  111.                 Anonymine is the "anonymous minesweeper" as I never had any
    112. 
    
  112.                 name for it, but I think "Anonymine" works just fine.
    113. 
    
  113.                 Back in December 2015 I was curious about creating an algorithm
    114. 
    
  114.                 for solving minesweeper, and then I needed an excuse for it
    115. 
    
  115.                 so I turned it into a terminal game that can be solved wihout any
    116. 
    
  116.                 guessing.
    117.

  118.             <p>
    119. 
    
  119.                 Do note that it runs in the terminal, so it may not be your cup of
    120. 
    
  120.                 tea.  Mouse input is usually supported, but only really useful in
    121. 
    
  121.                 hexagonal mode.

    124. 
    
  124.                 Being solvable without guessing is not its only feature,
    125. 
    
  125.                 it has many other unusual or even unique features:
    126. 
    
  126.                 the games are fully customizable and Anonymine seems to be the
