You win a game of Go by controlling more points than your opponent, counted as the empty territory you surround plus adjustments for stones and prisoners. The two main systems, Japanese and Chinese, usually name the same winner but count in slightly different ways.
Scoring feels intimidating to beginners because it happens after the fighting stops, when the board looks crowded. Once you know what counts and what does not, tallying a finished game takes only a couple of minutes.
When and How the Game Ends
The game ends when both players pass in a row, signaling that no useful moves remain. Before counting, both players agree on which groups are alive and which are dead.
Dead stones inside a living framework are removed and counted as prisoners for the surrounding player. There is no need to actually capture them on the board; agreement is enough, and disputes are settled by playing the position out.
Follow this sequence to score cleanly:
- Confirm both players have passed consecutively.
- Agree on and remove all clearly dead stones.
- Fill in neutral points called dame if using area scoring.
- Mark each player’s surrounded empty territory.
- Add prisoners or on-board stones depending on the system.
- Apply komi to White’s total and compare.
Neutral points that touch both colors, called dame, are worth nothing in Japanese scoring but worth filling in Chinese scoring.
Japanese Versus Chinese Counting
Territory scoring counts empty surrounded points plus captured prisoners. Area scoring counts empty surrounded points plus your own living stones on the board. The two feel different but rarely disagree on the winner.
| Feature | Japanese (territory) | Chinese (area) |
|---|---|---|
| Empty territory | Counted | Counted |
| Prisoners | Added to score | Not counted separately |
| Living stones | Not counted | Counted |
| Filling dame | No effect | Adds a point |
| Typical komi | 6.5 | 7.5 |
Beginners should use area scoring on a computer. It forgives sloppy prisoner-keeping because the software counts stones and territory directly, so you never lose track of captures.
Komi is the compensation White receives for Black moving first, and the half-point tail guarantees no ties. Without komi, Black’s opening advantage would make the game unfair on an empty board.
Deciding Which Groups Are Alive
Before any points are counted, both players must agree which stones are dead. A dead stone is one that cannot avoid capture even if its owner gets to move first, and it is removed as if it had already been taken.
A group is unconditionally alive when it has two real eyes, and dead when it cannot make them. Everything in between is settled by playing the position out or by mutual agreement. If players disagree, the standard fix is to resume play until the status is obvious.
Seki is a special case worth knowing. It is a mutual-life standoff where two groups share liberties and neither can capture the other without first putting itself in atari. Stones in seki live but their surrounded points usually count as neutral, so nobody scores territory inside the shared liberties.
Beginners often try to defend dead stones by adding more stones to a hopeless group. This only feeds prisoners to the opponent and, under territory scoring, fills in points that were already yours. Recognizing a lost group early and playing elsewhere saves those wasted moves for real profit.
Estimating the Score Mid-Game
Good players count roughly long before the game ends, because knowing whether you lead or trail should change how you play. A player who is ahead should simplify and avoid risks, while one who is behind must invade and complicate.
Divide the board into separate regions, estimate the territory in each, and add them for a running total you can update every few moves. You do not need an exact figure; even a rough count of who leads by how much is enough to steer your decisions.
Frameworks that are not yet sealed count for less than solid territory, so discount loose areas that your opponent could still invade or reduce. A wide moyo might look like fifty points but yield thirty after the opponent pokes at it, and honest counting accounts for that shrinkage.
Comparing your estimate against your opponent’s likely total tells you the plan. If you are ten points ahead with the board mostly settled, take the safe move every time and let the game close out. If you are ten behind, find the biggest reduction or invasion and accept the risk, because a quiet game only confirms the loss. Counting turns vague feelings about the position into concrete choices.
Counting in Practice
Estimating the score mid-game guides your decisions in the endgame. Break the board into separate regions, count each roughly, and compare running totals so you know whether to play safe or take risks.
Count territory in pairs of points to speed things up and avoid miscounts. Grouping empty intersections into twos or fives lets you total a large region at a glance rather than tapping every point.
The endgame is where careful counting pays off, because moves there are worth known amounts. A move that gains three points is bigger than one that gains two, so play the largest endgame moves first.
The very last stage of the game is filling the neutral dame points, which score nothing under territory rules but must be played out under area rules. Fill them without fuss, but stay alert, since a careless dame move can occasionally leave one of your own groups short of a liberty and open to a surprise capture.
Sente and gote decide the true value of endgame moves. A sente move forces a reply and effectively costs you nothing, so you can play several in a row, while a gote move ends your initiative. Prioritize your sente endgame moves, then take the biggest gote move, and your final margin will often improve by several points without any new fighting.
