We've had to increase the standard transaction fee to 0.1 LTC, which has also meant that the minimum bets for some addresses have had to increase as well (so that you would actually win something after fees!). When the upcoming Litecoin client based on 0.8.1 is released - which hopefully will have lower default transaction fees - we'll be able to reduce the necessary transaction fees as well.

So far we've had 225 bets win a total of 178.7 LTC.
