Primes GO

隨著素數去，你可以去外面尋找黃金區域。

The goal is to find as many prime zones as possible. They are located all over the world and have special coordinates. If you find a prime zone which you haven't discovered before, your prime score will be incremented. As you move your movement score grows. The greater the better - but don't forget: The prime score is much more valuable.
