Go Rules

This site follows the Japanese rules of Go. To end a game, press “Pass” from the “Menu” and make sure both sides (you and the AI) pass. This site allows you to undo moves, so feel free to use that feature if you are unsure about a move.

About the Tutorial System

The tutorial system is custom-built in JavaScript. AI tools such as ChatGPT were used during development. The Game Boy Advance game “Hikaru no Go” also strongly influenced the design.

About the Practical Go Course

This course operates using the open-source Go viewer "BesoGo." On this site, the user interface has been independently modified to improve usability.

AI Match System

AI matches use the “GNU Go” engine. This engine is used without modification. AI strength is adjusted for each character.
The AI may not handle special positions (such as complex seki, triple ko, or eternal life) correctly. Please keep this in mind.

About the Translation

This site was originally created in Japanese and translated into English using generative AI. As a result, some phrasing may sound a bit awkward. We have prioritized accurate Go terminology, but we cannot guarantee perfect accuracy. Thank you for your understanding that some information may be inaccurate.
