However, the server doesn't ever know if a game is over, nor who won.

That is left as an exercise to the players. The losing player should resign.

 

Note from Richard

 

This is due to the difficulty of determining the live/dead status of groups of stones. In fact, recently, I was looking at a game and completely missed a seki.

Someday, I hope to add an end-game phase where, after both players have passed, they begin a "nominate... accept/reject" phase where one player nominates a group of stones that he feels are dead. and the other player accepts or rejects that nomination.

Lather... Rinse... Repeat...

again... once both players have passed (meaning there are no more dead groups, only live groups and groups in seki), then (and only then) could the server determine the score.

This is essentially how the IGS servers work (IIRC).
