About Gomoku (Five in a Row)
Gomoku, also known as Five in a Row or Gobang, is an ancient abstract strategy game that originated in Japan over a thousand years ago. The name comes from the Japanese words for “five” and “board game piece.” The goal is straightforward: be the first player to place five of your pieces in an unbroken row — horizontally, vertically, or diagonally — on a 15×15 grid. Despite its simple rules, gomoku offers profound strategic depth with intricate attack and defense patterns that take considerable study to master.
Gomoku is closely related to Go and is traditionally played on the same 19×19 board. The game gained widespread popularity in East Asia before spreading globally through the internet. The key tactical concepts include the four (four in a row with one open end), the three (three in a row with both ends open), and the double three — two simultaneous threats that cannot both be blocked, creating a guaranteed win for the attacker.
Various rule variants address the inherent advantage the first player (Black) has. Most competitive versions restrict Black’s opening moves to prevent an automatic win with perfect play. Learning to set up and defend against double-three attacks is the gateway to advanced gomoku play.
How to Play Gomoku
Two players alternate placing their pieces (black and white stones) on the intersections of the grid. Black always goes first. The first player to create an unbroken line of exactly five pieces in any direction wins. Some rule variants require exactly five in a row — overlines of six or more do not count for Black — to balance the first-player advantage.

Frequently Asked Questions
Is gomoku free to play on Rare Pike?
Yes, completely free. No registration or download needed.
What is the difference between gomoku and Go?
Both are played on grid boards with stones, but they are very different games. In Go, the goal is to surround territory; in gomoku, the goal is simply to place five pieces in a row. Go pieces are never removed in gomoku.
Why does Black have a bigger advantage in gomoku?
The first player has the initiative and can force wins with optimal play without restrictions. Competitive rules like Renju restrict Black from playing certain double-three and double-four patterns to balance the game.
What is a double three in gomoku?
A double three is a simultaneous position where a player creates two open-ended rows of three pieces at once. Since the opponent can only block one, the other becomes a guaranteed win on the next move.
