Purple Circle

Project brief

Theatres keep audiences coming back with gamified circles, quests and loyalty, not just one-off ticket sales, and the countdown teasers write themselves.

Expo / React Native app, Next.js + Mantine admin with an @xyflow quest-chain builder, and a Go (gqlgen) GraphQL backend on PostgreSQL with a River job queue, JWT auth and an OpenAI-compatible LLM call behind a graceful fallback.

Scope

Purple Circle is an audience-engagement platform for Austrian theatres (Graz, Salzburg, Vienna). Members join a theatre’s “Circle”, complete gamified quests (scan QR, attend events), earn badges and collect loyalty stamps. It pairs a React Native mobile app with a Next.js admin console (analytics, a visual quest-chain builder, badges and members) over one Go GraphQL API.

Outcome

Theatres turn ticket buyers into a returning community through gamified circles, quests and loyalty, with member analytics in one console.

Hard part

A node-based visual quest-chain builder, scheduled/relative unlock triggers, and one GraphQL contract serving both a React Native app and a Next admin. Progressive-reveal quests write their own teaser: the backend asks an OpenAI-compatible model for a 3 to 8 word phrase from the event context and auto-publishes on success, falling back to a draft the theatre edits when generation is unavailable.
