HY 2

HY 2 is a two-player game played on a regular hexagonal board (all sides of equal length) of any size, initially empty. The two players, Red and Blue, take turns placing their own stones onto unoccupied cells of the board, one stone per turn. Red starts. You can’t form a path connecting opposite sides of the board unless by doing so you win the game. A corner cell is considered to be part of both of the sides adjacent to it. Each player will always have a placement available. To win, you must form a group of your stones such that: 1. At least two of the group's stones occupy perimeter cells. 2. The shortest perimeter path that includes all of the perimeter cells occupied by the group's stones comprises more than half of the perimeter. Design notes HY 2 was preceded by Hexagonal Y. HY 2 is just a different way of ensuring that a winning Y will form with no possibility of a deadlock.
