- Curious data players and people learning Diplomacy
- Worth noticing
- Trendle serves five new charts daily, with the same set for every player.
Field notes
Trendle's daily charts are shared across players, and its streak mechanic rewards drawing close to the real data line. The other game teaches Diplomacy through a guided campaign as Turkey, moving from rules to tactics. The homepage also says the project sets no cookies and loads nothing from other sites; each game has its own privacy notes, terms, and data sources.
