The cannon fires automatically — drag or use the ← → keys to aim. Pick a divisor gun (2, 3, 5, 7) as your ammo and blast each falling number down to 1 so it explodes. Don't let numbers reach the ground!
A number can only be hit if it's divisible by your selected gun!
Factor Blaster is an arcade math game for kids aged 8 and up that turns factoring into a fast, satisfying shooting gallery. Numbers like 90, 210, or 630 drift down from the top of the screen, and you defend the ground by blasting them apart. Pick one of four divisor guns — 2, 3, 5, or 7 — then tap a number to divide it: 210 hit by the 7 gun becomes 30, then the 5 gun makes it 6, and so on down a chain until it reaches 1 and explodes for bonus points. Every number is built so it can always be fully reduced, so there's never a dead end — just a puzzle of which divisor fits. Chaining correct hits builds a combo multiplier, while a wrong divisor costs points, so quick recognition of divisibility and prime factors is rewarded. It runs on any phone, tablet, or computer with no sign-up.
