solution, short answer: advertising!!

Long answer:

An advertising admin!

getting an admin just for advertising or an admin who has an extra job "advertising".
Let's make the perfect list of what an 'advertising admin' should be like and what he can do.

First of all, the juicy stuff, what should he be able to do?

*get new players
-advertise via facebook
-advertise at the other graal games
-update the app store and android store description
-ask the playerbase to advertise the game

*get existing players to play longer
-give free EC more frequently
-make new event-ideas
-brainstorm about new features that can improve the game
-get more daily things into the game (as example: happy hour: digging shells spawn twice as fast)
-get more admin-players interactions (we do have a meeting lounge, an opera hall??)
-adding more achievements

*get more payment going in the game:
-hosting rare auctions more often
-more exclusive stuff

Sounds juicy ay? as a normal player, your time online surely would get more fun. But who could become such an admin giving the players a joy of a time?
So secondly: who? We need an admin that understands the playerbase through and through. As a true advertiser, he or she knows his public in every vain. Surveys and questioning the playerbase are his tools to give the players and the new players a fresh new way of playing the game. a supersocial positive loyal and truthful person. He or she is the heart of the playerbase and knows everything the playerbase wants. He or she will do everything to get the people excited via advertisment out of the game and in the game.


I guess this is the way I would solve this problem
