Mobile Game App Development - Mega Millions Style

I am looking to develop a mobile game app similar to the Mega Millions concept. The app will allow users to register and create accounts under "Djangui Come aux State." Users can purchase tokens to load their wallets, with each token costing 10,000 FCFA. Players will use one token to participate in the weekly Djangui game, where the winner is selected by the admin every Sunday at 8 PM Paris time.

The winnings will be credited back to the player's account or another designated account. A new game will open every Sunday at midnight and close before the next drawing. The total amount collected will only be visible to the admin, while 50% of this amount (the winning prize) will be displayed incrementally and visible to players as it grows.

This app is targeted exclusively at French-speaking countries such as Cameroon, Gabon, Congo, and others.

Key features include:
- User registration and account creation
- Token purchase and wallet integration
- Weekly game participation system
- Admin-controlled winner selection
- Prize distribution system (50% of total amount collected)
- Incremental display of winning prize for players
- Multi-language support (French-focused)

Ideal Skills and Experience:
- Experience in mobile game development (iOS and Android)
- Knowledge of secure payment gateway integration
- Proficiency in creating user-friendly interfaces for French-speaking audiences
- Strong backend development skills for admin controls
