Description I have developed and tested the Minesweeper game. It is fully functional and ready for review.

Game Features

• A minesweeper game with its main goal to clear a rectangular board containing hidden "mines" or bombs without detonating any of them.
• Allow users to choose the grid size. According to which number of mines also changes.
• If the user opens a cell with a bomb, display a game over message.
• Allow user to play game again if he loses in a try.

Below are some Screenshots and video of the game-
