I did look at mbit but it seems it is linked to cloudbet. They have same dealers and everything . Even interface was almost same.
Yes, thats because the live room they host are the same . There are also many other sites which essentially has the same room, but the sites are different. They just rent the live feature from these companies.
EDIT: If you want another site with a different live table or room then check out Jetwin. They have a different live betting room .
