Go is a two-player strategy game where you place stones on a grid to surround more territory than your opponent. You win by controlling more empty points plus captured stones by the end, and the rules that make this possible fit on a single page.
The game began in China over 2,500 years ago and remains one of the deepest abstract games ever devised. The equipment is simple: a gridded board, black stones, and white stones. Everything else grows out of a handful of principles you can learn in ten minutes and study for a lifetime.
What You Need and How Play Starts
A full board has a 19×19 grid, but beginners should start on 9×9. Stones sit on the line intersections, not inside the squares, and once placed they never move unless captured.
Black always plays first, and players alternate one stone per turn. You may also pass instead of placing a stone. When both players pass consecutively, the game ends and you count the score.
Here is the fastest way to begin your first game:
- Set the empty board between both players and give Black the darker stones.
- Black places one stone on any intersection, aiming to sketch out a corner or side.
- White responds by placing a stone elsewhere, usually claiming a different area.
- Continue alternating, building loose frameworks rather than tight clumps.
- Capture enemy stones when you can, and defend your own groups.
- Pass when neither side can gain, then count territory to decide the winner.
The corners are easiest to hold, the sides come next, and the center is hardest. Strong beginners open in corners for exactly this reason.
Liberties and Capturing
Every stone or connected group has liberties, which are the empty intersections directly next to it along the lines. A group stays on the board only while it has at least one liberty, and it is captured the instant its last liberty is filled by enemy stones.
A single stone in the middle of the board has four liberties. On the edge it has three, and in the corner only two, which is why edge and corner stones are more vulnerable. To capture, you surround all of those points.
Never place a stone on a point where it would have zero liberties and captures nothing. That move is called suicide and is illegal in almost every ruleset.
Connected stones share their liberties as one unit, so linking stones along the lines makes them far harder to capture than scattered singles.
Territory and Winning
Territory is empty space your stones surround so that your opponent cannot make a living group inside it. At the end you add your surrounded empty points to the enemy stones you captured.
The comparison below shows how the two main scoring systems differ.
| Scoring method | What you count | Common region |
|---|---|---|
| Territory (Japanese) | Empty surrounded points plus prisoners captured | Japan, Korea |
| Area (Chinese) | Empty surrounded points plus your stones on the board | China, most apps |
Both methods usually produce the same winner, so pick one and stay consistent. White receives extra points called komi, typically 6.5 on a full board, to offset Black’s first-move advantage. The half-point also guarantees there are no draws.
Special Rules You Should Know
Two extra rules prevent the game from breaking down. The first bans suicide, meaning you cannot place a stone that would immediately have no liberties unless that same move captures an enemy group and frees up space.
The second is the ko rule, which stops players from recapturing a single stone right back and repeating the exact board position. After your opponent captures one stone in a ko shape, you must play a move elsewhere before you are allowed to take it back. This keeps a small corner skirmish from looping forever and adds a layer of bluffing to the game.
Passing is also a genuine move, not a forfeit. Late in the game, when every remaining move would only lose points, both players pass and proceed to counting. Deciding when nothing useful is left takes practice, so early on you can keep playing small moves until the borders are clearly settled.
One more habit helps enormously: recognize when a group has two eyes. Two separate enclosed empty points make a group permanently safe, because your opponent can never fill both at once. Chasing eyes for your own groups and denying them to your opponent is the heart of the middle game.
Building Good Habits Early
New players tend to make two mistakes: crowding stones together and chasing every capture. Spread your early stones across corners and sides to claim more of the board with fewer moves.
Resist the urge to answer every enemy move locally. If your opponent plays a small move in one corner while a huge area sits open elsewhere, the bigger area is usually more valuable than defending a few points. Learning to leave a local fight for a larger opportunity separates thoughtful players from reactive ones.
Think about influence, not just captures. A wall of stones facing open space projects power over a whole region even before a single point is enclosed. Trading a small capture for a strong outward-facing position is often the better deal.
When a group looks threatened, count its liberties and compare them with the enemy group attacking it. Whoever fills the other’s last liberty first wins that fight, so an extra liberty decides many close races.
Play a dozen games on 9×9 before moving up to 13×13, then 19×19. The smaller board teaches fighting and life-and-death quickly, while the big board adds the grand strategy of framework building.
Do not worry about losing at first, because early losses are how the patterns sink in. Review each finished game by asking where a group died or a large area slipped away, and you will improve faster than by simply playing more. Once capturing and counting feel natural, you are ready to study opening theory and the shapes that keep groups alive.
