Which is exactly what they have said in the past when this issue has come up.  There is no such thing as "provably fair".  It's all just smoke and mirrors.  The only thing that is provably fair is a BTC transaction.  And unless you want to wait 10 mins or more between every roll,  you cant really use it for a dice game.  The only exception to that would be ethereum as the wait between rolls would be somewhat reasonable.  Its quite possible to create a dice game using ethereum hashes for dice rolls for a 100% provably fair game.  However that would put more strain on ETH's network than even the kitty crap.  Also,  wetsuit is not interested in a truly provably fair game since it would cut into his bottom line,  so obviously he'll never go that route even if it were possible.

However, until then,  all you have is my bot (http://dlive.tv/btctrading) to help you be successful and you just have to let wetsuit cheat with his stupid server seed changing tactics that we all know is happening.
