From now on Hnefatafl supports tournaments. This version now supports Knockout (Single Elimination) tournaments for all supported variants (including custom variants). We will start with three tournaments (Copenhagen, Hist. Tablut and Fed. Tablut). New tournaments will be created every week or if otherwise deemed a good time. Each player can participate in those tournaments. Due to the type of tournament the participation number gets culled to 2^n once the tournament starts. This means tournaments support those player counts: 2, 4, 8, 16, 32, 64, 128, 256 and so on, doubling with each step. If for example 260 players joined, the last 4 players won't be able to participate. So join early to get a better chance for a fixed place. There is currently no fixed start date for any open tournament. We will start them once the registrations stagnate and the numbers pass an acceptable number of players (no one has the need for 2 player tournaments ;) ). During the tournament players will be playing against random opponents and the sides get chosen randomly. The winner of the match continues on to the next round. There is currently no timeout for the matches to make a global tournament possible. So this works on an honor system. So please try to move as fast as possible (without making rushed moves of course). If a players gets caught trying to stalemate a match by not moving this will be manually resolved. If for whatever reason you don't think you will be able to compete the match in a reasonable timeframe you can still surrender. New tournament types (double knockout, leagues etc.) may be added with future updates. Full changelog:

• Tournaments are now available. We will regularly create new tournaments for everyone to participate in.
• Opponents will be marked with an "activity indicator" during a match to show if they have been online during the recent minutes.

• Added a new achievement.
