Killer Party

A premium party game you play in a room: the group gathers around one shared TV (host screen), each player uses their own phone (their private view), and the game stays perfectly in sync while keeping every player's secret role hidden.

• 01A phone-per-player + shared-TV-host (second-screen) architecture.
• 02A deterministic game-state engine so every phone and the TV stay in sync and the game resolves the same way every time.
• 03Private per-player role dossiers — each player only ever sees their own identity and information.
• 04The full play flow: evidence reveals, pressure prompts, and the accusation → killer-reveal sequence.
• 05An admin console to run the game and a working storefront that sells the game packs.

Party games that run on a group's phones usually fall apart in practice — screens drift out of sync, secret roles leak, and someone ends up refereeing instead of playing. The goal: a premium murder-mystery night that stays perfectly in sync across one TV and eight phones while keeping every player's secrets private — built entirely by one person.

Real-time multiplayer with shared and private state is genuinely hard — sync, secret information, and deterministic resolution across nine devices at once — and it's built solo across the entire stack, including a commerce storefront and a tested codebase. It's the proof I'm not just Shopify: I build real product.
