We have a unique skin drop system: during the game, in a completely random way, any PREMIUM player can get a skin and have the opportunity to sell it, or withdraw it on Steam.

We strongly recommend that you forget about this feature, because it was introduced as a rare nice bonus and the chance of getting a skin is extremely small. It is better not to rely on the skin, but to forget about the drop, and perhaps someday you will be pleased with a nice bonus. Or maybe not.
