What the hell. So I invited my friends on facebook for 2 coins, one of them said they actually installed it and playing it, he said he got the 2 tank coins but I didn't. This isn't what it says on the earn tab, don't lie to us kChamp.
I haven;t been able to get anyone to play ssl2 on fb from my invite since the reward was randomly changed from 3 to 2 I have convinced 14 people to play a random fb game,give me more credit kchamp... So yea i can;t confirm this but it worked when i got my 42 tank coins because 14x3 By the way have you refreshed?
