper is to clear a rectangular board containing hidden mines without detonating any of them, with help from clues about the number of neighboring mines in each field. The game is won when all non-mine fields have been cleared, and lost when a mine is clicked.
Playing fullscreen allows you to have a more immersive experience by utilizing the maximum space available on your screen. This can be especially helpful for players who want to keep track of the entire board and make strategic moves.
