All Questions
What is gomoku?
Gomoku is a two-player strategy board game where players take turns placing black and white stones on a grid. The goal is to be the first to form an unbroken line of five stones in any direction — horizontal, vertical, or diagonal. It's also called Five in a Row, Gobang, or Omok.
Is gomoku the same as Go?
No. Although they use the same board and stones, gomoku and Go (Weiqi/Baduk) are completely different games. In Go, the goal is to surround territory by placing stones strategically. In gomoku, the goal is simply to make a line of five. Gomoku is much easier to learn and faster to play — think of it like the difference between checkers and chess. Same-looking pieces on the board, totally different game.
Is gomoku the same as Connect Four?
No. Connect Four uses a vertical 7×6 grid where pieces fall due to gravity — you can only place in the lowest open spot in each column. Gomoku is played on a flat 15×15 grid where you can place stones on any empty intersection. Gomoku offers much more strategic depth because you have full placement freedom. Think of Connect Four as gomoku with a gravity constraint bolted on.
Is Five in a Row the same as Gomoku?
Yes. "Five in a Row" is the English name; "Gomoku" is the Japanese name. Same game, same rules, different words. Other names you might see: Gobang (older English, from Japanese "goban" meaning Go board), Omok (Korean), Wuzi Qi (Chinese).
What does "gomoku" mean?
It's Japanese for "five stones in a row" (五目並べ, gomoku narabe). That's literally what the game is — five in a row. The Japanese named it after what you do, which is honestly better than some game names out there.
How long does a game of gomoku take?
A typical casual game lasts 3–10 minutes. On a smaller 9×9 board, games are even faster (2–5 minutes). Tournament games on a 15×15 board can last 15–30 minutes, especially between evenly matched players who keep trading threats without a decisive break.
What board size does gomoku use?
The standard gomoku board is 15×15 intersections (same as a Go board, but smaller than Go's 19×19). However, 9×9 and 13×13 boards are also common for casual and beginner play. You can play on a 19×19 Go board too — just ignore the outer edges.
Who goes first in gomoku?
Black always goes first. This gives Black a slight advantage, which is why the Renju variant adds restrictions on Black to balance the game. In casual play the advantage is small enough that it doesn't matter much — but at the competitive level, it's everything.
Is gomoku a solved game?
Yes — it has been mathematically proven that with perfect play, the first player (Black) can always win on a 15×15 board. However, this proof (by Victor Allis in 1993) involves strategies too complex for humans to execute perfectly. In practice, games between skilled players are still competitive and interesting. And competitive play uses Renju rules (with forbidden moves for Black) which levels the field completely.
What is Renju?
Renju is the professional variant of gomoku developed in Japan. It adds restrictions on Black (the first player): Black cannot make double-threes, double-fours, or overlines (6+ in a row). White has no such restrictions. Renju also uses 26 designated opening patterns. The name means "connected pearls" in Japanese — a deliberate upgrade from the original name "gomoku" which just means "five in a row."
Can I play gomoku online for free?
Yes — you can play gomoku right on our website. No download or signup required. Choose between playing against our AI opponent (with adjustable difficulty) or challenge a friend in local two-player mode.
What is the best first move in gomoku?
The center of the board is the strongest first move. Starting in the center gives you the most flexibility to build lines in all four directions (horizontal, vertical, and both diagonals). Any other first move weakens your position. This isn't a tip — it's basically a rule.
Where did gomoku originate?
Gomoku originated in China — the exact century is debated, but it predates written records. It was later adopted in Japan (where it became Renju, with added forbidden-move rules) and Korea (where it's called Omok). Today it's played competitively worldwide under RIF tournament rules.
What are the basic strategies for beginners?
Start in the center, learn to create double threats (forks), keep your lines open (avoid blocked ends), and balance offense with defense. Don't spend all your moves blocking your opponent — build your own threats too. The biggest beginner mistake is playing purely reactively instead of building something.
How many stones do you need to play gomoku?
Technically, you need enough stones to fill the board (225 for a 15×15 grid). In practice, games never come close to filling the board — you'll use maybe 40–80 stones per game. A standard Go set comes with 181 black and 180 white stones, which is more than enough. For casual play, anything with two colors works: coins, buttons, M&Ms, dried beans.
Do you place gomoku stones on the squares or the intersections?
On the intersections (where the lines cross), not inside the squares. This is the same as Go. It's the single biggest thing that confuses new players who are used to chess or checkers where pieces go inside the boxes. On a 15×15 board you have 225 intersections to play on, not 225 squares.
Can you play gomoku on a Go board?
Yes, 100%. Gomoku and Go use the exact same equipment — same wooden board, same black and white stones. The only difference is that Go boards are 19×19 while standard gomoku uses 15×15, but you can play gomoku on a 19×19 board and just use the center area. If you own a Go set, you already own a gomoku set.
What is VCF in gomoku?
VCF stands for "Victory by Continuous Four." It's a sequence of forcing moves (all fours) that guarantees a win because your opponent has no choice but to respond to each one. VCF is the most powerful tactical concept at the intermediate level — learn it and you'll beat most casual players consistently.
Does a line of six count as a win in gomoku?
It depends on the rules. In standard gomoku, only exactly five counts — six or more (an "overline") does not win. In free-style gomoku, an overline does count. In Renju, an overline is forbidden for Black (you lose if you make one) but allowed for White. This detail trips up a lot of new players.
What is Gobang?
Gobang is an older English name for gomoku, from the Japanese word "goban" (碁盤) meaning "Go board." It was more common in British English and older books. These days most people say "gomoku" or "five in a row," but you'll still see "gobang" in some contexts. Same game, different name.
Is gomoku good for kids?
Absolutely — it's one of the best strategy games for kids. The rules take 30 seconds to learn, games are short (especially on a 9×9 board), and the "five in a row" concept is intuitive. It teaches pattern recognition, planning ahead, and the idea that defense matters as much as offense. No violence, no reading required, no complicated setup. Just stones on a grid.
How do I get better at gomoku?
Three habits: (1) Play against <a href="/play/" class="text-amber-700">AI on increasing difficulty</a> and don't move up until you win consistently. (2) Review your games afterward — specifically, find the moves where you missed a forcing move or a double threat. (3) Read the <a href="/strategy/beginner/" class="text-amber-700">strategy guide</a> and practice one concept per session (today: forks, tomorrow: VCF). Deliberate practice beats mindless playing every time.
What are the gomoku world championships?
The Renju International Federation (RIF) has been running world championships since 1989, roughly every two years. Countries like China, Japan, Estonia, Russia, and Sweden dominate. Fun fact: Estonia — population 1.3 million — has won multiple world titles. The competitive scene is small but serious, and online play has been growing steadily.
