Keep Prime Numbers

About Keep Prime Numbers

Keep Prime Numbers is a clever puzzle game that tests your understanding of prime numbers. In each level, you are presented with a set of numbered balls resting on supports. Your job is to identify which numbers are prime and which are not, then remove supports accordingly.

The core challenge is to protect the balls with prime numbers while eliminating all composite-numbered balls. You must carefully choose which supports to remove, as the physics can cause chain reactions. If a prime-numbered ball falls off the platform, you fail the level and must restart.

The game gradually increases in difficulty, introducing more balls and trickier arrangements. It is a great way to sharpen your mental math skills while enjoying a strategic puzzle experience. Suitable for all ages, Keep Prime Numbers makes learning about primes fun and engaging.

With its simple mechanics and increasing complexity, the game offers a satisfying blend of math practice and problem-solving. Can you keep all the primes safe while clearing the rest?

How to Play Keep Prime Numbers

At the start of each level, examine the numbered balls on the platform. Identify which numbers are prime. Your goal is to remove the supports under non-prime balls so they fall away, while ensuring that prime-numbered balls remain on the platform. If a prime ball falls, the level is lost. Progress through levels by successfully eliminating all non-primes without losing any primes.

Tips for Keep Prime Numbers

Remember that prime numbers are only divisible by 1 and themselves. Common primes include 2, 3, 5, 7, 11, and 13. Before removing any support, think about how the balls might shift. Sometimes removing a support under a non-prime ball can cause a prime ball to roll off. Plan your moves in advance and try to clear non-primes in an order that minimizes risk to the prime balls.
