Here’s my attempt at a condensed version of the rules:
There are five players, each with their own color, each trying to claim the largest part of the 9x9 board.
The players submit their moves simultaneously at the same time each day (some moves may take 48 hours instead of 24 hours, if one or more of the players needs some extra time). For instance, after the first day we may have 5 stones on the board already. There are some details about how collisions are handled, and how captures are calculated, but I think for that you have to read the full rules.
The arbiter (@yebellz) will post the updated game board in this thread after each move, along with information about collisions and captures, so I think those details will become clear as the game progresses, even without studying the rules closely.
The players may discuss and share information, form alliances etc. either in this public thread or in private 1-on-1 threads. However, no promises are binding, and a player can betray another whenever they want. In the end, it’s quite likely that there will be a single victorious player, who managed to claim the largest territory by outwitting everyone else.
A small example to illustrate how the capturing rules affect the strategy: Assume that once the board is almost filled up, one player clearly has the most points. They have one big group which has 4 solid eyes, and no external liberties. It may look hopeless for the other players! However, if they manage to all work together (coordinating in the public thread or in a series of 1-on-1 threads, since a 4-way private thread is not allowed), they can still potentially capture that group by playing in all 4 eyes at the same time.
Thus, until you have 5 eyes you’re not completely alive! However, during the game some players may be eliminated (by losing all of their stones on the board), which may decrease this number and make it easier to live.
This became a bit more rambly and a bit less condensed than I intended… hopefully it gives some idea of what the game will look like. But right now we are all very unsure of what’s going to happen, since it’s the first game of its kind!
