Quizmaster is a Scala web application for conducting live quizzes over the internet. It provides distinct views for players to submit answers, a public quiz display for audiences, and a master control interface for scoring and controlling quiz flow.

Key Features

• Configure quizzes and many question types via a YAML configuration file
• Player-facing answer submission page and a public quiz display that shows questions and scores
• Master view with scoring controls, question navigation, timer controls and keyboard shortcuts
• Supports audio and video playback during questions and media controls from the master UI
• Lightweight deployment: runs on a JVM (Java 11) and packaged releases; Docker Compose presets available for containerized deployment
• Demo configuration included to illustrate most question options; optional masterSecret for controlling access to master UI

Use Cases

• Run pub-quiz or trivia nights with remote or in-room participants
• Classroom quizzes and formative assessments where instructors control pacing and scoring
• Audience interaction at events or conferences with a live display and player submissions

Limitations and Considerations

• Requires Java 11 (JDK 11) and a JVM; familiarity with deploying JVM applications is needed
• Quiz content is driven by YAML files; there is no built-in visual quiz editor
• No built-in persistent user account system by default and limited scalability guarantees for very large concurrent audiences without additional infrastructure

Quizmaster is a focused, configurable tool for live quizzes and audience participation. It is best suited for organizers who are comfortable editing YAML configuration and running a JVM/Docker-based service.
