Yes, there are casinos in Sihanoukville—three of them, in fact. There’s Holiday Palace on Victory Beach, Fortuna near Ocheteaul and Serendipity Beaches, and the local Kampongsom City Casino & Hotel, near the Golden Lions.
Each of these casinos offer their own accommodation, and offer gaming machines, video type games, slot machines, video poker, and a variety of table games like baccarat, roulette, blackjack, and poker.
No matter which nightspot one chooses to spend time in, it is almost a certainty that a fun time can be had in Sihanoukville.
