How to Play Gomoku for Absolute Beginners

If you have never played Gomoku, you are in for a treat. It is one of the simplest board games to learn and one of the hardest to master — which is exactly why it has survived for two thousand years. This guide gets you from "what is this?" to your first finished game in about five minutes.

What is Gomoku, in one sentence

Gomoku (Japanese for "five stones") is a two-player game where you try to place five of your stones in a row — horizontally, vertically, or diagonally — before your opponent does. That is the entire goal. If you want the longer version, see what Gomoku is and how you win.

What you need to play

You only need two things: a board and stones of two colors.

• The board. A standard Gomoku board is a 15x15 grid of intersecting lines (225 points). You place stones on the intersections, not inside the squares.
• The stones. One player uses black, the other white. On trygomoku.com the computer handles the colors for you.

The basic rules

1. Black moves first. The first player places a black stone anywhere on the board.
2. Players alternate. After black, white places one stone, then black, and so on. You cannot pass and you cannot move a stone once placed.
3. Win by five-in-a-row. The first player to get an unbroken line of five stones (horizontal, vertical, or diagonal) wins immediately.
4. Draws happen. If the board fills with no five-in-a-row, the game is a draw.

That is it. Two rules — alternate, and make five — cover 95% of casual games. The deeper wrinkles (like Renju forbidden moves) only matter in tournaments; we cover board setup and basic rules separately.

A quick note on "exactly five"

In standard free-style Gomoku, five in a row wins — and six or more also counts as a win in casual play. If you are coming from games like Connect Four, the big difference is the board: a 15x15 grid gives enormous room for strategy, which is why Gomoku beats Connect Four for depth.

Your first winning idea: control the center

Beginners almost always win or lose based on one habit — where they play early stones. Dropping your first stone near the center gives it the most room to grow in every direction. Edges trap you. Once you internalize that, the next step is learning a few openings; our top 10 Gomoku openings is the natural follow-up.

Common beginner mistakes to avoid

The single most common error is playing only on your own lines and forgetting to block your opponent. If they already have three in a row, you usually must block — or you lose on their next turn. We wrote a full list of common Gomoku mistakes and how to fix them for exactly this.
