A customizable reimagination of the game we all know and love: Minesweeper.

How gameplay works:

• The player's objective is to reveal all tiles that are safe.
• A tile can be safe, or contain a mine.
  
• A revealed tile displays the number of mines present in it's neighbors, if this number is greater than zero.
• Tiles are considered to be neighbors if any of their sides or edges touch.
  
• If a tile is revealed and none of it's neighbors contain mines, it will automatically reveal it's neighbors.
• The player may place and remove flags from tiles to avoid accidentally uncovering these.
• A tile cannot be revealed as long as it is flagged.

What is different about sandbox?

• Customizable grid dimensions:
  Set the grid to an arbitrary size. 50x20? Go for it! 300x1? Sure, why not?  (Currently limited to 500x500 for no real reason)
• Customizable mine fraction:
  1% mines? Sure thing! 99%? knock yourself out!
• Save progress:
  Continue where you left off after closing the game.
