The rules are simple: The first player to capture a stone or group of stones wins. Once a player loses a stone, he or she must resign. If no stones are captured during the game, the winner is the one with the most territory. \n\nKeep in mind that this changes the way you play completely. For example, a group that has a single two territory eye is alive because the other player would have to sacrifice a stone -- and therefore the game -- to kill the group. Naturally, there is no such thing as a ko or a snapback.\n\nTournament starts once the maximum number of players have signed up.\n\nConditional moves enabled, provisional players welcome.\n\nSorry about the McMahon bars set to 20-10k.
