AI techniques used in Hex
Programs with AI
There are several computer programs which play Hex.
|MoHex||Linux||As of 2010, the strongest available Hex program. It uses the UCT-Monte Carlo approach and is developed at the University of Alberta by Philip Henderson, Broderick Arneson and Ryan Hayward.|
|Hexy||Windows||The second strongest program available. It was the first program to use virtual connections and was champion of the 5th Computer Olympiad in 2000.|
|Wolve||Linux||Gold medallist of 2008 Computer Olympiads.|
|Six||Linux, Unix, Windows||by Gábor Melis.|
|Hexilla||Java||By Jonatan Rydh, released in October 2009.|
|Hex||Android||By Five Factorial, released in January 2017. It uses MoHex engine on Expert level.|
No known programs for the Mac are available. There is a work around by using an emulator such as BlueStacks that allows Android programs to be run.
|Mongoose||By Yngvi Björnsson, Ryan Hayward, Mike Johanson, Morgan Kan, and Nathan Po.|
|Queenbee||By Jack van Rijswijck. Won silver at the London 2000 CGO.|
|Hexy||iPhone||Despite using the same name, this program has no relation to Hexy. It was released in November 2008, offers an AI opponent; the AI appears to be a custom design and hasn't been rated. As of 26 December 2019 it is no longer available.|
|Hexatious||iPad, iPhone||Released in August 2009, appears to offer a stronger AI than the iPhone Hexy app (in particular, Hexatious easily beats the other iPhone app in head-to-head competition). As of 26 December 2019 it is no longer available.|
|Hex Nash||iPad, iPhone||Released February 2011, no AI but supports online asynchronous play and local play. As of 26 December 2019 it is no longer available.|
Non playing programs
- HexGui is a graphical user interface designed by Broderick Arneson ("ab"). It can be used as an interactive game board to try out plays and variations, and it can also be used as a front end for any computer Hex program that can communicate via GTP. It works well as a front-end to MoHex. HexGui can read and write the Smart Game Format. An up-to-date version of HexGui is available from GitHub.
Reviewing and Editing Programs
- JHex by Kevin lets you analyse a game, and databases of games.
- KHex by David King is a tool for reviewing games. Very well suited for sharing commented games (it exports games in Smart Game Format).
- KHex18 by David King is an online app for reviewing games, which can read LittleGolem game text.
- GTP is a text-based protocol for interacting with Hex software. It is based on the Go Text Protocol, and allows Hex software to interact with Hex strategy engines.
- The Smart Game Format (SGF) is a file format for storing annotated game trees. The format nor only stores a sequence of moves comprising a game, but can also contain variations (several different games played out from the same position), as well as comments on every move in the game.

The International Computer Games Association also has some information on Hex. They organize an annual Computer Olympiad, which also covers Hex.
