Sakata Gorou Kudan no Renju Kyoushitsu (Japan)
Inside Sakata Gorou Kudan no Renju Kyoushitsu (Japan)
Sakata Gorou Kudan no Renju Kyoushitsu is a Japanese-exclusive Game Boy Color title that serves as an interactive tutorial for renju, a competitive board game derived from gomoku. Released sometime around the early 2000s, this cartridge was published by a now-obscure Japanese company - details on who actually developed it are sparse even among collectors. It's a straightforward educational game, not a hack or homebrew, but one of those niche titles that only saw a physical release in Japan.
Renju is played on a 15x15 grid, and the goal is to align five markers in a row, but with specific restrictions to balance the first-player advantage. In this game, you practice against a computer opponent that demonstrates opening patterns, forbidden moves, and strategic sequences. The interface is entirely in Japanese, so navigating menus requires either some language knowledge or a willingness to trial-and-error through the options. The core loop involves studying a position, then playing out the correct responses as taught by the on-screen instructor.
As a piece of retro gaming history, this title is primarily for renju enthusiasts or collectors of obscure GBC software. It doesn't offer arcade thrills or a story, but it faithfully teaches a deep game. If you have an interest in abstract strategy and want a portable way to learn renju, it's a neat artifact. Just be prepared for the language barrier and the slow, methodical pace of a digital lesson.
How to Play Sakata Gorou Kudan no Renju Kyoushitsu (Japan) Online
Getting Started
When the game boots, you'll see a title screen with Japanese text. Press Start or A to proceed. The main menu likely offers options like "Lesson" (レッスン), "Free Play" (自由対局), and "Options" (設定). Since this is a renju tutorial, begin with the lesson mode. You'll be shown a board position and a hint about which move to make. Use the D-Pad to move a cursor and press A to place a stone.
The core objective in renju is to get five stones in a row while preventing your opponent from doing the same. This game teaches special rules: the first player (black) cannot play certain patterns like double-threes or double-fours. Pay close attention to the on-screen instructions even if you don't read Japanese; the board visuals often make the lesson clear. If you make a mistake, the game will likely correct you and explain the proper move.
Because the entire interface is in Japanese, be patient. You can also try the free play mode to practice against a computer opponent of variable strength. Saving progress is usually handled by a battery inside the cartridge, so your lesson completion should persist as long as you don't reset. If you get stuck, consult online resources about renju rules to interpret the lessons better.
