That's easy to explain, read the details for the server:
Tournament
This is a tourney server. Countries on this server are split up into several different games: game A, B, and C. Game A is the upper level of tournament. Only the top 50% of players in game A stay in game A after the reset is complete. The bottom 50% are randomly assigned to the lower level games, B and C. Similarly, the top 25% of players in games B and C move up to game A at the end of the round. New countries will be assigned to the lower level games. All games share the same public market.
