Bag Sort: Puzzle Game Development
Bag Sort: Airport Puzzle is a Flutter mobile game built for Android, featuring luggage sorting gameplay in a cartoon airport style.
The core challenge
Design a mobile sorting game that remains simple to understand while becoming progressively faster and more difficult.
Key Requirements
- •Sorting mechanics using drag-and-drop and tap gestures.
- •Multiple progression tracks including levels, scores, missions, and achievements.
- •Retention mechanics like daily rewards, endless mode, and monetization via rewarded ads.
Architectural Breakdown
- ✓Client Engine: Flutter mobile app rendering cartoon graphics and bag variations.
- ✓Monetization: Google Mobile Ads SDK integration for rewarded ads.
- ✓Release Pipeline: Google Play Console testing track configurations.
Implementation Strategy
We built the game in Flutter, utilizing reactive state structures to track lives, combos, levels, achievements, and active scores.
Technical Decisions
- •Chose Flutter to achieve rapid layout iterations and leverage Dart UI rendering speed.
- •Implemented a local state system to coordinate achievements and progression paths.
Key Challenges Solved
- •Tuning drag-and-drop responsiveness under progressive difficulty was solved by refining hit-box tolerances on luggage design variations.
Quality Assurance & Testing
Ran Google Play internal testing campaigns to collect feedback on controls, difficulty progression, and ad integrations.
Project Outcome
A production-focused Android puzzle game with multiple progression and retention systems.
