Arithmetic with AdMob and Leaderboard is an engaging LibGDX-based math game developed in Java using Android Studio. Designed to sharpen mental calculation skills, this fast-paced game challenges players to solve arithmetic problems within a 60-second time limit. Correct answers reward players with 10 points, while incorrect responses deduct 10 points, creating a dynamic scoring system that encourages both speed and accuracy.
Core Gameplay Mechanics
The game presents players with randomly generated arithmetic problems covering all four basic operations:
- Addition: Simple sums to complex multi-digit problems
- Subtraction: From basic to borrowing calculations
- Multiplication: Times tables and beyond
- Division: Including problems with remainders
The adaptive difficulty system ensures players are consistently challenged, with problem complexity scaling based on performance. The ticking clock adds excitement, pushing players to think quickly while maintaining precision.
