I got this off their website this afternoon. If it's correct, it looks like they may have changed things since the last time you looked.
In case my link didn't work, basically it says 1 crown for .25/.50, 2 crowns for .50/1.00, and 4 crowns for 1/2.
Either way, I'm gonna try it out in the next week or so, so I'll find out then for sure. If it's correct then does that make it a 12x bonus? That's only slightly worse than Empires monthly 10x which I never have any problem clearing. Hopefully it won't be the rock garden that Empire has become though. I sure wish PT and PA HUD supported it.
