In the ancient board game Go, the final score is determined by counting each player’s stones on the board, the empty points they surround (territory), and the prisoners they have captured from the opponent. This method, known as territory scoring, rewards both solid board presence and successful attacks.
Territory is defined as any empty intersection that can be reached only by a single colour’s stones when the board is examined without crossing the opponent’s stones. Captured stones, called prisoners, are removed from the board and added to the captor’s score, reflecting the tactical advantage gained.
The widget below automates this calculation: you enter the counts of stones, territory, and prisoners for each colour, and it instantly returns the net score, helping players verify their end‑game tally quickly and accurately.
