Most classic strategy games make you learn a dozen different pieces before you can play a single move. Go asks you to learn one. You place a stone on a line intersection, your opponent places a stone, and that repetition is the entire physical game. The rules that give it depth fit on a postcard, which is why people often say you can start playing go in about ten minutes.
That simplicity is also why the game confuses newcomers who arrive expecting chess-style complexity and instead find a nearly empty board and almost no rules to memorize. This guide walks through everything you need to sit down and play your first game, in the order that actually helps: what the game is called, the handful of rules that run it, how scoring decides the winner, and where to play for free tonight.
A note on where this comes from. I play shogi and live in Japan, where go boards sit in the same shops as shogi and chess sets, but I do not hold a go rank myself. So this is not a strong player writing from the inside. It is a curation of what the established English-language and Japanese beginner resources consistently teach, organized for someone starting from zero.
Go, Baduk, and Weiqi: One Game, Three Names
If you have searched around, you have probably seen the same game called by different names, and wondered whether they are variants. They are not. Go, baduk, and weiqi are one and the same game under three languages:
- Go is the Japanese-derived name, and the one most common in English. It comes from the Japanese igo.
- Weiqi (圍棋 / 围棋, roughly “the surrounding game”) is the Chinese name. China is where the game originated, more than two thousand years ago.
- Baduk is the Korean name, familiar to anyone who followed the game through Korean players or the drama and streaming scene.
The board, the stones, and the core rules are the same whichever word you use. Small differences exist between national rule sets, and we will get to the one that matters most to a beginner (komi) further down, but nobody is playing a fundamentally different game. Throughout this guide I will say “go,” and everything applies equally to baduk and weiqi.
The Whole Game, in Five Ideas
Here is go from top to bottom before we slow down and unpack each piece. If you internalize just this list, you can follow a game:
- Place stones on the intersections. Players alternate placing stones on the points where the grid lines cross. Black plays first. Once placed, a stone does not move.
- Surround to capture. A stone or connected group is captured and removed when the opponent fills all of its adjacent empty points (its “liberties”).
- Surround to score. Empty regions fully enclosed by your stones become your territory. More territory (plus captures, depending on the rule set) wins.
- Ko: no instant repeats. You may not make a move that recreates the exact board position from a moment ago. This stops endless back-and-forth recapturing.
- Pass and count. When neither player wants another move, both pass, the game ends, and you count up to find the winner.
That is the game. Everything below is detail and nuance layered onto these five ideas.
The Board and the Stones
The standard go board is a grid of 19 by 19 lines, giving 361 intersections. Smaller boards of 9 by 9 and 13 by 13 are common and widely used, especially for learning and quick games; more on why you should start small in a moment.
The single detail that trips up chess and checkers players is this: stones go on the intersections, the points where lines cross, not inside the squares. The empty crossing points are the currency of the whole game, so the board is best read as a mesh of points rather than a grid of cells.
Each player has a bowl of stones, one side black and one side white. Black moves first. Play then alternates, one stone per turn, and a placed stone stays exactly where it is for the rest of the game unless it is captured. There is no movement phase, no piece that slides or jumps. You are not maneuvering an army; you are gradually staking out the board.
You are always allowed to pass instead of placing a stone, though for most of a game you will not want to. Passing becomes important only at the very end, which is where we are headed.
Liberties and Capture
This is the one mechanic worth taking slowly, because everything else rests on it.
Every stone on the board has liberties: the empty intersections directly adjacent to it, up, down, left, or right (not diagonally). A lone stone in the middle of the board has four liberties. A stone on the edge has three, and a stone in the corner has just two.
Stones of the same color that sit next to each other along the lines are connected, and a connected group shares its liberties, counting all the empty points around the whole group as one pool. Connection is what makes stones strong, because a bigger group has more liberties to lose before it is in danger.
A stone or group is captured when its last liberty is filled by the opponent. Fill every empty point around an enemy group and it is removed from the board immediately; the captured stones come off and are set aside. That is the only way stones ever leave the board.
A practical picture: put a single white stone on an empty board and surround it on all four sides with black stones. The white stone now has zero liberties, so it is captured and lifted off. On the edge you only need three black stones to do the same job, and in the corner just two, since the edge of the board does part of the surrounding for you. This is why corners are the easiest place to make secure shapes, and why beginners are often told to start play in the corners.
Territory: How You Actually Win
Capturing stones is satisfying, but it is not the point of the game. The winner is decided by territory: the empty intersections you have surrounded and control.
At the end of the game, an empty point counts as your territory when every stone bordering that enclosed region is your color. You are effectively fencing off areas of the board with walls of your own stones, and the empty space inside your walls is yours. The player who has fenced off more points wins.
This reframes what those alternating stone placements are really doing. Each move is a small claim, either extending your own framework, reducing your opponent’s, or fighting over a contested boundary. Capturing enemy stones matters because it removes their walls and opens their would-be territory to you, but capturing is a means, not the goal. A game can be won with very few captures and a lot of quietly claimed space.
