Helicopter orders bonus coins.

[PspPopeye]

Some orders I fill give coins, experience and bonus coins. Why do some but not all give bonus coins? I want to get more bonus coins. Any advice?

Hi Popeye

We get bonus for the product done in a factory we upgraded for coins or XP. As you will upgrade your factories at the Academy, you will see more of these bonus.

Ah! Thank you for that answer. It was driving me crazy not knowing why I was getting bonus xp sometimes!
