- The Titanic demo asks players to order six dated event cards; their initials spell a word.
Field notes
The sample puzzle presents dated Titanic events as cards labeled [FACT], including the Southampton departure and the Carpathia's arrival in New York. The site says its case materials distinguish FACT, TESTIMONY, RUMOUR, and GAME. The homepage lists two available series, while the other historical subjects shown are marked coming soon.