One consequence surprises new players: it is completely normal to leave much of the board empty. You do not need to fill territory with your own stones to own it. Filling in your own secure territory just wastes moves and, under some rule sets, even costs you points.
Ko: The One Repeat You Cannot Make
There is one rule that exists purely to keep the game from looping forever, and it is called ko (from the Japanese for “eternity”).
In certain positions, you can capture a single enemy stone, and your opponent could then immediately recapture your stone, returning the board to exactly where it was one move earlier. Left unchecked, the two of you could recapture back and forth without end.
The ko rule forbids this: you may not play a move that recreates the exact board position from immediately before. The player who was just captured has to play somewhere else first, at least for one turn, before coming back to retake the contested point. In practice this turns a ko into a small tactical negotiation, but as a beginner you only need to recognize the rule so you understand why the board sometimes says a natural-looking recapture is not allowed.
Illegal Moves and the Suicide Rule
Beyond ko, there is one more restriction to know about, and here the rule sets genuinely differ, so it is worth stating carefully.
Placing a stone that would immediately have zero liberties is generally not allowed. If dropping a stone onto a point would leave it (and its group) completely surrounded with no liberties, that is a self-capture, informally called a “suicide” move, and in many rule sets it is illegal.
The important exception, which holds across rule sets: if that same move captures enemy stones at the same time, it is fine. Removing the opponent’s stones gives your new stone liberties where the captured stones used to be, so the move is legal and often powerful. The forbidden case is only the pure self-capture that gains nothing.
Rule sets differ on how strictly they treat the pure self-capture case, and some treat the ban as optional, so if you ever read a rules document closely you may see it described differently. For a beginner playing online, this almost never comes up in practice: the client will simply refuse to let you play a move that has no effect but to remove your own stones, and that is all you need to know for now.
Ending the Game and Counting
A go game does not end in checkmate or when the board fills up. It ends by agreement.
When both players pass in succession, the game is over. You pass when you judge that there are no more useful moves, no more territory to gain or defend and no captures to make. Two passes in a row is the signal that both sides agree the boundaries are settled.
Then you count. The mechanics vary a little by rule set, but the beginner-level idea is consistent: the player who controls more of the board wins. Broadly there are two counting styles you will encounter:
- Territory scoring (used by the Japanese and Korean rules): you count your surrounded empty points, plus the stones you captured.
- Area scoring (used by the Chinese rules and others): you count your surrounded empty points plus your own stones left on the board.
The two methods usually produce the same winner, and as a beginner you do not need to master the arithmetic; online clients count for you automatically, right down to sorting out which groups are alive and dead. What matters conceptually is only this: more of the board under your control, by whichever count, is the goal.
Komi: Evening Out Black’s Head Start
Because Black moves first, Black has a real advantage. Go corrects for this with komi: a fixed number of points added to White’s score to compensate for going second. This is one place where the national rule sets diverge, and the numbers are worth knowing because you will see them on every online game:
- Japanese and Korean rules: komi is 6.5 points.
- Chinese, Ing, and AGA (American Go Association) rules: komi is 7.5 points.
The half-point is deliberate. Adding a fractional komi guarantees there can be no tie, since scores are otherwise whole numbers. The reason the two families use different figures comes down to territory scoring versus area scoring counting a move’s value slightly differently, so each system needs a different number to correct the same first-move edge. (China historically used other values, including 5.5, before settling on the current 7.5.) You do not have to think about komi at all while playing; the client applies it and reports the final margin.
Start Small: 9×9 Before 19×19
The full 19×19 board is the standard for serious play, but it is a poor place to learn, because a beginner cannot yet see the whole board as one fight and gets lost in the space. The path most commonly recommended for newcomers is to start on the 9×9 board, move up to 13×13, and only then take on the full 19×19.
The logic is straightforward. On a 9×9 board a game is over in a few minutes, and capturing, connecting, and the basic feel of surrounding territory all show up quickly and visibly. You get many complete games and fast feedback instead of one sprawling game you do not understand. The 13×13 board is a natural middle step, big enough to introduce the interplay between different areas of the board without the full 19×19 workload. By the time the large board feels comfortable, the fundamentals are already habits.
This progression is the common advice across beginner communities and teaching resources rather than an official mandate from any governing body, but the reasoning holds up: small boards teach the mechanics faster because you finish more games. If you own a physical board, the same one usually has a 13×13 or 9×9 grid available as well; online, you simply pick the board size when you start a game.
Reading the Ranks: Kyu and Dan
Go uses a ranking system that looks backwards at first glance, so it is worth a quick tour so you can read your own rating and other players’.
Ranks are split into two bands, kyu and dan:
- Kyu ranks are for weaker and improving players, and here the numbers run downward as you get stronger. Beginners who have just learned the rules are usually somewhere around 30 kyu. As you improve, the number falls: 30 kyu, then 20 kyu, then 10 kyu, and so on toward 1 kyu.
