The game was scored wrong!

Every game against another human player ends in a “remove dead stones phase”. The sole purpose of this phase is for both players to agree which groups are alive with points / alive in seki / dead. And while the computer predicts the result for convenience it can on occasion be wrong, and it is the responsibility of the players to check the result.
You can change the status of a group by clicking / shift+clicking on it. Only when everything is marked correct should you press the accept button. Moderators are not obligated to change a result of a game both players agreed on.
In a game against bots there is no “remove dead stones” phase, to prevent cheating, because our bots are not yet clever enough to be able to argue their case. If your game against a bot was scored wrong, feel free to contact a moderator, who will in time annul the result.
