The game of Hex has been invented in 1942 by Piet Hein, reinvented in 1948 by John Nash, got its name in 1952 from a commercial distribution by Parker Brothers, and has been popularized by Martin Gardner in 1957.
In Hex, the player to make the first move has a better chance of winning than the other player. This follows by the strategy stealing argument invented by John Nash. Hence the first player has an advantage in the game. To compensate for this advantage in the applet below, the central cell is blocked for the very first move.
