Hi guys,
I've recently launched
http://bitjack21.comIt's an online bitcoin blackjack game done entirely in HTML5. It's plays beautifully in all browsers including mobile. It uses standard casino rules:
* Dealer stands on all 17's
* Blackjack pays 3:2
* Double on any 2 cards
* Split to up to 3 hands
* Double after split (except aces)
* If aces are split, you get 1 card per hand.
* 1 "chip" is currently worth 0.01 BTC
* Minimum bet is 0.02 BTC (2 chips)
* Maximum bet will be increased later and is currently 0.75 BTC (75 chips).
* 8 decks are shuffled before every hand.
The "house edge" with this ruleset is razor thin, less than 0.5%, enjoy

I plan on adding roulette soon.
Thanks.
EDIT: As of 8/9/11 I have enabled the "crypto-proof" system on the website. This system is a mathematical PROOF that every hand you play at
http://bitjack21.com is 100% completely honest. (Technical details at
