Here is the first PostCoin wheel. Try your luck. THe confirmation time is set to 15 minutes, so don't be afraid if the coins don't appear in your wallet instantly.
OP and Website updated with the link
http://altcoinix.com/games/postcoinJust checked the wheel its cool but do we have to deposit to play, because i am not seeing any free coins to play, If it is like deposit and play then i think it is like dice gambling.
