About
A falling-block puzzle made of Japan's 47 prefectures: pieces clear when real neighbors touch.
The map of Japan has come apart. The land-pulling god lets the prefectures down into a box one by one. When two prefectures that really border each other touch, they join up and go back home (they disappear). Don't let the box overflow.
HOW TO PLAY
- Drag to aim, lift your finger to drop
- Tap the left or right side to turn the piece
- Neighbors that touch clear and score
- When a piece that falls after a clear touches another neighbor, that's a chain: a 2-chain scores double, a 3-chain triple
FEATURES
- Every piece is based on the real shape of a prefecture (simplified for play)
- Learn which prefectures border each other as you play
- A map of Japan built from the pieces: check any prefecture and its neighbors
- A short tutorial for your first game
- Hokkaido and Aomori, and Okinawa and Kagoshima, also count as neighbors
