Published Mobile Game (React Native, Expo)
Google Play: https://play.google.com/store/apps/details?id=com.anonymous.Numbero10
Numbero is a simple but polished logic game inspired by Bulls & Cows. Players guess numbers against an AI with points, energy, and rankings, designed for fast and engaging gameplay with clear rules and statistics.
Numbero focuses on clean gameplay, simple animations, and meaningful progression. Key design principles:
- Easy-to-understand mechanics with neobrutalism-inspired UI
- Offline-capable single-player AI mode
- Energy system: 1 game = 1 energy, refill via reward ads or coins
- Coins earned based on performance: attempts, time, number length, and AI victory bonus
- Ranking points synced with Google Play Games Services
- In-game guide and tutorial explaining rules, strategy, and keyboard mechanics
Planned enhancements include multiplayer rounds, puzzle/campaign mode, hints, and improved tutorial.
