FACTOR BUSTER

Features
Read full description

Break every number down into primes. Beat two bosses to clear — before time runs out. FACTOR BUSTER is a prime factorization time attack. A number appears in the middle of the screen. Tap the prime buttons below to divide it. Each correct prime fires a beam; break the number down to 1 and it shatters in an explosion, and the next number flies in. HOW TO PLAY - Tap a prime that divides the current number - A wrong prime costs 3 seconds - The faster you solve, the more you score (bonus for no misses) - The 5th number of each stage is a boss. Beat the stage 2 boss to clear FIVE DIFFICULTIES Easy, Normal, Hard, Extreme and God. Higher difficulties add bigger primes and take away 2, 3 and 5 — in God mode you fight with primes from 59 to 97 only. TWO MODES - Beginner: tap a dividing prime to attack at once - Expert: tap primes to charge, then FIRE. The product stays hidden, so multiply in your head FEATURES - Random numbers every run, balanced by the number of primes and digits - Music and backgrounds for each difficulty, ten bosses - Touch controls that work with two thumbs - Japanese and English - No account. Just one short ad after every 5th game over (remove it with the one-time Remove Ads purchase) - Records are stored only on your device
