Gomoku

Classic five-in-a-row board game

Gomoku (Five in a Row)

Gomoku is a classic strategic board game. Two players take turns placing pieces on the board, and the first to connect five pieces in a line wins the game.

Game Rules

The game is played on a 19×19 grid board, with Black playing first. Players alternately place their pieces on the intersections of the grid. The winner is the first player to form an unbroken line of five stones horizontally, vertically, or diagonally.

Example: Black and White players taking turns on intersections

Basic Strategies

Center Control

Controlling the center area is a key winning strategy. Placing stones in central positions not only provides more attacking directions but also limits your opponent's development space. It's recommended to compete for center control in the early game.

Multiple Threats

Creating multiple attack points is a powerful tactic. By forming double threes, double fours, and other multiple threats, you can force your opponent into difficult defensive positions. This strategy often leads to decisive advantages.

Defensive Awareness

While attacking, maintaining defensive awareness is equally important. Pay special attention to your opponent's three and four-stone formations, and prevent them from forming threats. Good defense not only resolves crises but also creates counterattack opportunities.

Diagonal Tactics

Diagonal attacks are often the most overlooked and hardest to defend against. Utilizing diagonal lines can create powerful offensive positions. Pay attention to diagonal development possibilities during your setup, as they can lead to unexpected victories.

Frequently Asked Questions

What are the basic rules of Gomoku?

Gomoku has simple but engaging rules:
• Played on a 19×19 grid board
• Black plays first, then players alternate turns
• Stones are placed on intersections
• Win by forming an unbroken line of five stones:
- Horizontally (→)
- Vertically (↓)
- Diagonally (↘ or ↗)

Is there any restriction on where I can place my stones?

In standard Gomoku, you can place your stones on any empty intersection on the board. There are no restrictions on placement, unlike some variants like Renju which have special rules for the black player.

What's the best opening strategy?

The center area is strategically important. A common opening strategy is to place your first stone near the center of the board. This provides maximum flexibility for developing your position and creates more opportunities for forming winning patterns.

What are the common patterns I should watch for?

Key patterns to watch for include:
• Open Four: Four stones in a row with empty spaces at both ends
• Double Three: Two separate formations of three stones that could become Open Fours
• Blocked Four: Four stones in a row with one end blocked
These patterns are crucial for both attacking and defensive play.

How do I defend against my opponent's threats?

Defense is crucial in Gomoku. Always check for your opponent's potential winning moves. Block their attempts to create Open Fours immediately. When facing multiple threats, try to find moves that both defend and create your own opportunities for attack.

Is there a time limit for each move?

In casual games, there's typically no time limit. However, in competitive play, players often use time controls. Our online version includes an optional timer setting that you can adjust according to your preference.

What's the difference between Gomoku and other similar games?

While Gomoku shares similarities with games like Connect Four and Renju, it has its unique characteristics. Unlike Connect Four, pieces don't fall but are placed freely. Renju adds extra rules for the black player to balance the first-move advantage, while standard Gomoku keeps rules simple and symmetric for both players.
