The '''Computer Olympiad''' is a multi-games event in which computer programs compete against each other. For many games, the Computer Olympiads are an opportunity to claim the "world's best computer player" title. First contested in 1989, the majority of the games are [[board games]] but other games such as [[Contract bridge|bridge]] take place as well. In 2010, several puzzles were included in the competition.

Developed in the 1980s by [[David Levy (chess)|David Levy]], the first Computer Olympiad took place in 1989 at the [[Park Lane Hotel]] in [[London]]. The games ran on a yearly basis until after the 1992 games, when the Olympiad's ruling committee was unable to find a new organiser. This resulted in the games being suspended until 2000 when the [[Mind Sports Olympiad]] resurrected them. Recently, the International Computer Games Association (ICGA) has adopted the Computer Olympiad and tries to organise the event on an annual basis.

In the year 2024, parody website [https://www.mike-row-soft.com Mike Row Soft] added an image of the [[Olympics]] with various [[Linux]] distros displayed inside the circles, and color-matched.

==6th–10th Olympiads (2000–2004)==
After an eight-year hiatus, the Computer Olympiad was revived by bringing it into the [[Mind Sports Olympiad]]. The chess competition was a special event, since it was adopted by the [[International Correspondence Chess Federation|International Correspondence Chess Association]] (ICCA) as the 17th [[World Microcomputer Chess Championship]] (WMCC 2000). The 5th Olympiad was in 2000 at London's [[Alexandra Palace]]; the 6th, in 2001 at Ad Fundunm at [[Maastricht University]]; the 7th, in 2002 in [[Maastricht]]; the 8th, in 2003 in [[Graz]]; and the 9th, in 2004 in [[Ramat Gan]]. The 7th Olympiad was adopted by the ICCA as the 10th [[World Computer Chess Championship]] (WCCC), and the 8th was held in conjugation with both 11th WCCC and the 10th [[Advances in Computer Games Conference]]. Because of this, no medals were awarded for the two chess events. The 9th was held in conjugation with WCCC and the [[Computers and Games 2004 Conference]]; no medals were awarded to the two chess events. [[Jonathan Schaeffer]] and [[J. W. H. M. Uiterwijk]] were the tournament directors.

Bridge is a [[trick-taking card game]] for four players.

Bridge participation in the Computer Olympiad was largely discontinued when in 1996 the [[American Contract Bridge League]] established a new official World Computer Bridge Championship, to be run annually at a major bridge tournament.  Starting in 1999, that event is now co-sponsored by the [[World Bridge Federation]].
