Earned by speaking
Every mission goal you complete adds its YAP. A failed goal adds nothing, and you can always replay a mission.
YAP and Zones
Speak, earn YAP, open the next zone.
YAP is what TUD gives you for speaking. You spend it to open the next CEFR zone of a city, one zone at a time, and to collect buildings in the shop.
Earning YAP
One currency, earned one way.
Never sold for money
YAP cannot be bought, and nothing in TUD is random. What you hold is what you earned.
Kept in TULLET
TULLET is your YAP wallet in the app: your balance, what the next zone costs, and every zone you have opened.
Zones
Every city has its own climb.
Each city map has six CEFR zones, from A1 to C2. A1 is open from the start. When you hold enough YAP for the next zone, the level pill in the app shows it, and one tap opens it. You can sell the newest zone back for a quarter of what you paid: it locks again, and the missions you finished and the buildings you bought there stay yours.

The shop
Collect the city, building by building.
Buildings for YAP
Every mission place is a building you collect by playing its missions. A building you have not earned yet can be bought in the shop, in a zone you have opened.
Spending never closes a zone
What you spend in the shop comes off your balance and never closes a zone you opened. A zone locks again only if you sell it back.
Sell back what you bought
The shop buys back only what it sold, for a quarter of the price you paid. Buildings you earned by playing stay yours.
TUD Pro
Free all the way to C2.
TUD Pro plays every zone early without opening it. Free learners reach C2 with YAP alone: Pro is never required.
