Go Quest



GoQuest is an online go server, developed by Yasushi Tanase, where people can play 9x9, 13x13 and 19x19 (only available at "peak times") go against each other and against AI. All games have a komi of 7.

The time limits are:

  • 9x9 3min+1s/move
  • 13x13 5min+3s/move
  • 19x19 5min+3s/move


There were 38,451 registered players on 20 Sep 2016 (now 31,762 in 2019) including professionals from Japan and Korea. The top players are (19 Feb 2019):

  • 9x9 Linbee, 9D (The strongest 9D 9x9 player in 2019. The other 9D is Spaceman who is much weaker than Linbee)
  • 13x13 Jinbeshark, 10D
  • 19x19 (New feature, insignificant number of games played so far)


An unusual feature is that fuseki names are displayed when they are played. Some of these are listed on the 9x9 Openings/Discussion page.


The server has inspired an ebook.


The server can be accessed using an Andoid app from the [ext] Google Play store, the [ext] Amazon App store and on [ext] iTunes. It is also possible to access the server through a [ext] web browser.

SiouxDenim I enjoy playing quick 9x9 and 13x13 games on this server, especially as it is always hard to get a game on these sizes on KGS. My general comments:

  • Chinese scoring is used. Many players pass prematurely, before the dame are filled and points in seki claimed.
  • Scoring is done automatically and is occasionally wrong. If the status of a group is even slightly complicated, play it out. Chinese rules mean it costs you nothing.
  • There are many players who refuse to pass if you have less time than them. If you meet them, be prepared to make your groups extra solid and then be ready to hit 'pass' very quickly. This tactic does of course occur in real life blitz games, but seeing your opponent move his hand over the board gives a little warning as to where a move is going to be made.
  • Many users have complained that the 9x9 ranking system is out of alignment with real life ranks. My personal view is that tournament 19x19 games and online blitz 9x9 games are very different and so one's rank could also be very different for each. Further, the sheer number of games played on this server mean that it is probably now the authoritative source for World 9x9 rankings.
  • At some point in Feb 2017 the rating required to be 1d was changed from 1750 to 1700. I find this disappointing as it devalues the 1d it took me 1000 9x9 games to achieve.

Monteo This server's ranking system will become the standard raking system for the global 9x9 go community. The Elo score of 1700 is already the proper rating required to be 1D. Nowadays a greater number of very strong shodan are playing 9x9 go at the sever and it has recently been harder for genuine kyu players to reach 1D. We can see a lot of dan players there have Elo scores below 1700 but quite hard to beat if you are not playing well enough.

SiouxDenim Everywhere else, an Elo of 2100 is 1d (e.g. AGA and EGF ranking systems). Why was 1700 chosen for GoQuest? It would usually represent 4k.

Monteo Everywhere else, there are probably a lot of 9 dan players. At GoQuest only two players have reached 9 dan (as of 2019-07-26). Moreover, this is the worldís most popular 9x9 ranking system. The rating for shodan is not too suppressive like other systems. This system is standard. Being 1 dan GQ means you are 1 dan Igowin Pro (R1700).
