Multi-Question Challenge Plugin

Overview

This plugin extends CTFd to support a new challenge type called "Multi-Question Challenge". It allows a single challenge to contain multiple sub-questions, each with its own question text, flag, and point value. The total score for the challenge is automatically calculated as the sum of all its sub-questions.

This is ideal for scenarios where a single task or artifact (e.g., a file to analyze, a service to exploit) has multiple flags to be found.

Features

• Create challenges with multiple, distinct sub-questions.
• Each sub-question has its own unique text, flag, and point value.
• A real-time progress tracking UI is displayed in the challenge modal, showing:
  • Total score acquired vs. total possible score.
  • Number of questions solved vs. total questions.
  • Number of questions remaining.
• The main challenge's score is automatically calculated and updated based on the sum of its sub-questions.
• Admins can set the challenge state to "Visible" or "Hidden" during creation.

2. Go to the "Challenges" page and click the "Create" button.
