WEB BASED EDUCATIONAL GAME SAME AS https://quizizz.com

Hi,

I urgently require a web-based educational live and assigned games / quiz management system, similar in concept and functionality to Quizizz.

The platform must allow students to participate in interactive quiz games through a live link and/or unique game code, without requiring students to create user accounts. The system should support unlimited or high-volume participants joining the same game session through a shared link/code.

There must be a secure admin panel where we can create, edit, duplicate, publish, and manage games/quizzes. The admin should be able to create different question types, including:

Multiple-choice questions
Written answer questions
True/false questions
Image-based questions
Audio/sound-based questions
Timed questions
Points-based questions
Questions with explanations after answers

The system should allow us to add pictures, audio files, sounds, and other media to questions and answers where required.

The platform should include both live game mode and assigned/self-paced mode, so students can either play in real time during a class or complete the game independently within a set time period.

Required features include:

Live leaderboard
Real-time score updates
Student nickname entry before joining and selection of Avatars
Unique game code and join link
Teacher/admin dashboard
Question bank
Ability to create categories, levels, subjects, and classes
Timer settings for each question
Automatic marking
Manual review option for written answers
Game reports and analytics
Student performance data
Export results to Excel/CSV/PDF
Ability to reuse and edit previous quizzes
Mobile, tablet, and desktop responsive design
Clean, modern, child-friendly interface
Secure login for admins/teachers
Option to show questions on a main screen/projector
Option for students to see questions on their own devices
Ability to add branding, logo, colours, and custom domain

The live gameplay should be smooth, fast, and engaging, with instant feedback, score animations, rankings, and a professional user experience similar to Quizizz, but built fully for our own organisation with our own tailor-made dynamic questions, answers, subjects, and branding.

The system should be built on our own website/platform and must be scalable, secure, and easy to manage by non-technical staff.

Please provide:

The best quote, fastest delivery, strong experience, and good working samples will be prioritised.
