The zapper is random and so unfortunately you can get duplicates.

I haven't got too many new ones but I have gotten new ones. I just got the weird watery skin today so I know it is possible to get new ones. I know it is frustrating but it is the luck of the draw.

The Flameo skin is not a zapper skin. It is an achievement prize for being burned by the red rreign. So you have a chance to get that coming up :D

Guys, I am going to close this up. The zapper is random and if it were broken or skewed, no one would be getting new skins. You guys are welcome to make a feedback board if you wish but I am locking this one.
