About 60,000,000. Most of these are in Korea, China and Japan.
There are more than 70 countries who have official organisations and take part in the annual World Amateur Go Championship.
Yes, there are about 1,000 in China, Japan, Korea and Taiwan with a few emerging in the last year or so in North America and Europe.
We think that there are about 10,000 active Go players in Britain, and many more who have some recognition of the game. Some 15,000 people have been taught to play in the last three years. The British Go Association has about 500 registered members.
There are over fifty Go clubs in Britain. Our web site has a map showing these , saying when and where they meet.
About thirty Go tournaments are held in Britain each year. The British Go Association web site has a list of these . Most are one-day events held at weekends, with the first prize going to the strongest player to win all his or her games, and other prizes to players who do well playing against other players of similar strength. Some longer tournaments, and some teaching days, are also held. We also hold online tournaments over the Internet.
There is no established “World Go Championship”. Japan, Korea and China each have a number of Go titles, which are competed for each year, reported in their news media and are well funded. The winner of the Kisei (the most prestigious Japanese tournament) wins 42,000,000 yen (worth about £250,000).
As of 2014 many people regard the Korean Lee Sedol as the world’s strongest player, as he has been dominating for several years in many events and especially in the Fujitsu Cup, which can be regarded as the top “international title”.
He or she can be found in our page describing the British Championship .
A comparison can be seen here .
Most graded players have “kyu” ratings, (like the coloured belts in Judo) from 30 kyu for a beginner up to 1 kyu. Stronger amateur players have “dan” ratings, (like black belts in Judo) with a 1 dan being slightly better than a 1 kyu, up to the strongest amateurs who are rated 6 dan. China, Japan and Korea also assign professional ratings. A 1-dan professional is about the same as a 6-dan amateur, and the world’s best players are 9 dan. The intervals between professional grades are about three times as close together as those between amateur kyu and dan grades.
This table is approximate.

Computer programs have been surprisingly bad at playing Go until very recently.
A top club player can usually beat most programs. The top program is at top-level professional level (AlphaGo from Google DeepMind as of March 2015). See our Computer Go history  for more information.
