Dark Prince: Welcome! Good to see you here :) For League play you don't have to be a member. The only tghing is that BrainKing requires you to have a paid membership to participate in more than one tournament at the same time. The tournament you are in has to finish completely (even when you don't have any games left because you're out) before you are allowed to enter a new tournament.

Chaos:
I have found the tournament information here a bit confusing.
Do I join the league or simply enter the tournament?
Where do I find the Espionage tournament,
how do I enter and when?

Dark Prince: You simply enter the tournament. On BK people create their own tournaments, rather than them being created by the site. On the tournaments link, what you see are a list of open tournaments, the tournament name and who created the tournament. Most tournaments (like IYT) have multiple games types and you choose the ones you wish to play in. Not all tournaments have all game types and some are dedicated to one game type only. NB. with a pawn membership you may only enter 1 tourny.See posts below.

The League will occasionally create a specific espionage tourny and all are invited to play. The link shows a tourny already under way.

You can also find games under waiting games. You can reduce the list by applying filters to this so so you can't see the Ludo game for example. Or choose new game and it will go into the waiting room.

There are also team touraments, which you play as part of a fellowship. Here is a link to one under way:

Chaos: You can ask Fencer to remove you from tournament, where you finished all your games and you cant advance or win tournament.

Dark Prince: Indeed, I think the tournaments here are organised in a very confusing way. We anounce the League Espionage (=sabotage) tournaments here with a link so you can go straight to the tournament. You can make this discussionboard favourite (see on top of the board). That way you'll always see on your main page when there's a new message.

The first League tournament is still running the first round is on it's end. You can follow it's progress here:
