Intermediate: 40 mines 16x16 grid

Game Objective
In Minesweeper, your goal is to uncover all the cells that do not contain mines, while avoiding clicking on any mines. Win the game by successfully marking all mines and revealing all safe cells.

Game Interface
Game Area: A grid of cells, each of which can be clicked or marked.
Mines: Hidden beneath the cells, not visible.
Numbers: When you click a cell that does not contain a mine, a number will appear showing how many of the 8 surrounding cells contain mines.
Flags: Used to mark cells where you believe a mine may be located.
Timer: Displays the time elapsed since the game started.

Basic Operations
Click a cell: Left-click a cell to uncover it. If the cell contains a mine, the game ends. If it does not contain a mine, the cell will display a number or automatically expand to reveal surrounding empty cells.
Mark a mine: Right-click (PC) or long press (mobile) a cell to place or remove a flag. The flag indicates that you believe there is a mine beneath that cell. Marking all the mines helps avoid accidentally triggering them.
Auto-Expand: If you click a numbered cell, and the number of surrounding flagged cells matches the displayed number, the surrounding cells will automatically expand (if they do not contain mines).

Game End
Victory: You win when all safe cells are uncovered or all mines are correctly marked.
Failure: If you click on a mine, the game ends and you will see the locations of all the mines.

Game Revival
Each game can be revived for free once. After that, revival requires a certain number of Coins. The first revival costs 3 Coins, the second costs 9, the third costs 27, and so on. You can revive up to 5 times in total.
