About Gomoku Guide

Why This Site Exists

If you search "play gomoku online," most results are either generic gaming portals where gomoku is buried among hundreds of other games, or sites with a playable board but zero explanation of how to actually get better. We built Gomoku Guide because we couldn't find a single English-language site that combined a working game with serious strategy content and proper rules explanations.

We explain practical opening ideas, common patterns, and the difference between casual Gomoku and formal Renju. Tournament opening procedures can change, so players should use the current Renju International Federation rules for competition requirements.

Five-in-a-row has been played for at least four thousand years across East Asia, and the game carries cultural weight that most online resources ignore. This site treats that heritage as a reason to explain things properly: what the rules actually are, why formal Renju added restrictions that casual play skips, and how the game connects to the broader family of connection games (Go, Pente, Connect Four) without pretending they are interchangeable.

Who Is Behind Gomoku Guide

Gomoku Guide is a solo project run by a small team of board game enthusiasts. The person who built the site is a full-stack developer with a decade of experience in web and backend engineering. The motivation is straightforward: I wanted a site I could trust when I searched for a specific Gomoku question and found the same three ad-heavy pages every time.

The content is written and maintained by the same team that built the game. There is no content syndication, no AI-generated filler, and no affiliate-driven app roundup that changes with the highest paying advertiser. Every strategy claim on this page has been checked against the RIF rules or a primary source before publication. If you spot an error, the contact page is open.

The site is not affiliated with the Renju International Federation, Apple, GamePigeon, Supabase, or any other service mentioned here. Those are cited as sources or referenced as platforms, not as partners.

How We Keep Guides Accurate

Gomoku Guide is an educational site, not a tournament authority. We distinguish the casual exact-five rules used by this site, free-style house rules, and formal Renju competition rules. Rules, historical claims, and computer-science topics are reviewed against primary material where it is available. Pages with technical or historical claims show a review date and link to sources.

The game engine uses minimax search with alpha-beta pruning at three plies for the Hard difficulty level on 9×9 and 13×13 boards. This is not the strongest engine published; it is strong enough to punish casual play and weak enough that a patient beginner with the right opening patterns can win occasionally. The design choice is deliberate: the goal is to help players learn to read positions, not to be the hardest bot on the internet.

What You Will Not Find Here

No public leaderboard. No anonymous matchmaking. No chat, no user accounts, no social graph. The online room is a private link — you create it, you share it, you play it. There is no reason to build a login system for a two-player board game, and we are not going to add one to collect email addresses or serve a personalized ad feed.

The site does run Google Analytics and Google AdSense. Both are disclosed in the privacy policy. No other third-party trackers are loaded. No email, no chat, no social features, no app store funnel — just the game, the rules, and the strategy content that explains how to actually play better.

We also do not rank apps in a fixed "top 10" list. The apps page explains how to evaluate a listing yourself rather than telling you which one to download. Store listings change; a leaderboard that was accurate in January is wrong by March. We would rather teach you the method than sell you a stale list.

What We Believe About Gomoku

Gomoku is one of the oldest two-player strategy games still in active play, and it deserves to be taken seriously in English-language content. Most of what you will find when you search for "gomoku" in English is a 30-second explainer that treats the game the same way a board-game portal treats chess: a throwaway item in a list of 200 games. That is a disservice to a game with a four-thousand-year cultural history and a rich body of tournament-level study in formal Renju.

Our position: a good Gomoku site should explain the actual rule variants (exact-five, five-or-more, formal Renju with its Black-only forbidden moves), show you how the game connects to its cousins (Go, Pente, Connect Four), and give you a working board you can use today without signing up for anything. We think a focused, honest site beats a gaming portal with 500 half-documented titles.

We also believe the cultural origin matters. Five-in-a-row developed independently in China, Japan, and Korea over centuries. The Chinese name Wuziqi, the Japanese name Gobang, and the Korean name Omok all refer to the same core game with local rule variants. A serious site should name all three and explain when to use which. Most English-language content does not.

How the Site Is Built

The entire site is a static Astro project — every page is a plain HTML file served from a CDN. There is no backend, no database, no user account system. The game board is a TypeScript class running entirely in your browser. When you play a local game or a private online room, the data never touches a server we operate; the online room uses third-party realtime infrastructure and the connection is peer-to-peer in spirit, not a centralized game server.

The strategy and rules content is written in English by the same developer who built the game. We check rule claims against the RIF rules and historical claims against primary sources before publication. If a claim cannot be sourced, we say so explicitly rather than presenting it as fact.

The site is free to use. It runs on Google AdSense for basic hosting and CDN costs. There is no premium tier, no paywalled content, and no "pro" features locked behind a subscription. Everything on this site is available to everyone who can open a browser.

What We're Not

We're not a gaming portal with 500 games. We don't have public leaderboards, random matchmaking, or chat. We do offer local play and private friend rooms. This is a focused resource: one game, covered thoroughly. If you want to learn why the center opening is strongest, what VCF means, or how Renju's double-three ban changes the game — you're in the right place. If you want to play battle royale gomoku with strangers, not yet.

Content Sourcing Policy

Strategy content on this site is original writing, not scraped from forums or translated from Japanese-language blog posts. Opening analysis is based on standard Renju opening theory documented in published sources. We link to primary sources whenever a claim goes beyond basic rule explanation. The glossary and history page each list their specific sources.

If you find a strategy claim that conflicts with what you learned from a different source, the issue is usually which rule set each source is using. Formal Renju (with its opening procedure and Black-only restrictions) and free-style casual play produce different "best first moves." Check which rule set applies before drawing conclusions.
