KAMAYUU

Players can practice solo or create private multiplayer tables. The interface includes onboarding, player identity, tutorials, settings, score tracking, and table interactions, with card art, sound, and haptic feedback. Online play requires the configured backend.

The problem

KAMAYUU centers on remembering cards and tracking what other players know. The game needs to make hidden information, turn order, and reactions understandable while supporting both solo and online play.

The product response

The project includes a dedicated rules engine, guided tutorial, card interface, and solo AI opponents. Online play uses Supabase authentication, realtime room communication, and a deployed game Edge Function.

KAMAYUU makes memory part of the strategy: players track cards, follow changing table knowledge, and decide when to react.

Solo practice works independently, while private online tables connect players through a server-backed multiplayer flow.

Scope and technology

KAMAYUU is a browser-based card game built around memory, tracking, and timing. Players can practice solo against AI opponents or use private online tables to play with friends. The app includes onboarding, a tutorial, player profiles, and a score ledger. Its online multiplayer uses Supabase services; solo play runs in the browser.
