Andantino is normally played upon an infinite field of hexagonal cells. But for this implementation a hexagonal field of 10-cell sides will be used.
 
Black has considered to have played on the central cell, White must follow with a placement to any empty cell which is adjacent.
 
Each player must then play a Stone to an empty cell which is adjacent at least two other Stones of any color.
 
A player wins by either forming a straight row of five friendly Stones, or completely surrounding one or more opponent Stones with friendly Stones.
