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!
