Read a review of version 10.
The most recent computer go engine (12.0) is available in Japan, as
"AI IGO", with a
Japanese user interface for Windows or Macintosh. This is one
of the best selling go programs in Japan.
You can play against "The Many Faces of Go" on the internet
at IGS or KGS. It uses the name "ManyFaces" on both servers. The
version on IGS might talk to you.
Go ratings for amateurs are on a scale that starts around 25 Kyu
for beginners, goes to 1 kyu, then 1 dan, then 6 dan or so for the
strongest players. Most people who are serious about studying the game, and
have stronger players to play with, can get to 10 kyu in about
a year, and 1 dan in 3 to 5 years. American (AGA), Japanese, and
NNGS ratings are a little weaker than ratings in China, Taiwan,
Korea, Europe, and IGS.
Go programs are hard to rate accurately, since they each have areas
of strength, and other areas of weakness compared to people. So
far no one has made a go program that can learn from its mistakes, so
once someone has played a few games against a program, they can
change the handicap against it by several stones.
The older Many Faces of Go version 11 has a 6 Kyu diploma from the Japanese Nihon-Ki-in,
based on test games against rated Japanese players
and some sample play against a 9-dan professional. It had a rank on the NNGS server of 10 kyu.
Many Faces verison 12 maintains a rank of around 2 Kyu on KGS, based on
hundreds of games against many different players.
Known Bugs, Incompatibilities, and issues in Version 12.0
- Installation must be in the default folder
- Installation fails on 64 bit windows.
Known Bugs, Incompatibilities, and issues in Version 10.0
- On some Windows-NT machines the 256 color graphics don't work, so
the game appears in only 16 colors. A patch is available to fix
this bug. Download it here.
- If you add commentary to a move, then immediately try to
guess the next move and guess wrong, the commentary is lost. To work
around, after adding commentary, just go back a move then forward
again before guessing the next move.
Popular suggestions for future versions. No guarantees that any
of these will be in the next version, but this is what I am thinking
about working on.

- Stronger go engine - I will do this for sure.
- Much bigger joseki library from japanese joseki dictionary.
- More pro games, especially from Korea.
- Add context menus for right button mouse clicks.
I've been working on this go engine for a long time, and it has
appeared in many earlier products:
- Between 1981 and 1987, various versions were given away free
to friends, running on HP-1000, Vax, and PA-RISC. An old HP-UX free
version is still available on some web sites, called xgo.
- September, 1988.
Cosmos, the Computer Go Partner for the IBM-PC. One upgrade version
of Cosmos was
released in 1990.
- The source code for the final version of Cosmos was given to the
Spec benchmark committee,
and is now 099.GO, one of the SpecInt95
benchmark suite. Hundreds of compiler writers around the world
are tuning their compilers to make my go program run faster :-)
Spec's description of the program.
The Many Faces of Go had five earlier releases (7.0x, 8.0x, 9.0x, 10.0 and 11.0)
Igowin is a free 9x9 only Windows-95/98/NT version of Many Faces of Go, that
plays fast, tracks your go strength as you improve, and learns from
its mistakes so it never loses the same way twice. It includes the
full Many Faces of Go tutorial, and an on-line manual with lots of
information about the game. Download it here.
Igo was a 9x9 only DOS version of Many Faces of Go, with a deliberately
dumber engine. It includes the Go tutorial from The Many Faces of
Go, and has the same great graphics. It is free, and intended to
help beginners learn the game.
Go simulator was a version of the first release of The Many Faces of Go,
released in Europe with a 3 language manual and box.
An early version of The Many Faces of Go was sold in Korea, with
a Korean box and manual.
A version for EO and Intel Penpoint OS handheld computers.
Go programs based on the Many Faces of Go engine are on sale in Japan
and Korea, for IBM-PC, Mac, and Sony Playstation.
