It seems to me like a large portion of the bitcoin economy is in gambling, and understandably so.
There's everything from Peerbet to SatoshiDice to Sealswithclubs. There are a lot of options, but not many of them have exceptional odds. (peerbet excluded of course because they apparently don't skim a little off the top)
I just set this site up where the odds are 97.5% 1.15x payout:
