HOW TO PLAY
- Invaders carry math problems. Solve one, type the answer, press ENTER — your ship auto-targets and blasts the matching invader.
- Chain correct answers to build a combo multiplier — up to ×5 points. One wrong shot resets it.
- Answer fast (under 4 seconds) for a speed bonus.
- Don't let invaders reach the shield. Five breaches and the mission fails.
- Grab power-ups: time freeze, double points, shield repair, and the mighty NOVA bomb.
- Every 5th wave is a BOSS. Answer its questions to break its armor — answer during its attack charge to interrupt it!
- After the mission, your Report Card shows accuracy, streaks, and exactly which facts to practice.
