The manual entry is your escape hatch. Anything the app doesn't model natively yet, or any correction you want to make on the fly, can go in here with an optional note.
Good things to use it for
- Corrections — someone scored a city for 8 when it should have been 10? Enter +2 with a note like "city fix".
- House rules — special scoring your group plays with.
- Expansion features we don't yet model in the live forms, like trade goods majorities at end-game, big-meeple bonuses, and so on. The expansion pages tell you exactly what to enter.
Notes are worth writing
The log keeps every entry with its note, so a future you (or a confused friend) can scroll back and see why +5 showed up. A short tag — "pig field", "cathedral bonus" — is plenty.
