About
Put the names back on the map, one region at a time.
Taiwan: 22 counties and cities, 368 townships and districts.
Japan: 47 prefectures, 1,902 municipalities.
South Korea: 17 provinces and metropolitan cities.
United States: 50 states + Washington, D.C.
Everything is bundled in the app: no network, no sign-up.
TWO WAYS TO PLAY
- Fill the Map: the board starts blank. Pick a name from the list for each
region, submit, and watch the answers flip over one by one as the camera
moves across the map. Wrong answers show the correct name.
- Tap the Map: the app names a place, you tap where it is.
TWO BOARDS, SWITCH ANY TIME
- Satellite: Apple Maps imagery with real coastlines and terrain.
- Vector: clean colour blocks with crisp borders.
TAIWAN: 31 STAGES IN 9 CHAPTERS
From a single city (Keelung, 7 districts) up to all 22 counties, the
41-district Taipei-New Taipei board, and a timed 48-district finale.
7 boss stages are against the clock.
Japan, South Korea and the United States each have stages per region and
one for the whole country.
SCORING AND STARS
100 points per region, combo bonus for streaks, and leftover seconds count
in timed stages. Stars depend on accuracy only: 20% for one star, 60% for
two, all correct for three. Your best result is saved per stage.
PLACE-NAME LANGUAGE
Korean and US place names can be shown in Traditional Chinese, Simplified
Chinese, Japanese, Korean or the local name (Settings > Display language).
PROGRESS MAP
The home screen map lights up as you clear stages.
LANGUAGE NOTE
The interface is in Traditional Chinese. Place names for Taiwan and Japan
are shown in Chinese characters.

September 21, 2026
- Interface and place names now in English, Japanese, Korean, Traditional and Simplified Chinese; follows your device language, or pick one in Settings - English, Japanese, Korean and Simplified Chinese names for every region in Taiwan and Japan - Much smoother reveal on the satellite board, especially for the United States and South Korea - Shorter English labels on the board (Beitou District -> Beitou) so they no longer overlap
