There are many great companies and casino software providers behind bringing popular games and fun online gambling experiences to players in the United States. One of the most notable names in the industry is Realtime Gaming, also known as RTG.
RTG has a long history in the online gambling industry. They were established in Atlanta in 1998, and for over 15 years, the company has been headquartered in Heredia, Costa Rica. Heredia is home to Herediano, one of the country’s most successful soccer clubs.
Many well-known online casinos work with RTG, including some of the best online casinos for U.S. players.
Best RTG Casinos
There are dozens upon dozens of online casinos with links to Realtime Gaming, but this quartet of casinos stands out from the crowd.
All of the casinos listed below offer generous bonuses for new and existing players and lots of great games to choose from, and players of all experience and interest levels can have fun playing their desired games at each of these sites.
1. OnlineCasinoGames
One of the main reasons why OCG is one of the best RTG casinos is the $20,000 welcome bonus package it offers, which is one of the most lucrative welcome packages in the industry, if not the most lucrative.
That bonus cash is spread out between two OnlineCasinoGames bonus codes—one for non-crypto deposits and one for crypto deposits, with both offers eligible for use provided your first overall deposit is not with a non-crypto method—and eight total deposits.
Making a deposit at OCG gives you access to RTG progressive jackpot slots such as Aztec’s Millions and Megasaur, as well as more than 200 other games.
It also grants you access to OCG’s loyalty program, which rewards players with higher withdrawal limits.
