Regardless of how your team does, everybody plays two playoff games. Your team paid for 9 games, so you get 7 season and 2 playoffs (8 season if you are in a division with double headers).
Even if you lose in semis, you still get a game the next week!
The playoff schedules are all released at least 72 hours in advance of your game. If your team is in playoffs, you can click on the event and see your attendance, since games towards the championship do not allow spares and require every player to have attended 3 games minimum to participate.
Right now, we are dealing with some backend issues so Premier and Thursdays have not had their attendance added to the events. That will happen in the next couple days, with Premier no later than Sunday and Thursdays no later than Monday.
