Cool!

So not exactly double.. but 1.98%!

Well its kinda 100% luck, i dont think people like that. Or should i say people with low budget, those rich guys will come with tons of btc and risk it all xD

yep cool just launched it :) , why not  8)

I think lots of peoples like that, not any risk if  he has good money management.
lets see how its going.  8)

Not provably fair?

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

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  8)

I am new to bitcoins how did you implement bitcoins API

What an awesome casino game. So simple to play and quite enjoyable.

Great!! thanks :)

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.

tried to deposit nothing shows up.....
