Gomoku Compared with Go, Connect Four, and Tic-Tac-Toe
Gomoku is often confused with other familiar board games because the names and equipment overlap. It uses black and white pieces on a grid like Go, asks players to build a line like Connect Four, and is easy to explain through the same basic idea as Tic-Tac-Toe. The games are not interchangeable. Their boards, legal moves, win conditions, and strategic questions are different.
Quick answer
Choose Gomoku when you want a fast connection game with free placement on a flat grid. Choose Go when you want captures, territory, and a long positional game. Choose Connect Four when you enjoy gravity and a compact 7-column board. Choose Tic-Tac-Toe when you want the simplest three-in-a-row introduction.
At-a-Glance Comparison
| Feature | Gomoku | Go | Connect Four | Tic-Tac-Toe |
|---|---|---|---|---|
| Main goal | Make the agreed five-in-a-row condition | Control territory and capture stones | Make four in a row | Make three in a row |
| Common board | 15x15; smaller boards are common for practice | 19x19; 9x9 and 13x13 for teaching | 7 columns by 6 rows | 3x3 |
| Placement | Choose any empty intersection | Choose an empty intersection; captures can remove stones | Drop a disc into a column; gravity chooses the slot | Mark any empty square |
| Captures | No | Yes | No | No |
| Typical first lesson | Place stones, block threats, complete five | Liberties, captures, territory, and passing | Drop pieces and read vertical tactics | Alternate turns and spot a fork |
Gomoku vs Go
Gomoku and Go are the closest visual relatives in this comparison. Both use stones on intersections, and a 15x15 Gomoku board can look like a smaller Go board. In Gomoku, stones normally remain on the board and the first player to complete the agreed line wins. In Go, stones are surrounded and captured, and the final result depends on territory and scoring rather than a line.
The way you read the board changes as well. Gomoku is a forcing game: look for an immediate win, an immediate block, an open three, an open four, or a move that creates multiple threats. Go is a positional game: compare groups, liberties, influence, territory, and whether a local exchange helps the whole board. A good Go move does not need to create a line, and a strong Gomoku move does not need to enclose territory.

Gomoku vs Connect Four
Both games are connection games, but Connect Four limits every move to a column and uses gravity. The position grows from the bottom upward, so choosing a column can support or block several vertical, horizontal, and diagonal lines at once. Gomoku has no gravity: you place a stone directly on any empty intersection of a flat grid.
Connect Four is compact and easy to set up as a physical family game. Gomoku provides a much larger placement space and usually asks players to inspect more possible lines. Connect Four strategy is closely tied to turn order and column height; Gomoku strategy is closely tied to open space, line shape, and forcing replies.
The two games can both be good for a short game night, but a Connect Four rack is not a substitute for a Gomoku grid. See Gomoku vs Connect Four for the differences in gravity, board geometry, solved-game claims, and beginner expectations.
Gomoku vs Tic-Tac-Toe
Tic-Tac-Toe is the simplest member of the line-forming family. Every legal square is visible on a 3x3 board, and perfect play leads to a draw. Gomoku keeps the idea of making a line but expands the board and the target to five, creating more room for attacks, blocks, and competing threats.
Tic-Tac-Toe is a useful teaching bridge: children can learn alternating turns, direct wins, blocks, and forks before moving to a larger grid. It is not accurate to describe Gomoku as only “big Tic-Tac-Toe,” though. The number of candidate lines, the importance of open space, the rule variants, and the first-player balance make Gomoku a separate strategy game.

Which Game Is Hardest?
There is no single difficulty scale because the games demand different skills. Tic-Tac-Toe has a small state space and is easy to solve. Connect Four has fewer legal actions per turn but requires careful calculation through gravity. Gomoku has many open intersections and tactical patterns. Go has a large strategic and scoring system that takes longer to learn.
Choose Gomoku if you enjoy
- Short games with a visible winning target
- Free placement rather than gravity
- Pattern recognition and forcing threats
- Moving from beginner boards to deeper strategy
Choose another game if you prefer
- Go: captures, territory, and global balance
- Connect Four: columns, gravity, and a compact board
- Tic-Tac-Toe: a very short introduction to line games
- Any of them: learning with a friend rather than studying alone
A Good Starting Route
- Play one or two Tic-Tac-Toe games if you need to learn the idea of turns, blocks, and forks.
- Try Gomoku on a 9x9 board and state the active rule set before the first move.
- Move to 13x13 or 15x15 when you can consistently check immediate wins in all four directions.
- Read about Renju before using formal opening or forbidden-move terms in a casual game.
- Try Go or Connect Four separately if their central idea—territory or gravity—sounds more interesting.
Frequently Asked Questions
Is Gomoku the same as Go?
No. Gomoku is a five-in-a-row connection game without ordinary captures. Go is a territory and capture game. They share stones and intersections but not the objective.
Is Gomoku the same as Connect Four?
No. Connect Four uses a vertical 7x6 rack and gravity; Gomoku uses a flat grid where a player can choose any empty intersection.
Is Gomoku just a bigger Tic-Tac-Toe?
They share a line-forming concept, but Gomoku uses a much larger board, a five-stone target, more rule variants, and a deeper tactical decision space.
Can I use a Go board to play Gomoku?
Yes, if both players agree on the Gomoku rules. A 19x19 Go board gives more intersections than the 15x15 board commonly used for formal Gomoku and Renju.
