The games from the Battleboats #7 - you have already played all the games from that tournament - and currently there is 1 game left in that section (both players looking for last boat) - and once that last game is done in the section, you are allowed to enter a new tournament.

If you do not want to wait for that last battleboat game to be complete, you can send a nice message to Fencer and ask him to allow you to enter your next tournament since you have finished all the games in the Battleboat #7 tournament.

Hope this helps!
