If the game got the winner, it will be closed. After couple days or more, I will move it to the Closed Games section. You can still view those games, and gain some knowledge from the game, but you can not participate in the closed games anymore. All open games and recent closed games will be remained in this section. 

If the game has been sit there for a long time, and no activities are going on there, i will also close it. Long time means more than one month Have fun!
