Who Wants to Be a Millionaire

A digital recreation of the classic TV game show. One contestant answers 15 questions of increasing difficulty worth up to £1,000,000. The host controls all game flow from a separate panel, while the audience can vote on answers from their phones.

How to Play

1. One contestant sits in the hot seat and answers 15 questions, worth up to £1,000,000.
2. Each question has four options — A, B, C, D. Only one is correct.
3. The contestant tells the host their answer; the host selects it on the Host Panel.
4. Safe havens at £1,000 (Q5) and £32,000 (Q10) — getting a question wrong below these amounts wins nothing; above them the contestant keeps the floor amount.
5. The contestant can walk away at any time and keep the prize they've already won.
6. Three lifelines, each usable once:
   • 50:50 — removes two wrong answers, leaving one correct and one wrong
   • Phone a Friend — 30-second timer for the contestant to consult someone
   • Ask the Audience — audience members vote on their phones at /vote; results shown as a live bar chart

Pages

URL	File	Purpose
/	millionaire.html	Game display — contestant and audience screen
/host	millionaire-host.html	Host panel — controls all game flow
/vote	millionaire-vote.html	Audience voting — one per phone during Ask the Audience

Game Display (/)

The main player-facing screen shown on the TV or shared display. Shows the current question, answer options with visual states (selected → revealing → correct/wrong), the money ladder, and active lifeline results (audience chart, phone timer). Updates in real time from the host panel.

Host Panel (/host)

The host drives the entire game from this panel:

• Load questions, select the contestant's chosen answer
• Trigger lifelines — 50:50 removes answers on both the host and display; Ask the Audience opens voting and displays the chart when closed
• Mark answers correct or wrong
• Walk away / continue decisions
• Reset for a new game

Audience Vote (/vote)

Players open this on their phones during the Ask the Audience lifeline. Shows the current question and four answer buttons. Each person votes once; the host closes voting from the Host Panel which then reveals the results on the game display.
