About 7moku

Table of Contents

7moku is a two-player abstract strategy game on a 19×19 board, similar to the popular game Gomoku (also called five-in-a-row).

Each turn a player places a 2×2 tile that contains two X's and two O's in one of six fixed patterns.

A player wins by forming seven or more consecutive symbols of their own (horizontal, vertical, or diagonal).

A single placement can complete a line for both players at once - a mutual win.

Despite simple rules, 7moku creates very complex positions. Perfect play remains an open research problem.

Leaderboard & Scoring

7moku features global leaderboards where players can compete in Ranked vs Player and eligible Ranked vs Bot games. Local bot Practice and Self-Play games can be saved to history, but they do not change ranked totals.

Score Calculation Formula

Score = (Wins × 3) - (Losses × 1)

Example: If you have 10 wins and 3 losses, your score is (10 × 3) - (3 × 1) = 27 points.

Saved Profiles

7moku is free to play, and you can play without saving a profile. A saved profile lets your name, avatar, eligible game history, and leaderboard progress stay with you when you come back or play on another device.

1. Get on the Leaderboard

To keep ranked play fair, only saved profiles can appear on leaderboards. You can still play without saving a profile; those games stay on this browser and do not count toward ranked standings.

2. Keep Your Profile

Saving your profile keeps your player name and avatar available when you return. You can also use the same profile on another phone or computer.

3. Fair Play & Anti-Cheat

Every ranked game is checked before it counts. Self-Play and local bot Practice can be useful for learning, but they do not increase your ranked score.
