Linking The Royal and The Coral, this world-class casino spans a 7-acre lagoon and offers high-limit gaming, expanded electronic tables, and more slots than ever. As the sun sets over Paradise Island, guests step into a world of sophistication beneath soaring ceilings and striking Atlantean sculptures, where 80 expertly run table games, including Blackjack, Craps, Roulette, Baccarat, and Mini-Baccarat, are played with Las Vegas rules. Owned and operated by Brookfield Asset Management, the resort's casino floor spans 50,000 square feet, making it the second largest in the Caribbean, and includes Cleitos, an elevated table gaming experience just off the casino floor offering private or semi-private play, along with private gaming rooms, 700 slot machines, and a Sports Book. Guests can sign up for a player's card at Casino Guest Services to earn perks such as free play, comped stays, and VIP tournament invites.

Beyond the main gaming floor, Atlantis offers several distinct experiences: The Cove Pool, an adults-only retreat (18 and older) where guests can play Blackjack and Craps while taking in poolside and ocean views; Sea Glass at The Cove, offering an intimate mix of slot machines, electronic roulette, and Blackjack tables for a relaxed evening of play; and daily gaming lessons with a dealer at 3pm, covering the rules and strategies of major games such as Blackjack, Craps, and Roulette, with private group lessons available upon request. The casino employs approximately 815 personnel licensed by the Board, and its overall theme centers on a spectacular marine habitat and the underwater ruins of the legendary lost city of Atlantis.
