Unfortunately physical Hex sets are difficult to come across. The Parker Brothers’ version was published the 1950s; unsurprisingly, it’s difficult to find a copy. Aside from that there are a handful of websites offering sets, although the prices are rather high.
Fortunately you don’t need a board to play Hex! Since stones never move a game can be played with pen and paper. I’ve included printable Hex boards in the appendix. You can print these out and mark your moves on the page with different colour pens. Red and Blue are the traditional colours (for Black and White respectively). Conveniently, if both players write their move numbers down inside each move then the resulting page serves as a complete record of the game played.
Besides pen and paper there are also websites for playing Hex. Most websites where you can play Hex offer it alongside other board games. There are two varieties of online play: “real-time” and “turn-based.” In real-time games players make moves within a few minutes or less. Players will have to remain present until the game is over. In turn-based games players typically have a day or more to make a move. Players typically log in once a day or so and move in all their games. This also allows a player to spend more time analyzing their move if they should choose to.
Turn-based Little Golem is probably the most popular place to play Hex online, and it’s where I typically play. There are a large number of players, and Hex can be played at sizes 11×11, 13×13 and even 19×19, with 13×13 being the most popular. The great thing about Little Golem is that you can review every game ever played there. Most of the examples in this book come from Little Golem games.
For real-time play, the most popular sites are currently igGameCenter and PlayOK. hexy.games is a new website with real-time play of Hex and the related game Havannah.
