Computer Olympiad 2020

The 2020 Computer Olympiad will be held online. You must register by November 23, and the awards ceremony is December 15.

We are delighted to be using the Ludii software to conduct the Olympiad competitions. “Ludii is a general game system designed to play, evaluate and design a wide range of games, including board games, card games, dice games, mathematical games, and so on.” There are over 300 games currently available on the Ludii site. For many of them, you have the chance to build the world’s best AI! Ludii has an appealing graphical user interface, as well as many useful tools for the game competitor.

Note that for some competitions, if all the competitors agree, an established non-Ludii site can be used for the Olympiad competition. For example, a few popular games have established servers that facilitate computer-versus-computer play. It may be more convenient for competitors to use a site they are familiar with, rather than having to build a Ludii interface.


In recent Olympiads, the following games have been contested. If your favorite games is not on this list and you know that there are at least two potential entrants, please contact us and we can add a new game to the Olympiad.

Amazons, Block Go, Breakthrough, Chinese chess, Chinese checkers, Chinese dark chess, Clobber, Connect6, Dice Shogi, Dots and Boxes, Draughts/Checkers, EinStein Würfelt Nicht, Go, Gomoku, Hex 11×11, Hex 11×13, Kyoto Shogi, Mahjong, Minishogi, Nonogram, Othello, Outer-Open Gomoku, Shogi, Surakarta, etc.
