I am developing this: coindice.com

Hi all,

I just signed up. Last week I’ve been developing a brand new dice game for Bitcoin.
The website is currently in private beta.

You can win Bitcoins in two ways:

1.   Collecting the Jar of BTC you build during a single game
2.   Throw the dice with the Jackpot

Here are some preview screenshots. I'm curious about your comments!

How do you plan to prove, that the rolls are truly random and the house edge is constant?

[Jack Lake]

Good question!

I was looking into https://bitcointalk.org/index.php?topic=77206.0 (Using SHA512 hash as random number generator for Gambling services) but I can’t seem to find a way to implement this solutions.
So I was thinking to create multiple (virtual) wallets:

•   The jackpot (50%)
•   The back-up jackpot (if someone wins the jackpot, the jackpot will be refilled with this back-up) (5%)
•   The jar wallet (this wallet will be used to payout the collected jars) (40%)
•   The house wallet (this wallet will not be touched by the game anymore) (5%)

Besides that I want to show the last played games to everyone, so you can see the throws, the win/lose status, the level and the jar.

If you have a better solution please let me know.

It is my goal to make the game as fair as possible!

But, what is the payout of the jar when winning?

Does that mean that the payout is proportional?  Or is it a static number whenever you win.

Describe the dice, how many winning numbers are there?

Hi chriswen,

Thanks for your reply. One game is not a single throws, the player can throw the dice until he hit the DEAD or the JACKPOT side.
Let me explain the sides of the dice:

Side 1:
Level up! There are five levels (represented by different colors). If you hit level 5 (the orange dice) this side turns into the JACKPOT side

Side 2:
Level down!

Side 3:
Win BTC in your Jar! In higher levels more BTC is added to your Jar. This number is also random

Side 4:
Lose BTC from your jar! In higher levels more BTC is removed from your Jar. Your jar cant go below 0 so you never have to pay extra for a game

Side 5:
Nothing happens really. Except your luck is growing, your “luck” can save you in some cases.

Side 6:
Your DEAD, game ends


To make the game more transparant I've added an overview of the last 100 played games.
