maybe you need to try the game on the site games.bitcoin.com, I just answered your question is actually very difficult for me to answer
That's an odd looking site.. Better to use some trusted sites rather than this one.
If you're going for big then try directbet or nitrogensports. And don't panic if you won't get confirmations of the transfers in 24-48 hours..
I dont understand why you only can bet big amount on directbet and nitrogen? There is so many sites out there that offer huge amount of max win though. For me, I agree that directbet is a great site but it is only good for their sportbetting for their casino games I seldom play it
