Crack the case on every suspect number. Spot primes, unmask composites, match factor pairs, and track down common factors — before your clues run out!
Pick your grade level:
Tap PRIME, COMPOSITE, or NEITHER for each suspect (or press 1–3). Answer YES/NO factor checks, choose the correct factor pair, and round up every prime (or composite) in a timed lineup before the clock runs out. Remember: 1 is neither prime nor composite, and 2 is the only even prime. Chain correct answers into a streak to earn bonus clues and close each case fast! 🕵️
