The Primes game will make you remember simple mathematical rules, since the elements of the game will be red and blue balls. The blue balls have prime numbers on them, and the red balls have the rest. Prime numbers are those that can be divided without remainder by one and by themselves. The balls will fall from above, and below there is a bowl of balls. When you click on it, you change the color of the balls. Watch the falling object and change the color if it does not match the falling ball. Collect points and don't make mistakes in Primes.
