Igo: Kyuu Roban Taikyoku is an adaptation of the board game called Go, a board game that originated in East Asia, and is possibly the oldest board game invented. There are both black and white stones, one of each controlled by a player, and the goal of the game is for one player to place more stones on the board than their opponent. Igo: Kyuu Roban Taikyoku is actually a port of the game Microgo1, which was released for a few home computers. The original game was programmed by English programmer Allan A.C. Scarff, who also contributed the algorithms for the Famicom versions.

Though the game of Go is usually played on a 19x19 grid, Igo: Kyuu Roban Taikyoku is played on a 9x9 grid, as it is aimed toward beginner players. There are also five levels of difficulty ranging from very easy AI to very hard AI. The game also gives the players a ninja of their respective stone color, but they serve only as cosmetic and comedic purposes.

Igo: Kyuu Roban Taikyoku was released originally on the Disk System in April 1987, and subsequently received a standalone Famicom release later the same year. However, there are minimal, if any differences between the two versions.

Because Igo: Kyuu Roban Taikyoku is an early game, it leaves a lot to be desired in the audio department. There are only four songs. The main in-game tune is only 12 seconds long, and its high-pitched instrumentation can possibly leave some listeners going for the mute button. However, the rest of the songs are nice and upbeat. There is even a special song that plays if the player idles for too long.

Though the game was originally released on the Famicom Disk System, it only uses the 2A03 for music, and does not take advantage of the expansion audio of the Famicom Disk System's RP2C33.

The music was written by Hiroshi Suzuki, who would go on to score many games for BPS through Goblin Sound. It is unknown how exactly he entered the music data, but seeing this is an early title, he most likely wrote in either 6502 assembly, or some custom form of Music Macro Language.

There are no in-game credits, but a full staff list exists in both the Famicom Disk System and Famicom versions of the manual.

Though Kazuya Takahashi programmed the sound driver used in BPS's games, this game uses a custom driver, and Takahashi is only listed as a programmer, so it is unknown if he programmed the driver used in this game as well.
