I think this is no different than the slots you find in casinos or those video poker machines in some bars.
Basically the house edge is clearly a rip-off but people are still playing their game.
All they need is a few gamblers a day and it's goodnprofot for them.
I dunno how house edge is calculated. I check winning % in bet history. Right now, there are 5 10x wins out of last 50 bets. Which means, winning ratio is 50:50. Is not it good?
Moreover, dice sites, that require user to sign up, may track betting pattern of a gambler and generate random numbers accordingly. This probability is absolutely non-existent in this game.
Most of the wins on the bet history are from the site administrator himself. Just look at the history of this site. The site operator tried to lure in some gamblers with his so called 0% house edge. After some people started to play and lost lots of money, he changed to 37% house edge and also reduced maximum betting amount. Chain-bet.com just scams you in a very clever way.. so be careful
