Looking at how the result of a game
is decided on the Go board



終局場面

The game may end as shown above, with both sides having completed their territories.
Well, which side do you think has won? Let's take a look.
We will see which territory has more points.



How big is Black's territory?
黒の陣地
Black's territory is made up of all the points marked x on the right. Each x is one point.
In total, Black's territory is 31 points.



How big is White's territory?
白の陣地
White's territory is made up of all the points marked x on the left.
In total, White's territory is 30 points.



Who won?
Black 31 points - White 30 points = Black 1 point more. Black won by 1 point.



How to count territory
Counting each point one by one is a lot of work.
The quick way to count is in multiples. White's territory (on the left) is 3x9 + 3 = 30. Black's territory is 3x9 + 4 = 31.
How about it? Counting this way is a lot simpler.
