I think we need to separate both of Wincoin and Windice coin, so it will not misleading people.

Wincoin (with hexagonal style) is an altcoin and has been abandoned from the developer, it's worthless and can't be used for anything.



While this is Windice coin (some people call it Wincoin too) is a coin created/provided by Windice and it worthless too since can't be exchanges. But it can be used to test a game from windice and they has a contest of owning the highest windice coin (as stated above).