- Dan ranks begin once you pass 1 kyu, and here the direction flips: numbers run upward as you get stronger. Amateur dan ranks run from 1 dan up to around 7 dan.
So the ladder as a whole reads: 30 kyu (novice) → 1 kyu (strong amateur) → 1 dan → 7 dan (expert amateur). The single reversal at the kyu/dan boundary is the only quirk to remember. As a rough rule of thumb, one rank of difference corresponds to roughly one handicap stone, the head start a weaker player is given to make a game between mismatched players competitive. Professional players have their own separate dan scale running from 1 to 9, where the gaps between ranks are much smaller than among amateurs.
One caution for when you sign up somewhere: the traditional “beginners are about 30 kyu” figure is a general benchmark, not what any given site will show you on day one. Online servers each have their own logic for rating new accounts, and your displayed rank usually starts provisional and settles after you have played a handful of games, so do not read too much into the first number you see.
Where to Learn and Play Go for Free
You do not need to buy anything to start. The most beginner-friendly place to play go in English is OGS, the Online Go Server (online-go.com).
OGS is free and runs entirely in your web browser, with nothing to install. It supports multiple languages and, importantly for someone starting out, it bundles the things a beginner needs in one place: interactive tutorials that teach the rules, life-and-death puzzles to practice capturing and surviving, and AI bots you can play against at a wide range of difficulty levels so you are not thrown straight against experienced humans. When you are ready, it also has a large pool of human opponents for both live and slower correspondence games. Because the client enforces every rule and counts the board for you, it is nearly impossible to break a game by not knowing something, which makes it a forgiving place to fumble through your first few tries.
There are other well-known servers and apps in the go world, but OGS is the one I can point a beginner to with confidence: free, browser-based, and built to teach as well as to play.
But Isn’t This Basically Chess?
If you came here from chess, the honest short answer is: go and chess share a rectangular board and a two-player, no-luck, perfect-information structure, and almost nothing else. Chess is about coordinating unlike pieces to trap one king; go is about two players dividing an open space, with identical stones and no single decisive target. Which one is “harder,” and which suits which kind of player, is a longer conversation than this beginner guide should swallow, so I will leave the full comparison for its own article. For now, know that the skills do not transfer directly, and that is exactly what makes picking up go feel fresh even for a strong chess player.
If you enjoy this kind of Japanese strategy game, shogi (Japanese chess) is the natural next stop, and since it is closer to chess in feel, chess players often take to it quickly; there is a separate beginner’s guide to shogi on this site if you want to branch out.
Frequently Asked Questions
Is go hard to learn?
The rules are genuinely easy, which is why the “ten minutes to learn” line is not just marketing: place stones, surround to capture, surround to score, plus ko and passing. That is the whole rule set. Playing well is famously deep and can take years, but that gap between simple rules and deep play is the appeal, not a barrier to starting. You can play a complete 9×9 game the same day you learn.
Are go, baduk, and weiqi different games?
No. They are the same game under three languages: go (Japanese-derived, the usual English name), weiqi (Chinese), and baduk (Korean). The board and core rules are identical. Only minor rule-set details, such as the komi value and the counting method, differ between national traditions, and none of them change how you learn or play at the beginner level.
What board size should a beginner start with?
The 9×9 board. It is the most commonly recommended starting point because games finish in a few minutes, so you see capturing, connecting, and territory happen quickly and get many complete games in. The usual progression is 9×9, then 13×13, then the full 19×19 once the fundamentals feel natural.
What does komi mean?
Komi is a fixed number of points added to White’s score to make up for Black playing first. It is 6.5 points under Japanese and Korean rules and 7.5 under Chinese, Ing, and AGA rules. The half-point ensures a game can never end in a tie. You do not have to calculate it; online clients apply komi automatically.
Why do go ranks count downward?
Because there are two bands. In the kyu band (beginner to strong amateur) the numbers run down as you improve, from around 30 kyu toward 1 kyu. Once you pass 1 kyu you reach the dan band, where the numbers run back up, from 1 dan toward 7 dan for amateurs. The single flip at the kyu/dan boundary is the only oddity; roughly, one rank of difference equals about one handicap stone.
Where can I play go online for free?
OGS (online-go.com), the Online Go Server, is the most beginner-friendly free option in English. It runs in your browser with no install, has tutorials and puzzles, lets you play AI bots across a range of difficulties, and enforces the rules and scoring for you so you cannot break a game by not knowing something.
Your First Steps
You now have the whole game: stones on intersections, liberties and capture, territory to decide the winner, ko to prevent loops, and passing to end things. You know that komi balances Black’s first move, that ranks run down through kyu and back up through dan, and that 9×9 is where to begin.
The fastest way to make all of this real is to stop reading and play one small game. Open OGS, start a 9×9 game against a gentle bot, and let the board teach you what a paragraph cannot. You will lose the first several games, everyone does, and each one will teach you more about liberties and territory than another page of explanation could. The rules took ten minutes; the game is waiting.
