UPS walked in with my Kickstarter copy of Caveman Curling this morning. (YAY!!)
As I went to sticker the game, I noticed that the tops of the Black "rocks", where you put the stickers, is white. A tiny tad annoying if, like me, you can't cover it fully with the sticker. I see from the picture that Eagle & Gryphon Games posted of this "clan" that this is a common issue. The red and yellow clan pieces don't have this problem as they are painted almost all the way around.
OK, I'm done complaining. I guess I'll be Sharpie-ing my rocks!
Mostly I'm very happy my game arrived safely! Thanks Eagle / Gryphon!
I believe that the 'White' that you are talking about is the spray that was put on the bottom of the rocks to make them slide easier. All the rocks (including the red, yellow, and white) have this spray. I took this as being the 'shiney' side.
