Minesweeper Challenge

Create a new public repository in your personal GitHub account and build a React version of the Minesweeper game. If you have the time, deploy this project to a publicly accessible service such as Heroku or Netlify. 

Re-create this application in ReactJS: https://agile-wildwood-75828.herokuapp.com/
  - It can be styled and themed however you like, as long as it preserves the core gameplay
  - Make sure to include a timer at the top to track the length of the game
  - Focus on correctly placing the mines and numbering the squares adjacent to the mines
  - Properly numbering edge blocks for the number of adjacent mines
  - The easy, medium and hard functionality is a bonus as it increases the difficulty ratio
  - Displaying the winning and losing states

We're going to focus on critiquing functionality and that you delivered a well tested version of the game.
