Arithmetic with AdMob and Leaderboard is a fast-paced math training game built using LibGDX and Java in Android Studio. This brain-training app challenges players to solve arithmetic problems within a 60-second time limit, rewarding correct answers with +10 points and deducting 10 points for incorrect responses. The game combines educational value with competitive elements through Google Play integration and monetization features.
Core Gameplay Mechanics
The game presents players with a series of arithmetic problems including addition, subtraction, multiplication, and division. Each session lasts exactly one minute, creating an intense mental workout that improves with regular play. The scoring system encourages accuracy over speed, though quick thinking does provide an advantage.
- Dynamic difficulty: Problems automatically adjust based on player performance
- Visual feedback: Immediate scoring updates after each answer
- Time pressure: The ticking clock adds excitement to math practice
- Progress tracking: Players can monitor their improvement over time
