Online Casino Games
The term ‘online casino games’ has now come to incorporate several casino game genres as software providers become more creative in the types of games they feature.
In this casino games online guide, we shall go through the most popular game genres and provide useful links to the best tips on how to play. We also feature trusted casinos where you can choose to play your preferred online casino game.
Popular US casino games by type
The best USA casinos offer a good range of casino game genres to ensure that different players can find a game that fits their specific preferences. Below you can find some of the most popular casino games you can find within the online gaming world:
The good news? The majority of US online casinos offer a free demo version of each casino game you decide to play. This means that you can play free slots and free live dealer games to test out the game and learn the tricks well before actually betting on real money games.
The most popular casino games to play
Slots, blackjack, online poker, and roulette are the most popular types of casino games, but there are lots of different variations to consider. We have highlighted the top games within each category below.
1. Divine Fortune – Most popular slot game
Divine Fortune is a progressive jackpot slot from NetEnt, which is available at most real money online casinos in the United States. The theme is Ancient Greek mythology, with symbols such as a Minotaur, Pegasus, and Medusa appearing on the reels.
This 5-reel, 20-payline slot has a return to player (RTP) rate of 96.59%. That equates to a 3.41% house edge, which is lower than the average slot. The progressive jackpot can exceed $1 million at some online casinos, so this game is popular with players hoping to earn a large reward from a single spin.
2. Zappit Blackjack – Most popular blackjack game
This is an entertaining blackjack variant, which allows you to “zap” your hand if you are dealt 15, 16, or 17. The round then ends, and you get your money back. That is a useful feature, as those hands are unappealing.
However, there is an extra rule when you play Zappit Blackjack: you will not win if the dealer goes bust on 22, as your bet will be graded as a push instead. That increases the house edge to 1.13%, so you will benefit from a lower house edge if you play classic blackjack instead.
3. French Roulette – Most popular roulette game
French roulette offers a house edge of just 1.35%, which is significantly lower than European roulette and American roulette. Whereas American roulette wheels feature a single zero and a double zero, there is only a single zero pocket on a French roulette wheel.
Some French roulette games have a rule called la partage, which earns you a 50% rebate if the ball lands on the single zero. Others have a rule called en prison, which gives you the chance to win your money back on the next spin if the ball lands on zero. Those rules are unavailable on European roulette games, so the French version is the best option.
4. Game King – Most popular video poker game
Bonus Poker, Bonus Poker Deluxe, Double Bonus Poker, Double Double Bonus Poker, Triple Double Bonus Poker, Deuces Wild, Deuces Wild Bonus Poker, and Joker Poker.
The basic idea is always to create the best five-card poker hand, but the payout rates and odds vary according to which variant you select. Deuces Wild is the game with the lowest house edge (0.28%), and Jacks or Better is the most popular video poker variant.
5. Ultimate Texas Hold ’Em – Most popular poker variant
Ultimate Texas Hold ’Em is the most popular table poker game at online casinos. This game is similar to video poker, as the goal is to create a strong five-card hand, but your hand is compared to a dealer’s hand at the end of each round. You will receive two cards, and there will also be five community cards, so this game appeals to Texas Hold’em fans.
This game is slightly more complex than video poker, Caribbean Stud, and 3 Card Poker, and it also gives you the chance to bet aggressively if you like. The house edge is just 0.73% if you make the right strategic decisions.
Live dealer casino games
These games allow you to connect with a real dealer, who will be located in a professional studio or a land-based casino. They are designed to replicate the experience of visiting a physical casino, but you can play on your phone or computer whenever you like, so they are more convenient.
You can make your plays and watch each round unfold in real time. The host will deal the cards or spin the wheel, and a chat box will allow you to communicate with the dealer and your fellow players. These are some of the most popular games to play at best live dealer casinos.

This table game is a variation of five-card stud, which is based on three player cards and two community cards.

However, it has a higher house edge than video poker and Ultimate Texas Hold’em.
Mississippi Stud
- House-banked poker game introduced by Shuffle Master CEO Mark Yoseloff
- Available at BetMGM, BetRivers, and other leading online casinos
Mississippi Stud is a table game that was created to capitalize upon the poker boom of the 2000s. This game is different to most other house-banked poker games, as your hand is not compared to a dealer’s hand. In this regard, Mississippi Stud is similar to video poker, and it has a low house edge too.
3 Card Poker
- Debuted at Mississippi’s Grand Casino Gulfport in the 1990s
- Available at casino apps such as BetMGM and Caesars Palace
This is a straightforward poker-style game in which you are dealt three cards. There are two popular side bets: Pair Plus and 6 Card Bonus, which offers payouts of up to 1,000x.

Ultimate Texas Hold’em
- Offers more betting options than most other table poker games
- Play it at BetMGM, BetRivers, Caesars Palace, or DraftKings
This popular house-banked poker game allows you to bet more aggressively than 3 Card Poker and Mississippi Stud. You can bet 3x or 4x the ante after receiving your two starting cards, which gives you the opportunity to capitalize upon strong hands. If you play correctly, Ultimate Texas Hold’em has a house edge of just 0.73%, which is competitive.
