Animated Mystery Box Reveal Game for Live Stream (HTML/JS/CSS)

I am looking for a developer to build a standalone animated “mystery box” reveal game that will be used on Facebook Live.

This is NOT a customer-facing website. No payments, logins, or user accounts are required. The tool will be used by me only and shown live by filming my laptop screen with a phone during Facebook Live.

The game should display 100 mystery boxes on screen. Each box contains a pre-defined prize that I will supply via a CSV or JSON file.

During a live, when a winner finds a mystery box, I will click the relevant box number and:
- The box animates (shake / unwrap / open)
- The prize is revealed with a fun, high-quality animation
- The box becomes locked and cannot be opened again

The visual style must be bold, exciting, and easy to read when filmed on a phone camera. Animations should be smooth and dramatic (casino / instant win / mystery box style), not basic pop-ups.

Technical requirements:
- HTML / CSS / JavaScript
- Suitable for use in a normal web browser
- No backend complexity required beyond loading the prize data
- I must receive and own the full source code

Nice to have:
- Sound effect on reveal
- Confetti or glow animation
- Simple reset option for new competitions

Please include examples of interactive or animated web projects and your estimated cost and delivery time.
