Professional Mahjongg Gokuu

Overview

Professional Mahjong Gokuu is a riichi mahjong game developed by Chat Noir and published by ASCII for the Famicom Disk System in Japan on December 25, 1986.

A successor to Chat Noir's earlier Professional Mahjong, Professional Mahjong Gokuu presents the game of mahjong in the standard "table view" (rather than the "grid view" of most earlier mahjong games).

As the name and later box art implies, the game pits the player against several characters from the classical Chinese novel Journey to the West, with the player implied to be the mythical figure Son Gokuu.

The game was later ported to Japanese computers, with the NEC PC-98 version released in 1987, the X68000, FM-7, MSX, and NEC PC-88 versions released in 1988, and the FM Towns version released in 1989. These versions add a ranking system for the player, which rises and falls depending on match results. The game received multiple sequels, building on both its game engine and its use of characters and themes from Journey to the West.
