An Android-based decentralized wireless engine enabling seamless App-to-App and App-to-Web local multiplayer card games without external servers.
Harness the power of local discovery protocols (mDNS/NSD, Wi-Fi Direct, and Bluetooth Low Energy) to automatically bridge nearby Android devices. Players can instantly join lobbies, deal cards, and sync game states with sub-millisecond local latency, entirely isolated from the wider internet.
Break the platform barrier. The Android application can dynamically spin up a lightweight WebSocket/HTTP server on the local network. Anyone on the same Wi-Fi can simply scan a QR code or enter a local IP address into their Web Browser to instantly join the table—no installation required.
Relying on a master-client architecture locally means if the host disconnects, the game dies. Our engine utilizes a distributed mesh topology where the deck and player hands are cryptographically signed and shared among peers. This allows seamless host migration without exposing hidden cards if the original lobby creator drops out.
Card games require absolute trust. The engine employs cryptographic hashing to ensure that no client can peek at undealt cards or manipulate their hand. Every draw, shuffle, and play is verified by the local mesh consensus before rendering on screen.
