System architecture

Each Smart Hex handles its own sensors and number display. The Base Board combines these observations into a physical board model. A hardware-independent game engine validates game commands. Web interfaces present the appropriate information to players.

This is a logical architecture. The Base Board owns coordination; the exact execution location and implementation language of the game engine and API are still open.

Component	Owns	Boundary
Playable Pieces	Passive identity and physical interaction	No software or game rules
Smart Hex	Local sensing, filtering, OLED rendering, communication	No game legality or global geometry
Base Board	Power distribution, enumeration, mapping, coordination, networking	Converts electronics into meaningful positions
Display Unit	Public web interface on a Raspberry Pi and screen	Must not receive private player data
Mobile Web App	Private player interaction on existing phones	Requests actions through the game API
