Field notes
The rules menu lays out three phases: edges wrap with poles closed, poles open after a promotion, or poles open after castling. A threat-view legend distinguishes attacks by color, including attacks that cross an edge or pole. The page also says the local rating is stored on the device and remains provisional for the first 10 games; changing level or using hints makes a game casual.
