-- Primes! --

Primes! is a game of speed, reaction, and knowledge. The center square will have a prime number in it and the eight surrounding squares will have other numbers. One of the eight will be the next prime number after the one in the center. Click the correct number and you will advance to the next level.

Every level the center tile will have a random prime number, so be ready!

Each level is 10 seconds and if you do not advance in the allocated time, you lose.

Gain 10 points (times the amount of seconds remaining) for every correct guess, and lose 5 points for every wrong guess.
