About Keep Prime Numbers

Keep Prime Numbers asks you to clear a path for composite numbers while protecting primes. You remove blocks by clicking or tapping them, causing numbered blocks to drop through gaps you create. The goal is to let every composite number fall off the screen without losing a single prime. Each level presents a new tower of numbered blocks where careful planning matters – you must study the stack, identify which numbers are prime and which are composite, then remove blocks in the correct sequence. One wrong tap sends a prime tumbling out, ending your run. The puzzle grows trickier as levels introduce more blocks and tighter formations, forcing you to think several moves ahead. Poki Games hosts this brain-teasing challenge that blends number theory with spatial reasoning, rewarding players who can spot primes quickly and execute a flawless demolition plan.
