Gomoku vs Connect Four — Comparison
Five in a row vs four in a row — two connection games compared.
Gomoku vs Connect Four — both are connection games about lining up pieces, but they play very differently.
If you like lining things up in a row, both games deliver — but at very different scales.
Side-by-Side Comparison
| Feature | Connect Four | Gomoku |
|---|---|---|
| Goal | 4 in a row | 5 in a row |
| Board | 7 columns × 6 rows | 15 × 15 intersections |
| Placement | Gravity (pieces fall to lowest open slot) | Free (any empty intersection) |
| Directions | Horizontal, vertical, diagonal | Horizontal, vertical, diagonal |
| Players | 2 | 2 |
| First player advantage | Yes (solved — first player wins) | Yes (very strong; rules exist to Counter) |
| Complexity | Low-Medium | Medium-High |
| Game length | 5-10 minutes | 10-30 minutes |
| Time to learn | 2 minutes | 5 minutes |
| Origin | USA, 1974 (Milton Bradley) | Japan/China (ancient, hundreds of years) |
The Key Differences
1. Placement Rules (The Biggest Difference)
Connect Four: Pieces DROP into columns. Gravity controls where they land. This limits your choices to 7 possible moves per turn (one per column).
Gomoku: Place your stone on ANY empty intersection. On a 15×15 board, that’s up to 225 possible first moves. This freedom creates enormously more strategic depth.
2. Board Size and Scale
| Metric | Connect Four | Gomoku |
|---|---|---|
| Total spaces | 42 | 225 |
| Possible first moves | 7 | 225 |
| Avg. game length | 20-30 moves | 40-60+ moves |
| Possible game states | ~4.5 trillion | Astronomically more |
Gomoku’s larger board means more room for complex patterns, traps, and long-range threats.
3. Winning Line Length
Connect Four’s 4-in-a-row on a small board makes double threats relatively easy to create. Gomoku’s requirement of 5-in-a-row on a huge board makes winning much harder — you need longer chains of threats.
4. First Player Balance
Both games favor the first player, but they handle it differently:
| Game | First Player Advantage | How It’s Addressed |
|---|---|---|
| Connect Four | Strong (solved: first player wins with perfect play) | Usually not addressed (casual game) |
| Gomoku | Very strong | Renju rules, swap rules, or opening restrictions |
Renju is the competitive variant of Gomoku that restricts the first player from certain patterns (double-threes, double-fours) to balance the game.
Strategy Comparison
| Strategy Concept | Connect Four | Gomoku |
|---|---|---|
| Center control | Critical (column 4 is key) | Important but less dominant |
| Double threats | Primary winning tactic | Primary winning tactic |
| Reading ahead | 4-6 moves for strong play | 6-10+ moves for strong play |
| Pattern recognition | Moderate | High (many patterns to learn) |
| Blocking | Easy (only 7 columns) | Hard (many directions to track) |
| Opening theory | Minimal | Extensive (studied positions) |
Which Should You Play?

Skill Progression
If you enjoy connection games, here’s a natural progression:
- Tic-Tac-Toe — 3 in a row (trivially solved, but teaches the concept)
- Connect Four — 4 in a row with gravity (solved, but strategically rich at human level)
- Gomoku — 5 in a row with free placement (deep strategy)
- Renju — Gomoku with competitive balance rules
- Go — territory control (the ultimate abstract strategy game)
Each step adds complexity and depth.
