Super MineSweeper

Q: What should I do after entering the game?
Answer: Try clicking on the grid. Be careful not to hit the mines.

Q: How do I know if a square is a mine?
Answer: When you click on a grid, it will display a number indicating the number of mines within a 3*3 range. Based on these numbers you can calculate which tile has a mine.
Once you determine that a grid is a mine, you can right-click on that grid to put a flag on that grid to remind yourself that it is a mine.

Question: What is a stone?
Answer: Stones cannot be clicked. Nothing works, it just sits there quietly.

Q: What is sight distance?
Answer: When you turn on sight range 2, the number displayed in the grid will be the number of 5*5 mines, not 3*3.
When you turn on sight distance 3, it will be 7*7.
