About This Game
Every falling monster wears a number — and every number is secretly a product of 2, 3, 5, and 7. Math Factor Shooter turns prime factorization into arcade defense: fire a factor and, if it divides the bottom-most monster's number cleanly, the value shrinks — and so does the creature — until it collapses to 1 and bursts into points.
Bigger starting numbers pay out more when they pop, while shots that don't divide bounce off and cost you points, so wild guessing is a losing strategy.
The pressure climbs along a real difficulty curve: early stages serve numbers built from just two prime factors, but later ones stack three, four, then five factors deep, spawns arrive faster, monsters descend quicker, and up to five of them crowd the sky at once. Let a single one cross the red line and the run ends instantly.
It's mental-math training brilliantly disguised as a monster shooter — ideal for students sharpening arithmetic and grown-up number nerds chasing flow.
Game Tips
- 💯 Monsters that start with bigger numbers pay more when they fall
- 🔍 Even numbers take a 2; ending in 0 or 5 means 5 for sure
- 🚫 Firing a factor that doesn't divide costs points — think first!
