Hence, the number of new US casino sites are expected to increase rapidly where we strive to cherry-pick and list reviews of the very best ones. Depending on what state you are in, we will define whether the casino is new or not depending on when the online casino became available in the state rather than the history of the company. They all have a long history of operating online but are to be considered as new casino sites in the US, since they recently were allowed to have a presence in the market. In many countries in Europe, online casinos have been legal for decades where you might recognize brands like Bet365, William Hill or Unibet. We believe that new foreign casinos are healthy competition for the well known brands we might be familiar with in the US. Online, these well renowned casino-behemoths might not be performing as well as other new online casinos that are coming from other well established online markets. Browsing around for new casinos you will recognize a lot of casino brands that are well known in the US and have been operating in Las Vegas for many centuries.
