I haven't tried the site I'm still reading a lot of reviews before trying so that each of my satoshi's will be worth to gamble because I'm not that person who keeps on gambling without asking other people's opinion on a certain site. And it seems I have a doubt for this site because I can't understand either on how it is going to be played. But still, kudos to the admin for he is very active here in forum and that is making me want to pursue my sight for his site.
