Gomoku vs Connect Four: What's the Difference?
Gomoku and Connect Four are both strategy games where you try to form a line of pieces — but the similarities end there. Here's a complete comparison.
Quick Answer
Gomoku is played on a flat 15×15 grid where you place stones freely on any intersection. Connect Four is played on a vertical 7×6 grid where pieces drop due to gravity. Gomoku offers far more strategic freedom and depth.
Side-by-Side Comparison
| Feature | Gomoku | Connect Four |
|---|---|---|
| Board | 15×15 flat grid | 7×6 vertical grid |
| How pieces are placed | Any empty intersection | Drop into a column (gravity) |
| Win condition | 5 in a row | 4 in a row |
| Game length | 3-10 minutes | 2-5 minutes |
| Strategy depth | Very high | Moderate |
| Skill ceiling | Very high | Moderate |
The Gravity Difference
This is the most important distinction. In Connect Four, you can only place a piece at the lowest available position in a column — gravity pulls it down. This limits your options to just seven columns each turn. In gomoku, you can place a stone on any empty intersection. Every turn, you're choosing from dozens of possible moves instead of just seven.
Strategic Depth
Gomoku has significantly more strategic depth than Connect Four. Professional gomoku has 26 designated opening patterns, while Connect Four has just 7 possible first moves. Gomoku's larger board creates far more tactical patterns — double threats, forks, and multi-directional attacks. According to game theory research, both games are "solved," but gomoku's complexity makes the first-player advantage much harder to exploit in practice.
Which Game Should You Play?
Choose gomoku if you want deep strategic thinking, a game that rewards study and improvement, and something with a competitive scene.
Choose Connect Four if you want a quick, casual game that's easy to teach children, with simpler decisions each turn.
Frequently Asked Questions
Is gomoku harder than Connect Four?
Yes, gomoku is significantly more complex. The larger board (225 positions vs. 42) and 5-in-a-row goal create exponentially more possible game states and strategic possibilities.
Can I use a Connect Four board to play gomoku?
No — they use completely different boards. Gomoku requires a flat grid where you place stones freely, while Connect Four uses a vertical frame with gravity-based drops.
