JavaScript Mine Sweeper

While trying to get a good grasp of JavaScript/CSS, I decided to implement Mine Sweeper.

I tried to use the standard colors for the numbering and standard icons for mines/flag/unknown.

 

I’ve identified the 5 states that any particular cell could be and designed a finite state machine for one cell

  • S is for initial state
  • B is for bomb
  • F is for flag
  • ? is for unknown
  • C is for clear
Finite State Machine for one Mine Sweeper cell
Finite State Machine for one cell

 

This is what the final product looks like
