Alright, I've made some adjustments.  I've lowered the payouts, and raised the bet size to .1 BTC.  If this does begin to raise the prize pool over time, I will definitely bring back min/max bets, to encourage a little more action.  Thanks for your input!  All the changes are live, and considering no one has purchased any tickets for the current game, I don't feel like I'm changing the rug under anyones feet...

Thanks again
