I play the game on Facebook. When I try to earn Tank Coins, all it says is "Coming Soon." Does earning Tank Coins work on other sites? Why doesn't it work on Facebook?
While I don't understand the reason for it not working on Facebook, it probably has something to do with legality issues. I get on Kyle for a lot of things but some websites just won't allow it for various reasons. If you play from Kongregate, there's no options at all to earn Tank Coins. Not even so much as a referral system like on Facebook. I'm afraid you'll just have to work with what's available to you, like we do.
