I found you had used many Adv. for player to get some event reward.This is a good strategy to get some revenue. I believe you can get the result in a short period.But, playing game is a time stick business.The Adv. will attract player to try other games. And those games will lead the player stick some time on the game you advertised.Which means you will see the play time accumulation dropped.My suggestion is to analysis not only the revenues you get from Adv. but also the accumulate playing time trend.So, to do Adv. or not to do is very important strategy change. You have to think more detail.Or, how to make players play bigger bet may be more suitable from my point of view!
