Gomoku vs Go vs Connect 4

People often mix up gomoku with Go or Connect 4 because the boards look similar. Here is a side-by-side look at how gomoku compares with three related games — and where each one shines.

Gomoku vs Go

Versus Go (Weiqi)

BoardGomoku: 15×15 intersections
Go (Weiqi): 19×19 intersections

CapturesGomoku: No captures — stones stay
Go (Weiqi): Stones are captured and removed

Win conditionGomoku: Five in a row
Go (Weiqi): Surround more territory

Learning curveGomoku: Minutes to learn
Go (Weiqi): Months to play well

Game lengthGomoku: 5–20 minutes
Go (Weiqi): 30–120+ minutes

Go is a deeper, longer game of territory; gomoku is a tighter puzzle of lines.

Gomoku vs Connect 4

Versus Connect 4

BoardGomoku: 15×15 grid on paper or screen
Connect 4: 7×6 vertical plastic frame

First moveGomoku: Black chooses any point
Connect 4: Red must drop from the top

GravityGomoku: No gravity — free placement
Connect 4: Pieces fall to the bottom

GoalGomoku: Exactly five in a row
Connect 4: Exactly four in a row

Connect 4 borrows gomoku’s “connect the line” idea but adds gravity and a tiny board, making it a quick kids’ game.

Gomoku vs Connect 6

Versus Connect 6 (六子棋)

GoalGomoku: Five in a row
Connect 6 (六子棋): Six in a row

Forbidden movesGomoku: Renju restricts Black
Connect 6 (六子棋): No forbidden moves

First-move edgeGomoku: Moderate, balanced by Renju
Connect 6 (六子棋): Strong — first player drops two stones

Connect 6 gives the first player a bigger edge by letting them place two stones per turn, which is why it skips forbidden moves.

Bottom Line

If you want a game you can learn in a minute yet keep studying for years, gomoku is the sweet spot: simpler than Go, deeper than Connect 4, and faster than both.
