Gomoku Strategy: 10 Tips to Win More Games
Gomoku looks like a game of luck until you play someone who sees two moves ahead. These ten habits are what separate casual players from players who win three games in four. None of them require memorising openings.
1. Play the centre early
The centre point has the most lines running through it: four directions, each of which can become a winning line. Stones on the edge have fewer ways to grow. Unless you are deliberately building a defensive wall, open near the middle.
2. Count threats, not stones
A “threat” is a shape that wins next move unless answered. A seven-stone cluster with no threats is worth less than three stones that make an open three. After every move, ask: what does my opponent threaten now, and what do I threaten?
3. Learn the four shapes that matter
| Shape | What it looks like | Danger |
|---|---|---|
| Open three | Three stones with both ends open | Becomes an open four next move — must be answered |
| Broken three | Three stones with a gap inside | Often overlooked; can become a four |
| Open four | Four stones with both ends open | Unblockable — you win next move |
| Double threat | Two threats created by one stone | Usually decisive, because only one can be blocked |
4. Block the most advanced shape
When your opponent has two threats, block the one that wins sooner: an open four beats an open three. Beginners block the nearest stone; stronger players block the shape that ends the game.
5. Make fours with both ends open
A four that is open at both ends cannot be stopped — your opponent can block one end and you win at the other. A four with only one open end is merely a threat, which is why extending a three through a closed end is often a wasted move.
6. Prefer forcing moves
A forcing move gives your opponent only one sensible reply, so it dictates the pace. Fours force a block; open threes force a defence. If you can chain forcing moves, you control the game while your opponent reacts.
7. Look along the diagonals
Rows and columns are easy to see. Diagonals are where games are lost. After placing a stone, sweep the two long diagonals through that point before you look anywhere else.
8. Attack and defend with the same stone
The best moves do both: they block your opponent's line while extending your own. Placing a defending stone that also creates a three is worth roughly two ordinary moves.
9. Do not fill your own lines
Every stone you add to a line shortens the space available in that direction. A common beginner mistake is to build a long row that has no room left to become five. Leave yourself room to grow.
10. Play against a stronger opponent
Strategy guides teach shapes; games teach timing. Play the gomoku board on this site on Medium until you win regularly, then move to Hard. Losing to a computer that never gets tired is the fastest way to learn which of your moves were actually threats.
The one-sentence summary: gomoku is won by making two threats when your opponent can only answer one, so every move should ask “what does this create, and what does it stop?”
