SkyRama is annouced to be a "social game", the friends plays a important part in game. But unlike the games on Facebook, some people are confused by how to add buddies in SkyRama. So, the -creed-, the admin in the official forum made a guide of how to add buddies. Check below

1. How do I add buddies

Simply Click on the "Add Buddy" button on your toolbar


This will open the box below which will allow you to enter either the screenname or if you wish to invite new players the email address of those you wish to add.



If they accept your invite they will be added to your list 

First click on "Flights"  from the toolbar shown above

Then Click on "New Flights" and select the plane you wish to use.
Click on the country you wish to visit, then get your plane ready and sent it on it's way.

If the player is online at the time and services your airplane you will receive buddy points  for each plane you service. The number of points varies by plane type.

Likewise If you service a plane for another player you will earn buddy points as well as coins and experience.

For each aircraft from a friend that you can service and turn around within the allotted time, a certain number of hearts (Buddy Points). You can get this heart, even if you send a friend an airplane and he fails to do this. 
As the number of buddy points you share with each player increases your chances of getting a rare item from the flight increases.

You can visit your buddies by over their name in your toolbar as shown below 


If you visit you will be able to marvel at their airport watch your friend, if present, You can also pick up a few (up to 5) passengers for your own airport. 

Do not worry, as these are not taken from your buddies total, so it's worth every day dropping by your buddies airports.

When friends send planes and you can not land and service them, they return after the time expires back home again. Your friend then gets less and you gain no AirCoins Buddy Points or experience.

The plane disappears from your airport and return to Sender. In this case there are no points or other benefits for you for dispatching (same as if you were offline).

Remember, The more planes you send to online buddies, the more buddy points you will share and the higher your chance of getting rare items for your collections
