Numerus Primus

Find all 25 primes out of 100 within 2 minutes. By selecting the right sequence in a round, you can unlock 7 out of 14 Achievements. All Achievements will raise the bonus-multiplicator at 1%, who affects the calculating of the end-score. You can find a list of the Achievements in the menu of the client.

In every game you can use 5 tips, which selects one prime. This selection holds on until the number is touched. Using Tips affects your score. On the one hand your canniness-bonus disappears, on the other hand your tip-bonus decreases.

Finding prime-twins (primes with a difference of 2) is taking a positive effect. For one it raises the Twin-Bonus (TB - An extra-charge before applying the bonus multiplier), and second, every prime- twin allows you to select all remaining primes for 5 seconds. This happens by touching TB (certanly only if TB is greater than 0). Using TB kills the canniness-bonus for this round.

If your device is online, new scores will be uploaded to the server automatically, if your score hits the entry. The Achievement xxx can only be reached, if the Online-Score is full, which means 100 entries, and your client is connected to the server. If your device (or the server) is offline, your score will be saved locally and uploaded on the next connection.
