Interactive games for corporate events: one big screen and your guests' phones

The setup has two parts. The big screen, whether a TV, a laptop on a projector or an LED wall, opens the game in a browser. It creates a room and shows a QR code. Guests scan it, and a controller opens in the phone browser: four answer buttons in a quiz, a joystick in a race or a shooter. Nobody installs an app, and guests do not need an account to play.

Everything that matters happens on the shared screen. Phones only send what players press; the game server applies those actions and the screen shows the result to the whole room. That is why the format works at events: people look up at the same screen, react together and see the score change at the same moment.

Compared with a paper quiz, there are no answer sheets to hand out and no scores to add up: the server counts the points, and the results appear on the screen as soon as the match ends. Compared with a show of hands, everyone answers at the same time and every answer counts.

What you need:

• One screen everyone can see, with a browser and internet.
• Guests' own phones. They need internet but not your Wi‑Fi: mobile data works.
• A host who starts the room, chooses the settings and keeps the pace.

A guest whose camera does not read the QR code joins with the short room code from the lobby page. The step-by-step setup is on the How it works page.

A week before

• Choose the format and the game (see the examples below).
• For a quiz with your own questions, write them in the Quiz Pack Builder: 5–60 questions, four answers each, one of them correct.
• Count how many people will play at once and plan rooms: up to 8 players in a free room, 16 or 30 in supporter rooms, within each game's own limit.

On the day, before guests arrive

• Open the game on the actual screen at the venue, start a test room and join it from two phones: one on the venue Wi‑Fi and one on mobile data.
• Check that the QR code can be scanned from where guests will stand.
• Set up the match before it starts: number of rounds, time, language, question pack or difficulty.

During the game

• Explain it in one sentence: scan the code, your phone is the controller.
• Start with a short warm-up round so everyone sees how it works.
• Keep the rounds short and announce the winners out loud.

After the game

• The screen shows the results and a "play again" button for a rematch. The share card with a QR code lets guests take the moment with them.

Corporate party: an event quiz with phones. Quiz Battle takes 2–30 players. Questions about the company's year, new colleagues and office legends work better than general knowledge: people laugh at the answers, not only at the score.

Conference: a quiz between talks. Five to ten questions on the topic of the next talk warm up the hall, and the same questions after it show what stuck. One language per pack, so a bilingual conference gets two packs.

Team day: co-op games. In Immune Z (a co-op zombie shooter for 1–10 players) and Tower Defence (co-op defence for 1–4) the team wins or loses together. In WarLine, teams fight for territory, 2–20 players: departments against each other, with the score in front of everyone.

Brand stand or activation: short rounds. Race Track takes 1–8 players and fits a stand where visitors come and go. A leaderboard for the whole day on the big screen and your logo and colours are custom work.

Training and onboarding: a knowledge check. A pack built from the training material turns revision into a match. Results appear on the screen right after the last question.

Online event or stream. WarLine has a streamer mode: Twitch chat viewers send commands to the game. The chat is read without API keys.

A party at home or a birthday. A free room holds up to 8 players, enough for a living room with a TV.

• Room size. A free room holds up to 8 players, supporter rooms 16 or 30, and every game has its own limit: Tower Defence 4, Race Track 8, Immune Z 10, WarLine 20, Quiz Battle 30. A larger audience needs several rooms in parallel or a custom build. We size it together; I do not promise a headcount without seeing the event.
• Internet on both sides. The screen and every phone need internet. Mobile data works, but a hall with no signal needs guest Wi‑Fi. Test it on site.
• Visibility. A laptop screen works for a table of eight, not for a hall. The screen has to be readable from every seat.
• Not everyone plays. Some guests prefer to watch. The shared screen keeps them in the moment anyway, so there is no need to push.
• Your own questions require the Patron level on Patreon (see the support page). Branding of the screen is custom work, not a setting.
• Phones. A guest without a smartphone can team up with a colleague and play from one phone.

• One screen and guests' phones are enough for the whole room to play together, with no app and no shared Wi‑Fi.
• Choose the format by the goal: a quiz for a large mixed group, co-op games for a team, short rounds for a stand.
• Test the screen and the internet at the venue and plan rooms by the number of players.
• Write your own questions so the quiz is about your people.
