I'v been placing bets on there test net for about a week now, it runs ok, I ran into a few bugs but nothing critical. From the looks of it they have a pretty good dev team It's pretty fun, quite a few users online, lots of bets. Best part is that i have won all my NBA bets!
I agree, their bounty game/app runs pretty well. I ran into a few bugs a couple weeks back but it seems to be running smoothly since then. I have been able to get some friends from school and from the office to join up, it has become really fun with everyone involved; I now fully understand this whole "social gambling" concept haha. I've been successful on all my NBA bets except for 1!!
