Our research into player purchases has shown that you tend to purchase for the extras, not because your trial ran out. So, we're allowing trial players all the time they need to decide to purchase, and meting out the non-essentials in tasting portions. The plan also has the interesting side-effect of letting paying players know exactly when their favorite inn games will be overrun by Greenies, and giving them the rest of the week to play with the regulars.

With the new release (by 10/21), we'll be extending the time of the free trial indefinitely, but limiting trial players' off-ship puzzling. The duty puzzles and regular dueling are always available to trial players. The remaining puzzles each are available for free one day of the week. So, a trial player could be playing "Treasure Drop Tuesday," but can't play Treasure Drop on Saturday, instead playing "Shipwright Saturday," or some such. On a Subscription ocean, subscribing opens up the whole game as always. On Doubloon oceans, the Labor Badge will open all labor puzzles, and the new Parlor Badge will open all parlor games.
The one special case is Swordfighting. A trial player can always have street challenges and boarding battles, but treats like Swordfighting tourneys and brawls work on the once-a-week basis as above. So, Swordfighting will have a free Tourneys and Brawls day, but on other days, those options are reserved to Subscribers or Parlor Badge owners.
