I've built a delightfully simple bitcoin game called Kingcoin (at http://kingco.in) that I'd like to share with the community. Spin a multi-colored wheel and match various patterns (like, hitting the same color three times in a row) to win. You can try it out for free and play for real bitcoins when you're ready. Kingcoin uses a slight modification of Bitzino's technique to prove that it's fair.

I welcome any and all feedback! I plan to make the game even more fun by introducing a daily jackpot, so stay tuned.

Thanks,
Sanjay

Some game parameters have changed to benefit the player.

• The expected value of Kingcoin has increased to be competitive with other games. It is now approximately 0.984.
• Game parameters are as follows: Black slice is 16% of the wheel (used to be 15%), King slice is 1.3% of the wheel (used to not exist), and other slices are a minimum of 15% of the wheel (used to be 10%).
• The maximum number of spins per game is now 5.
• Each game is logged in the database with more details (in case I have to process refunds)
