Realtime Gaming (RTG) is an American casino software provider founded in 1998 in Atlanta, later relocating its headquarters to Costa Rica. The company focuses on slots, table games, video poker, and progressive jackpots, offering a library of 300+ titles. Popular games include Aztec’s Millions, Caesar’s Empire, and the Bubble Bubble series, with many slots known for massive jackpot prizes and wide mobile compatibility.
RTG is particularly notable for serving the U.S. and other restricted markets where many European providers do not operate. Most RTG casinos hold licenses from jurisdictions like Curaçao or Panama, which are considered less strict compared to regulators such as the UKGC or MGA. While its reputation is less prestigious than brands like NetEnt or Microgaming, RTG remains one of the oldest and most recognizable names in the online casino industry.
