If you want to make it provably fair, I have an easy solution for you.

Make a server seed, and keep it private until after the flip, but provide a hash of it before the flip.
Let the client set a client seed.
Hash the two together, and if the first character of the hash is 0-7, the result is heads.
If the result is 8-f, the result is tails.
Set a new server seed after each flip, and remember to give the hash to the player before every flip and reveal the seed afterwards.

Alternatively, instead of setting a server seed after every flip, use a nonce, where it is incremented every flip and included in the hash that determines the roll so that you don't set a new server seed every flip. You would hash the client and server seed with the nonce and still follow the steps above.

This type of thing seemed to be required int he bitcoin community before any credibility is given to a new site. Plus people like to see a bunch of payouts to winners. GL going forward.

Not provably fair?

The result returned ( Head or Tail ) is generated randomly by the computer

http://www.random.org/coins/?num=1&cur=60-usd.0100c-washington

And we have only your word for that. It is trivial to, for example, make every 100th roll not take a number from that website and automatically lose, giving the house a higher edge than advertised.

Researched what provable fairness means and implement it. A Bitcoin-casino that doesn't even make an attempt of implementing provable fairness has no right to exist.

got it. Thanks for the comment, I will implement it asap Cool
