How chapter progression works
Cities, themes, unlock rules, steps, stamps, and streaks — explained without opening the app.
The chapter map is WooMoa's curriculum spine. Cities group related themes; each theme is a focused lesson with steps — not a single quiz. Progress is measured per theme and with stamps when you master a unit.
Unlocking cities and themes
The API returns unlock text for locked cities and themes so you know exactly what to complete next. Early cities are usually available immediately; later content opens as you finish themes in earlier chapters.
This design prevents skipping to advanced vocabulary before foundations are practiced and gives the map a game-like sense of travel between cities.
Steps and correct answers
Each topic divides play into a fixed number of steps (shown on the card). Within a step, you must reach a target of correct answers before the step completes. Wrong answers may remove partial progress according to topic rules.
You will see step progress in the play header while you are inside a topic session.
Stamps and completion
When all steps in a topic are done, you may earn a stamp on the map — a visible mark that you finished the unit. Stamps are motivational markers; they also signal to you which themes are ready for occasional review.
Returning to a completed topic for review is still valuable; adaptive scoring can surface weaker items again.
Streaks and daily goals
When retention is enabled on the server, the chapter map shows your streak and daily goal progress. Qualifying play days extend your streak; completing a daily answer goal can grant bonus coins or hints after a correct answer.
These features are optional server settings — if they are off, the map still tracks theme steps and stamps as before.
Adaptive difficulty inside a theme
WooMoa chooses the next question from the content pool based on your recent performance in that locale pair and topic. That means two players on the same topic may see different sequences.
All answers are checked server-side. Client-side tricks cannot fake progress — which keeps leaderboards and personal records meaningful if you link an account.
