One shared screen.Everyone has a role.
01 / Challenge
Start playing without installing an app.
Players need to join a shared session quickly from their phones. The shared screen shows game progress, while personal interfaces handle each player's answers, actions and information.
A single platform supports different mechanics: short answers and voting, bluffing, negotiation and collaborative storytelling.
02 / How it works
One room.
Different perspectives.
- 01 / HostCreate a room
The host selects a game and opens the shared screen in a browser.
- 02 / JoinConnect phones
Players join with a code or QR, without registration or installation.
- 03 / PlayPlay together
Answers and votes arrive from smartphones; stages and results appear on the shared screen.
03 / Technical delivery
The server runs the game. Clients handle actions.
Node.js and Socket.IO connect the shared screen with smartphones. The server maintains room state, controls stages and timers, processes actions and sends updates to players.
Role-based data separation keeps personal information off the shared screen. Reconnection restores a player's access to the current session.
Responsive shared-screen and phone interfaces use HTML, CSS and JavaScript.
04 / Outcome
A live product you can try.
An original product, not a client commission. The project is live and continues to evolve. This case presents its mechanics and technical implementation, without claiming audience or commercial performance figures.
