The game Keep Prime Numbers invites you to get acquainted with prime numbers and save them from their proximity to complex numerical values. First you need to remember what a prime number is. The rule in mathematics is that a number is prime and can only be divided by itself. For example, you can only divide the number 11 by 11 to get zero, but you can also divide the number 12 by 3 or four. In each level, you must get rid of the complex number inside the ball by removing the support from under it, while the ball with the prime number must remain on the platform in Keep Prime Numbers.
