The One Rule

Field notes

The interface separates a daily run, escalating play, training, and ranked matches, then adds room-based multiplayer with four-character join codes and invitation links. Multiplayer settings include speed, lives, rotation, and team configuration; the available formats cover everyone-against-everyone and duos with a shared pool of lives. A privacy notice says scores and return days use a random identifier, while account-related controls also appear in the visible interface.
